SEISMIC ISOLATION

Ideas, engineering and manufacture

Seismic isolation strategy The usual anti seismic design is based on the structural ductility that is the ability to undertake extensive plastic deformations which dissipate energy by hysteresis. In this kind of design large structural damages are allowed. Consequently, even if the structure collapse is prevented, expensive repairs are necessary after major earthquakes. No protection is guaranteed to the goods inside the structures. However, for strategic structures, such as hospitals, power plants, control rooms, and primary bridges, the functionality after catastrophic events is a primary goal to be guaranteed in addition to the structural integrity. The operating requirements after an earthquake event can be a task even more severe than the structure collapse prevention: for example, in a hospital, the large acceleration occurring during an earthquake could damage the electronic instruments and the service networks (gas pipes, etc) even if the structure integrity is not largely affected.

The whole isolation of a structure is obtained by placing adequate elastic supports in suitable positions in order to disentangle the ground from the structure allowing relative displacements.

On the contrary, the seismic isolation design, based on the concept of reducing the seismic energy transferred to structures, has proved to be the most effective design technology for protection against earthquakes; indeed not only the structure’s integrity is guaranteed but also that of the goods inside.

Period (sec)

Additional acceleration reduction can be obtained by adding damping capacity to the isolators (energy dissipation). Since larger displacements are due to longer periods and acceleration reductions, the goals of seismic isolation system design are mainly two:

Acceleration design spectrum 0.6000

Acceleration

The isolation principle is very simple: the idea is to shift the structure vibration period from low values (typically ranging from 0.3 to 1 seconds for a fixed base structure) where the ground acceleration is pronounced to longer periods (2-2.5 seconds) where the acceleration is highly reduced as shown in the figure below, where the ground acceleration spectra are plotted versus the vibration period.

•

reducing acceleration to a target value so as to avoid structural damages and to ensure the functionality even under catastrophic earthquakes, using a simple and cheaper design of the structure

•

keeping the relative displacement between the ground and the structure to acceptable values so as to allow a cost-effective design of isolators, joints and flexible pipe connections.

With "seismic isolation design" it is possible to isolate not only new but also existing constructions through the insertion of special devices between the base of the structure and its foundations. This concept is the key-point of the base isolation systems designed and manufactured by AGOM, based on rubber bearings made of high damping compounds (E-safe HDRB) and/or with a damping lead core (E-safe LRB). All the movements and displacements due to the earthquake are concentrated at the base of the structure avoiding strengthening the whole structure itself with different type of device; in this way any widespread damages are prevented.

The isolators are usually installed at the base of each pier or, in general, under each vertical bearing element; in bridges and viaducts, they’re often used in substitution of traditional rubber bearings. Agom E-SAFE seismic isolators are generally characterised by high stiffness in case of small displacements, behaving like fixed points in order to prevent movements due to wind, etc., and by a low stiffness under large displacements in order to react and to and absorb wide oscillations.

Guidelines for isolation system design In this section a simple guideline for design base isolated structure is presented, the design procedure is summarized in the following steps:

1.

Selection of the design ground spectrum that depends on the seismic area, the soil type and the structure importance factor

2.

Selection of the target period of the isolated structure

3.

Calculation of the isolation system horizontal stiffness to reach the target isolation period

4.

Selection of the optimal location of the isolators in the structure support points in order to reach, as much as is possible, the coincidence between the center of mass and stiffness

5.

Calculation of the structure base acceleration at the target isolation period

6.

Reduction of the base acceleration by considering the damping capacity of the isolation system

7.

Calculation of the isolators horizontal displacement

8.

Design of the isolators according to the reference code

9.

Once the isolator design has been completed, detailed design of the support (isolators plinth and local reinforcement) must be completed. Note that all around the structure sufficient gap must be provided in order to allow the horizontal movement due to earthquake (normally the gap must be covered by joints that could be simple plates or more complex where required for example in area where there is car transit, etc..)

10.

For particular application when required a fire protection to the isolator can be provided

Lead core rubber bearings – E-safe LRB Lead core rubber bearings are so named due to the insertion of one or more lead cylinders into the rubber bearing. The lead cylinder provides very effective damping during extreme movements. The Agom E-SAFE lead core rubber bearings consist of multiple elastomer layers separated by reinforcing steel plates moulded to the rubber, and can be manufactured in a rectangular or circular shape according to customer requirements. The lead insert in the core of the bearing dissipates the energy of the earthquake while the rubber, reinforced with steel plates, provides stability, supports the structure and isolates vibrations. This type of seismic isolator is able to support live vertical loads and low displacement horizontal loads (e.g. wind effects), while protecting and isolating the structure by absorbing the impact of earthquake tremors and by reducing oscillations.

After an earthquake the restorative properties of the rubber layers return the building to its original position. During the design and engineering phase the type of rubber compound with the appropriate G modulus value is selected according to the installation’s technical requirements and project specifications. The damping factor of lead core rubber bearings can be higher then 30%.

High damping rubber bearings –E safe HDRB The Agom E-SAFE high damping rubber bearings HDRB consist of multiple elastomer layers made of special dissipative rubber compounds, separated by reinforcing steel plates moulded to the rubber layer, and can be manufactured in a rectangular or circular shape according to customer requirements. In the E-SAFE HDRB isolator, the energy is dissipated by hysteresis by the special rubber compound during the cycles of horizontal deformation of the insulator. After an earthquake the excellent restorative properties of the rubber layers return the building to its original position. The damping factor of HDRB can reach 10-16%.

In the following figures some examples of the isolators performances in term of vertical loads, horizontal stiffness, horizontal force and damping are plotted. The curves are only illustrative of the general range of application of the isolators but the detailed parameters have to be checked for the specific projects (for example the same isolator can carry an increased vertical load if the horizontal displacement is reduced). Furthermore different design rules and country codes allow obtaining different performances.

Installation

The installation procedure of isolators generally depends on the structure type. The main steps are:

1. Check before installation. In order to avoid placements mistakes of the bearings, all the technical and description data, printed on the label, shall be checked and compared with the ones showed in the shop drawings.

2. Casting of the substructures. Substructures shall reach a level about 30 mm lower then the final level. In order to install the isolators suitable voids spaces must be provided to insert the isolator lower anchor bars. An easy way to leave the voids is to use corrugated steel pipes grouted into the concrete with a diameter at least double compared with the diameter of the anchor bars.

3. Bearing positioning and substructure casting. The isolators are placed at the final exact level supporting it by temporary wedge spacers; the maximum deviation from the horizontal plan does not exceed 0.001 radians. In order to fix the isolators and anchor bars a formwork around the lower base plate must be provided (normally a wood or steel formwork is used). Wedge spacers

To grout the isolator a high strength non-shrink, quick setting cement mortar with compression strength > 45 Mpa has to be used; if the thickness of the mortar exceeds 40 mm a suitable reinforcement shall be provided.

Bearing positioning

The temporary wedges used to keep the isolator in right position shall be removed after mortar hardening and remaining voids shall be filled by the same mortar. The level of the cement mortar shall not exceed bottom level of the isolators steel lower plate to avoid bearings embedding compromising the eventual future isolator replacement.

Substructure casting

Pag

4. Casting of the superstructure – cast-in-situ superstructure

Superstructure formwork must be arranged around the isolator upper steel plate and sealed with adhesive tape or foam to avoid concrete leakage during casting.

The formwork must be arranged in a suitable way to avoid embedding of the isolator upper plate into concrete to avoid bearing embedding compromising the eventual future replacement. The formwork must be supported at the design level during concrete pouring.

Formwork placing and concrete pouring

When the concrete has reached adequate resistance the supports and formwork have to be removed. At the end of the construction the isolators must be cleaned and the painting of the steel plates repaired if some damages occurred during construction.

Formwork removal

5. Casting of the superstructure - prefabricated superstructure

Holes for mortar injection

The isolators normally have upper anchorages that must be inserted into the suitable voids of the prefabricated structure.

After the prefabricated beam has been placed in the final position (the beam must be supported on temporary supports), the isolator upper plate must be surrounded by a seal (normally rubber seal with suitable injection and leakage pipes).

Prefabricated beam positioning and isolator fixing

The gap and anchorages voids between plate and beam have to be filled by high strength mortar.

When the mortar has achieved sufficient strength to transmit the weight of the bearings; the temporary supports shall then be removed. At the end of the construction the isolators must be cleaned and the painting of the steel plates repaired if some damages occurred during construction. Temporarily support removal

Rubber compound properties

The nominal G values for the isolators design is: G =0.4 Mpa, damping 10% for soft compound G =0.8 Mpa, damping 10% for normal compound G =1.4 Mpa, damping 16% for hard compound

4.50 4.00 3.50 3.00 G ( γ ) / G(γ = 1)

The energy dissipation capacity depends on the high damping property of the elastomeric compound. Normally the special rubber compounds used for the production of the Agom E-SAFE HDRB isolators has an equivalent dynamic shear modulus G variable from 0.4 to 1.4 Mpa and a damping factor from 10 to 16%.

The special rubber compound used for the manufacturing of the Agom E-SAFE HDRB isolators have suitable additives to ensure the durability and the stability of the device performances in time, as experimentally tested in laboratory by accelerated artificial ageing tests according to common standards (European code prEN15129, Italian O.P.C.M. n. 3431).

1.25 1.20 1.15 1.10 ξ(γ) / ξ(γ=1)

The high damping rubber compounds shows an important variation of the dynamic shear modulus G as a function of the shear deformation (an example of the measured G modulus is shown in the fig. 1). The shear modulus G values becomes quite stable for shear deformation between 1 and 2 that is the normal range of functioning in case of earthquake in order to guarantee a stable horizontal stiffness to isolate the structure; for small shear deformation (typically smaller than 0.5) the increased value of G allows to limit the horizontal displacement due to service loads (wind, etc..).

E-SAFE HDRB standard range The Agom E-SAFE HDRB isolators are suitable for the seismic isolation of different structures (residential buildings, hospitals, power plant and bridges) and a very wide range of isolators can be manufactured to reach the target stiffness, displacement, damping according to the structural engineer requirements. In the following pages standard isolators classified at different displacement values are shown, in any case for the seismic isolation system design, Agom can adjust the isolators design parameters to satisfy the specific requirements and assist the structural designer in selection and optimization of the isolation system in order to verify the technical feasibility and the costs minimization. In the tables of next pages the general design of the E-SAFE HDRB isolators with rubber compounds with different G and damping values (from 10 to 16%) are shown. Adding the lead core, the E-SAFE LRB isolators can be designed in order to reach increased level of damping of to 30% with a large range of horizontal displacement and vertical load capacity. The isolators listed in the following tables have been designed according to European codes: -

prEN 15129 (for seismic load condition) EN 1337-3 (for non seismic load condition when the isolators act as normal rubber bearings)

and according to the following criteria: -

-

-

The horizontal seismic displacement range is from 100 to 400 mm. The reference displacement has to be considered as the maximum ULS (ultimate limit state) already increased by the safety factors required from the different codes (prNE15129, EN1998.1, EN1998.2) The horizontal non seismic displacement used for the static checks is taken as 0.5 times the total rubber thickness The stated vertical loads are the maximum that each isolator can support applying the horizontal displacement given by each load condition (seismic or static). The loads have to be considered as the maximum ULS already increased by the safety factors of the different codes (prNE15129, EN1998.1, EN1998.2) The considered rotation value is normally 0.005 rad

Since the isolators checks depends on the combination of multiple inputs (load, displacement and rotation) the Agom engineers can assist the structural designer for design optimisation.
