SEISMIC RESPONSE OF BUILDING BASE ISOLATED WITH
FILLED RUBBER BEARINGS UNDER EARTHQUAKES OF DIFFERENT CHARACTERISTICS
natural rubber bearing has often been considered suitable because of its durability and easier fabrication
The base
isolation system consists in introducing low stiffness bearings and damper
between foundation and structure
METHOD OF ANALYSIS OF BASE ISOLATED BUILDING
The time
history analysis of the base isolated building is carried out using the
computer program 3D-BASISTABS. A full three-dimensional representation of the
structure is used in time history analysis of the base isolated buildings. The
isolation system is modelled as a bilinear hysteretic element. The details of
method of analysis are described by Reinhorn et al. (1994). Following
assumptions are made for the analysis of base isolated building:
- The superstructure is elastic at all time and the non-linear behaviour is restricted in isolators only.
- All frame substructures are connected at each floor level by a diaphragm, which is infinitely rigid in its own plane.
- Each floor has three degrees of freedom (two translations and one rotation) attached to the centre of mass of each floor. The isolation devices are rigid in the vertical direction and each has negligible torsion resistance.
- Effect of infilled walls on stiffness of the structure is negligible. These are considered in computation of mass only
CONCLUSIONS
Filled
rubber bearings are suitable for ground motions having high dominating
frequencies but is not effective for ground motions whose dominant frequencies
are close to natural frequency of base isolated structure. The fundamental
period for a bearing is unique for given bearing parameters but the damping is
found to be dependent upon the characteristics of input ground motion also.
Yield displacement can be used as an important parameter for controlling
damping in order to achieve desired base displacement.
