Effects of infill wall models on vibration period and seismic response of a building
Abstract:
This research aims to investigate the effects of infill wall
models on the seismic responses of buildings using nonlinear
response history analysis. Two building models are considered:
one with infill walls modeled using equivalent struts with
parameters based on recommended guidelines for nonlinear
models, and another model where the equivalent strut is
modified to have a higher modulus of elasticity to match the
natural frequency measured from the actual building. These
models employ lumped mass models with linear frame
members and nonlinear strut models. Ground motions in the
analysis closely match the fundamental periods of each model.
Various responses of the building models, including shear forces,
column moments, and equivalent strut forces, are thoroughly
examined. The results reveal that the model with modified strut
stiffness imposes greater seismic demands compared to the
original model. The observations indicate unsafe scenario if the
building model does not account for the appropriate strut model
and accurate natural frequencies
