Recent studies have shown that the configuration of centers of mass,
strength and stiffness can affect behavior of an asymmetric building. With change in
configuration of centers, damage parameters such as interstory drift and ductility
demand parameters may decrease. These parameters are good indicators of
structural and non structural damages during earthquake excitations. But decrease
of one damage parameter in specific centers configuration necessarily will not cause
decrease of another parameter. The importance of damage parameters relative to
each other in a building can be function of earthquake intensity, strength and
deformation capacity of building. In this paper behavior of asymmetric buildings
with different configuration of centers in different excitation levels are studied. For
this purpose 3D building models are subjected to both one directional and two
directional earthquake excitations and the ductility and interstory drift responses of
models are compared. The results have shown that for different damage parameters,
the proper configuration of centers is different, so to improve performance of a
building, proper configuration of centers corresponding to the critical damage
parameter must be used.
