ABSTRACT
This chapter provides a detailed investigation on the global behavior of asymmetric structures. Presented is the peak angular drift response at the top of the buildings during bi-directional seismic excitation of the torsionally unbalanced structures. The structural internal cracking was first analyzed using the dynamic properties of the structure. In order to identify the ultimate state of collapse of a structure and structural performance, the horizontal displacement is primarily used as a threshold. The proposed drift limits are limited to the structure which falls under the scope of similar asymmetric structures. The three-story asymmetric shear wall structure was exposed to progressively increasing ground motions. For S-1 structures, it can be said that regardless of the direction of eccentricity and primary component of seismic excitation, translational motion prevails. The response of S-4 structures is predominantly torsional in the orthogonal directions. Moreover, the direction of the larger accelerations clearly corresponds to the direction of the stronger component of the ground motion.
