Derivation of Empirical Formula of Natural Period for Irregular Building with Shear Wall

Overall structural seismic damage rapid assessment method based on period and displacement response characteristics

“…In response to the shortcomings of the fundamental period of shear wall structures in the Indian seismic code, Mandanka et al 7 selected 23 irregular shear walls considering the stiffness regular with different planar dimension, structural height, shear wall size, etc., and analyzed the fundamental period of these buildings by using ETABS software. Based on the numerical simulation analysis data, a new fundamental period estimation formula for the stiffness irregular reinforced concrete shear wall structure is fitted considering influencing factors such as total structural height, structural width, and inertial moments.…”
