(l China Architecture Design and Research Group, Beijing 100044, China; 2 Beijing Fangdi Architecture & Engineering Design Consultants LTD., Beijing 100080, China)Abstract: The tall building that torsional period ratio exceeded limit value is analyzed by an example of engineering, find out weak part in the structure, the method accord with seismic concept design be used to increase capacity of anti-torsion for integral structure through reinforce partial structural member. According with the criterion of engineering construction to probe into the ways which simply. rationally and reliably to solve the common problem of tall buildings that torsional period ratio exceeded limit value. Lastly, put forward some proposal.
Keywords: seismic concept design of buildings; torsional period ratio, anti-torsion stiffness; seismic fortificationg measures.
