A accurate means to assess coupled lateral torsional motion of single story structures in the Central and Eastern U.S

ABSTRACT

An analytical procedure is developed that in part enables design engineers utilizing code planar force methods to acuurately acount for the additional lateral response for torsion in irregular structures subjected to seismic motion. Furthermore, a dynamic factor is devepoled which modifies the lateral displacements obtained from the code planar force methods to predict the earthquake demands for any seismic zone without requiring a 3 - dimensional dynamic analysis. Hence, the design seismic displacements above. The accuracy of the procedure is verified through example problems (AU)
