The Advances in Earthquake Engineering series is intended primarily for the transformation of frontier technologies, research results, and state-of-the-art professional practices. This volume comprehensively explores seismic design aids and nonlinear properties of RC elements in a form that enables practicing engineers and researchers to readily use it without solving complex equations. With step-by-step numerical procedures and supplemental online material, the text clarifies the complexities involved in estimating basic input parameters required for nonlinear analysis of RC beam and frame structures under seismic loads until collapse. With several case examples of beam and frames, this superior reference is ideal for academicians and graduate engineering students.
