The "Advances in Earthquake Engineering" series is intended primarily for the transformation of frontier technologies and research results and state-of-the-art professional practices. This volume comprehensively explores seismic design aids andnonlinear properties of RC elements in a form that is useful for practicing engineers and researchers to readily use without solving complex equations. With step-by-step numerical procedures, in addition to supplemental online material, the text helps to clarify and simplify the complexities involved in estimating basic input parameters required for nonlinear analysis. A solid research directory for academicians, this volume is also a superior reference for graduate students in civil, structural, and construction engineering.
