Abstract

In recent years, a new interest has in fact arisen in the displacement based seismic design, especially in tall buildings. Several contributions have already been submitted for the development of different procedures based on displacements with the aim to simplify the evaluation of seismic demands of structures. In this paper, an improved procedure based on displacements applicable to the analysis and design of tall buildings is presented and illustrated by examples. It is considered as a new procedure for estimating the seismic deformation of Multi-Degree-of-Freedom systems. An example of a calculation that highlights the steps involved in applying this inelastic response evaluation approach is included to demonstrate the simplicity of the method. The accuracy of the proposed procedure is verified against the Nonlinear Time History Analysis (NL-THA) results and Uncoupled Modal Response History Analysis (UMRHA) of a 9-story steel building subjected to El-Centro 1940 (N/S) as a first application. In the second application the accuracy of the improved procedure is verified against the nonlinear time history analysis results of two tall buildings. The comparisons showed that the new method gives accurate deformations.
