Improved Procedure for Design and Evaluation of Structures: Single-Degree-of-Freedom Bilinear Systems

Abstract eng:
Current seismic codes require from the seismically designed structures to be capable to withstand inelastic deformations. Many studies dealt with the development of different inelastic spectra with the aim to simplify the evaluation of inelastic deformations and performance of structures. Recently, the concept of inelastic spectra has been adopted in the global scheme of the performance-based seismic design through capacity-spectrum methods. In this paper an improved procedure, applicable to evaluation and design of structures has been developed and illustrated by examples. This procedure uses inelastic spectra and gives peak responses consistent with those obtained when using the nonlinear time history analysis. The idea consists of solving the differential equation of motion for an increased horizontal displacement of the system. Also, is developed the modified Procedure A of ATC 40 for estimating the seismic deformation of SDOF systems.
