Developments and Case Studies of the Draft Code for Performance-Based Seismic Design of Buildings in Taiwan

Abstract eng:
This paper summarizes the development of the performance-based seismic design draft code for buildings in Taiwan and presents results of case studies following the guideline in this paper. Based on the examination of the existing seismic design code provisions, several key issues are identified to determine the scope of performance-based seismic design methodologies to be incorporated into. The proposed seismic design objectives and criteria including drift limits, site feasibility requirements, conceptual design scopes and basic rules have been explained. Procedures for preliminary design and seismic performance evaluation have been presented. Suggestions on seismic performance criteria and performance evaluation of existing buildings have been made. According to the case studies, it is believed that seismic performance will be ensured with enhanced confidence through implementation of performance-based seismic design methodology into the current code of practice.
