Comparative Analysis of Seismic Performance-Based Design Provisions in Code for Seismic Design of Buildings and Technical Specification for Concrete Structures of Tall Building
The code for Seismic Design of Buildings(GB 50011-2010,2016 edition)and the Technical Specification for Concrete Structures of Tall Buildings(JGJ 3-2010)both have provisions for performance-based seismic design,albeit with slight differences.Engineers,in their execution,may inevitably encounter confusion due to these variations.This paper analyzes the provisions of both codes regarding seismic performance design,and explains the meanings of seismic performance objectives and seismic performance levels from the perspective of load-displacement curves.It also compares the design parameters of the two codes.By listing 29 engineering cases adopting performance-based design methods,this study analyzed the basis for determining displacement indicators.Based on the analyses of these two aspects,the differences in the specifications regarding performance-based design are summarized,and design recommendations are provided.
