The Design Spectrum Curve Of Seismic Performance For Reinforced Concrete Structure

摘要

The performance-based seismic design of structure is in a research and development situation. A method is proposed in this paper to adapt the present demand. This method is based on the current Chinese code for seismic design of buildings. In design process, the earthquake action and lateral displacement are considered, and thus the design spectrum curve for equivalent single degree of freedom system is established. Thus the performances of structure at different earthquake levels are obtained and checked to satisfy the design requirements. After accomplishment of design, an elasto-plastic static analysis of structure may be conducted to fully examine its performance.
