Experimental investigation and database construction of seismic performance of beam-column connections

Using high-strength reinforcement and concrete have many advantages, including smaller member sizes, lighter structure elements, lesser reinforcement, longer span capability, and more space available for end users. Also, high-strength concrete structures are usually sustainable. This project investigate how to extending current design methods for frame joints with high-strength reinforced concrete. We constructed an unified database made with over 350 reinforced concrete beam-column connections through extensive investigations. Based on database investigation, we design four interior joint specimens to evaluate the design provisions for frame joints. ©, 2014, Chinese Institute of Civil and Hydraulic Engineering.
