Displacement-based Design of Frames Consisting of Composite Beams and RC Columns

Performance-based seismic design (PBSD) method has been widely recognized in recent years, it can be used for the future structural design. And the direct displacement-based design method (DDBD) is one of the most effective ways to implement the performance-based seismic design (PBSD) theory in current. In this paper, aiming to the composite frame consisting of composite beams and continuous compound spiral hoop reinforced concrete columns (CCSHRCS), its DDBD flowchart is presented, and the structure identified performance objectives in the preliminary design process and specific seismic performance assessment methods are given. Finally, through the calculation results of CCSHRCS frame case that demonstrated the reasonableness of the method. It provides an effective tool for the seismic design of CCSHRCS frame structures
