RESEARCH ON SEISMIC PERFORMANCE OF PRECAST PRESTRESSED CONCRETE FRAME

摘要

Research on seismic behavior of precast concrete frame systems is important to extend their applying, and thus improve the industrialization of construction of China. Precast prestressed concrete frame systems, in which precast beams and columns are connected by bonded post-tensioned tendons, have many evident advantages. Seismic performance Of this type of structural system was investigated in this paper. Two precast ptestressed beam-to-column joints were tested under cyclic reversal loads first, and then a three-story, two-bay precast prestressed frame was designed, and its seismic behavior was evaluated using inelastic static analysis (Pushover Analysis) procedure, by the help of SAP2000.
