Seismic performance of a new beam-to-column joint of anchored prestressing strands in precast concrete structures
摘要
Abstract
A new precast beam-to-column joint with anchored prestressing strands was developed to solve the problem that manufacture and installation of conventionally emulative precast beam-to-column connections required high carefulness. Three full-scale cruciform specimens were tested under reversal cyclic loading to study their seismic performance including a monolithic reference specimen. The experimental results show that the proposed precast specimen has similar seismic resistance to the monolithic specimen. The stiffness, dissipated energy and equivalent viscous ratio of precast specimens are lower in the early stage of loading than those of the monolithic specimen, but they achieve higher level at later stage. Deformability capacity of the proposed connection can satisfy the collapse prevention level. The detail of a certain debonded length of the two bottom deformed bars in a precast beam makes little difference.关键词
