英文摘要: Abstract(#br)This paper utilizes experimental and numerical studies to investigate the seismic behavior of precast concrete frames. The system is composed of monolithic columns and composite precast concrete beams with debonded reinforcement at the beam end, with the purpose of distributing plasticity over a larger rebar length to improve the seismic performance of traditional precast concrete frames. Two half scale precast concrete frames, with and without debonded rebar, were tested under quasi-static cyclic lateral load. The observations during the test, load–displacement curves, stiffness, energy dissipating capacity and rebar strain are discussed. The experimental findings demonstrate that rebar debonding lead to reduced strain in tensile reinforcement. The decrease in strain due to...
