[摘要] 通過(guò)2個(gè)不同剪拉比下的預(yù)應(yīng)力混凝土扁梁框架內(nèi)節(jié)點(diǎn)試件的低周反復(fù)荷載試驗(yàn)，對(duì)節(jié)點(diǎn)的破壞形態(tài)、滯回曲線、延性、耗能能力等抗震性能進(jìn)行分析研究，并探討剪拉比對(duì)預(yù)應(yīng)力混凝土扁梁框架內(nèi)節(jié)點(diǎn)抗震性能的影響。

[關(guān)鍵詞] 預(yù)應(yīng)力混凝土；扁梁框架內(nèi)節(jié)點(diǎn)；抗震性能；剪拉比

Abstract: The pseudo-static test on two inner joints of pretressed concrete flat-beam frame have been camed out to research the seismic behavior, such as failure pattem, hysteresis curves, ductility and energy dissipation. And the effect of shear tension ratio on the seismic of inner joints of pretressed concrete flat-beam frame has been determined.

Keywords: prestressed concrete; inner joint of flat-beam frame; seismic behavior; shear tension ratio
