| 摘 要： | 完成两榀型钢混凝土梁-角钢混凝土柱框架水平低周反复荷载试验,考察这类框架的滞回特性、骨架曲线、刚度退化、耗能能力、残余变形、破坏形态等抗震性能,并采用OpenSees软件对两榀框架进行滞回模拟分析。考察柱长细比、轴压比、柱含钢率、梁内型钢截面抵抗矩、梁配筋率及预应力度等参数对框架骨架曲线的影响。研究结果表明,此类框架具有优良的抗震性能,为其在抗震区的推广使用提供了参考依据。

| Abstract: | This paper presents an experimental and theoretical study of two frame structures of steel reinforced concrete beams and angle-steel concrete columns under horizontal low cyclic loading,respectively.Based on the test results,the hysteretic curves for the horizontal load-displacement and the failure modes are obtained.The hysteretic behavior,skeleton curve,stiffness degradation,energy dissipation,and residual deformation of the two frames are studied.The nonlinear structural analysis program OpenSees is empl... |
