型钢混凝土梁-角钢混凝土柱框架抗震性能试验研究
|
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。
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 employed to calculate the hysteretic curves.The influences of slenderness ratio,axial compression ratio,steel ratio of column,cross-section moment resistance of the beam,ratio of steel bars and prestressing level on the skeleton curves are studied.The results indicate that this type of frame performs well if under earthquake.
