RC梁与柱在不同地震作用下的变形限值分析

分析钢筋混凝土(RC)梁与柱基于不同地震作用下的变形限值,对钢筋混凝土梁与柱进行低周往复循环加载拟静力试验.然后对试验进行仿真模拟,将试验结果与仿真模拟结果进行对比分析,发现二者结果相近,从而验证仿真模拟的可行性.在构件的荷载-位移曲线上获取屈服点、峰值点和极限点,分别计算这3个状态点对应的侧向位移值与构件计算长度的比...

Analysis of deformation limits of RC beams and columns under different earthquakes

To analyze the deformation limits of reinforced concrete(RC)beams and columns under different earthquakes,quasi-static tests were conducted on the reinforced concrete beams and columns under low repeated and reciprocal loading.Simulate the test,and compare the simulation results with the test results,and find that the two results are similar,verify the feasibility of the simulation.By obtaining the yield point,peak point and ultimate point of the load-displacement curve of the component,and the drift ratio is the ratio of the lateral displacement corresponding to the three status points to the calculated length of component under small earthquake,medium earthquake and severe earthquake,respectively.By adjusting the shear-span ratio of the beam and the column,the reinforcement form of the beam and the column,the axial compression ratio of the column,more load-displacement curves of components are obtained,and the test results and the simulation results are statistically analyzed to get drift ratio limit under different earthquake.
