摘要
通过对3根在梁的弯剪区段开定位矩形孔的开孔梁的有限元非线性分析,计算配置不同直径补强箍筋的开孔梁试件在不同荷载下的应力、应变、挠度、裂缝以及试件的极限承载能力,并与试验数据进行比较。将ANSYS在开孔梁的有限元分析中的有关参数的选择对计算结果的影响进行了对比。
By means of doing nonlinear finite element analysis on three concrete beams with large rectangular openings in fixed place inside the flexuralshear section,it was computed that the beam′s stress,strain,deflection,crack and the ultimate carrying capacity with different diameter reinforced bars under alterable loads.Which were compared with the test results.The effect on the result by selecting different parameters was also compared
