钢筋混凝土开孔梁受弯承载力有限元分析探究

Finite Element Analysis of Flexural Bearing Capacity of Reinforced Concrete Beams

随着城市人口的不断增长,城市高层建筑愈来愈多,人们对建筑物的功能需求也不断提高。为避免对建筑物梁下空间的挤占,通常采用腹梁方法。但由于孔洞的存在,会对梁截面的整体性及安全性产生影响,且目前尚无混凝土开孔梁的设计方案。此次研究以非线性模拟实验为基础,探讨钢筋混凝土开孔梁各项参数对其受弯承载力的影响,以促进开孔梁的实际应用。

With the increasing urban population, urban high-rise buildings are increasing, people＇s demand for the function of the building is also increasing. In order to avoid the misuse of buildings under beam, beams commonly used method. However, due to the existence of holes, it will affect the integrity and safety of the beam cross section. Based on the nonlinear simulation experiment, the influence of various parameters on the flexural bearing capacity of reinforced concrete beams is discussed.
