基于ANSYS的再生砖粗骨料混凝土梁受弯性能有限元分析

为深入了解再生砖粗骨料混凝土梁的受弯性能,通过ANSYS有限元分析软件,对不同再生砖粗骨料替代率和不同纵向受拉钢筋配筋率的混凝土梁受弯性能进行了模拟分析。结果表明:混凝土梁的有限元计算结果与试验结果吻合较好,有限元数值分析可以有效的模拟再生砖粗骨料混凝土梁的受弯性能;再生砖粗骨料替代率和纵向受拉钢筋配筋率对混凝土梁的极限弯矩与跨中极限挠度影响显著,再生砖粗骨料影响系数k在配筋率为1.01¹.48%范围内时稳定较好。

Finite element analysis of concrete beam's flexural property of recycled brick coarse aggregate based on ANSYS

In order to understand the flexural properties of recycled brick coarse aggregate concrete beams deeply, based on ANSYS finite element analysis software,the paper simulated and analyzed the flexural property of recycled brick coarse aggregate concrete beams with different replacement ratios of recycled brick aggregate and different longitudinal tensile reinforcement ratio. The results show that the calculation results of finite element fit perfectly with that of test.The numerical analysis of finite element can simulate the flexural property of recycled brick coarse aggregate concrete beams effectively; the replacement ratio of recycled brick coarse aggregate and longitudinal tensile reinforcement ratio have a great influence on ultimate bending moment and ultimate deflection of mid-span; the recycled brick aggregate influence coefficient k is stable when the reinforcement ratio is in the range of 1.01% to 1.48%.
