基于ANSYS钢筋混凝土简支梁极限荷载研究

Research on Limit Load of Reinforced Concrete Supported Beam Based on ANSYS

基于ANSYS建立钢筋混凝土简支梁有限元模型,对其进行了在集中荷载下,不同配筋方案对混凝土极限荷载的影响的研究。首先利用试验资料对有限元模型进行了验证分析。结果表明,对于混凝土简支梁极限荷载,有限元结果与试验结果吻合较好。然后对钢筋横截面分布、箍筋配筋率两个方面进行参数化研究,揭示了每种参数对极限荷载的影响规律,并根据计算分析结果,提出了几点配筋方案的建议。

Based on ANSYS,the finite element model of reinforced concrete simply-supported beam was established.The influence of different reinforcement schemes on the ultimate load of concrete under concentrated load was studied.Firstly,the finite element model was validated and analyzed using test data.The results show that the finite element results agree well with the experimental results for the ultimate load of concrete simply supported beams.Then the parametric study on the cross-sectional distribution of reinforcement and the ratio of stirrup reinforcement was carried out,and the effect of each parameter on the ultimate load was revealed. Based on the calculation and analysis results,several suggestions for reinforcement schemes were given.
