摘要
以一榀单层单跨混凝土结构为模型,对承载状态下的混凝土设备框架经型钢加固后的受力性能采用ABAQUS进行分析,研究混凝土框架构件的应力、应变特点。理论分析结果表明:型钢加固混凝土框架可以大幅提高结构构件的承载力。通过有限元数值分析可知加固型钢等与原混凝土框架结构协同工作良好,框架梁承载力提高了约1.36倍,说明该加固方法可行。
Mechanical Analysis for RC Device Framework strengthened by profile steel under load condition taking as a model of a single span and one story RC device framework,the mechanical perfromance of the frame strengthened by profile steel under load condition was analyzed by ABAQUS. The characteristics of stress and strain for the frame were also studied. The theoretical analysis results showed that steel reinforced concrete frame could greatly improve the bearing capacity of structure. Good cooperative relationship between the steel and original concrete frame was exhibited in FEM results. The bearing capacity of frame beams could improve 1. 36 times,which proved that the reinforcement method was feasible.
