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。
Taking a single-story single-span concrete structure as a model, the ABAQUS analysis of the mechanical properties of the frame of reinforced concrete equipment after being reinforced by profiled steel is carried out to study the stress and strain characteristics of the concrete frame member. Theoretical analysis results show that steel reinforced concrete frame can greatly improve the bearing capacity of structural members. Finite element analysis shows that the strengthened steel works well with the original concrete frame structure, and the bearing capacity of the frame beam is increased by about 1.36 times, which shows that the reinforcement method is feasible.
