摘要
为研究PSRC梁的抗震性能,设计了6个PSRC梁试件进行试验研究,同时使用ABAQUS软件对这6个试件进行建模分析。模型分析表明,试件的滞回曲线和骨架曲线与实验值吻合较好。在此建模方法的基础上,分析了剪跨比、现浇部分混凝土强度、预制截面形式、纵筋配筋率和型钢腹板配钢率对梁抗震性能的影响,结果显示,现浇部分混凝土强度和预制截面形式对试件抗震性能影响很小,剪跨比大的试件承载力小,变形和耗能能力都较强,提高试件的纵筋配筋率和型钢腹板配钢率可以提高试件的承载力和耗能能力。
In order to study the seismic behavior of PSRC beams, six PSRC beam specimens are designed and tested. ABAQUS is used to analyze the six specimens, the results of model analysis show that the hysteresis curve and the skeleton curve fit well with the experimental values. Based on this modeling method, the influence of shear-span ratio, cast-in-situ concrete strength, prefabricated section form, longitudinal reinforcement ratio and steel section ratio on the seismic performance of the beam are analyzed, the results show that the cast- in -situ concrete strength and prefabricated section form have little effect on the seismic performance of the specimens, the bearing capacity of large shear-span ratio specimen is small, deformation and energy consumption are strong, increasing the longitudinal reinforcement ratio of the test piece and the steel ratio of the steel plate can improve the bearing capacity and energy dissipation capacity of the test piece.
