摘要
为研究PSRC梁预制部分的力学性能,以截面形式和剪跨比为参数,完成了9根PSRC梁预制部分的单调静力试验;试验结果表明,在剪跨比相同时,矩形截面试件承载力最大,V形其次,U形最小,三种截面试件都拥有良好的延性和变形能力;剪跨比为1.5的试件有的发生斜压破坏、有的为剪压破坏,剪跨比为3和4.5的试件发生受弯破坏;在此基础上,应用ABAQUS进行数值模拟,模拟结果与试验结果吻合良好,验证了模型的正确性。
In order to study the mechanical properties of the prefabricated PSRC beams, the monotonic static tests of the prefabricated PSRC beams were carried out with the section form and the shear span ratio as the parameters. The results show that bearing capacity of the rectangular cross-section specimens is the highest, the v-shaped specimens is the second, and the u-shaped specimens is the smallest with the same shear to span ratio. The specimens with a shear to span ratio of 1.5 have baroclinic failure, while those with a shear to span ratio of 3 and 4.5 have flexural failure. ABAQUS is used for numerical simulation, and the simulation results are in good agreement with the experimental results, which verified the correctness of the model.
