| 摘 要： | 为探究部分预制型钢混凝土梁的抗震性能，进行了7个部分预制型钢混凝土梁试件的拟静力试验，研究了试件的裂缝开展过程、破坏形态、承载能力、延性、耗能能力和刚度退化情况，探究预制截面模式、剪跨比和后浇混凝土强度等对其抗震能力的影响。结果表明:地震作用下，该7个试件力学性能较好，剪跨比是影响试件抗震性能的首要要素，剪跨比大的试件耗能能力强，型钢约束部分混凝土可以提高试件的耗能能力，截面模式和后浇混凝土强度对抗震性能影响不大。

| Abstract: | To study the seismic performance of partially prefabricated steel reinforced concrete beams (PPSRCB), the quasi-static tests of 7 PPSRCB specimens were carried out, the crack initiation process, failure form, bearing capacity, ductility, energy dissipation capability and stiffness degradation of the specimens were studied respectively, the effects of prefabricated section mode, shear span ratio and post-cast concrete strength on their seismic capacity were investigated. The results show that the mechanical properties of these 7 specimens are good under seismic load, and the shear span ratio is the primary factor that affects the seismic performance of specimens, the specimens with large shear-span ratio have strong energy dissipation capacity, the part-confined concrete can improve the energy dissipation capacity of the specimens, the effect of the section mode and post-cast concrete strength on the seismic performance is insignificant. |
