【摘要】：设计制作了15个部分预制装配型钢混凝土梁试件及2个全现浇型钢混凝土梁试件,并对其进行了静力试验,对处于正、负弯矩区段的部分预制装配型钢混凝土梁和采用蜂窝型钢的部分预制装配型钢混凝土梁的受剪性能进行了研究。通过分析试件的破坏过程、箍筋应变、荷载-转角曲线,对不同参数下试件的破坏形态、破坏机理和承载能力进行研究。结合试验研究结果,对影响预制装配型钢混凝土梁受剪性能的主要因素进行了分析。结果表明:部分预制型钢混凝土梁中预制部分与现浇混凝土能够很好地共同工作,部分预制梁受剪性能与现浇型钢混凝土梁无明显差别。
[Abstract]:Fifteen prefabricated steel reinforced concrete beam specimens and two fully cast-in-situ steel reinforced concrete beam specimens were designed and manufactured. The shear behavior of partially prefabricated SRC beams with negative bending moment and partially prefabricated SRC beams with honeycomb steel is studied. By analyzing the failure process of specimen, stirrups strain, load-rotation curve, the failure mode, failure mechanism and load-bearing capacity of specimens under different parameters are studied. Based on the experimental results, the main factors affecting the shear behavior of precast SRC beams are analyzed. The results show that the prefabricated part and the cast-in-place concrete can work together well, and the shear behavior of some prefabricated beams is not different from that of the cast-in-place steel concrete beams.
