摘要:

进行了13块集中荷载作用下四边简支叠合矩形板二次受力的试验,对其受力性能作了系统的分析,提出了叠合面等剪应力线模型.试验结果表明:叠合板的受冲切承载力不低于条件相同的整浇板;叠合板中的两期混凝土强度较低的一种混凝土强度对受冲切承载力具有控制性.建议叠合板的叠合面可采用自然粗糙面,且叠合板抗剪设计中,除满足受冲切承载力的计算外,还应按所给抗剪应力公式验算叠合面上的剪应力.

Abstract:

The secondary stress test of 13 four-sided simple support superimposed rectangular plates under concentrated load was carried out, and the force performance of the four sides was systematically analyzed, and the isoshear stress line model of the superimposed surface was proposed. The test results show that the bearing capacity of the laminated plate is not lower than that of the whole cast plate with the same conditions. The concrete strength of the two stages of concrete in the laminated plate is lower and has control over the bearing capacity of punching and cutting. It is suggested that the composite surface of the laminate plate can adopt a natural rough surface, and in the shear design of the laminate, in addition to meeting the calculation of the bearing capacity of the punching cut, the shear stress on the superimposed surface should also be verified according to the given shear stress formula.
