摘要:
连梁作为剪力墙结构和核心筒的重要耗能构件，在房屋抵抗地震中起到第一道防线的作用。由于模拟连梁真实的边界条件和受力状态较难实现，所以连梁低周反复加载试验成为最难的结构试验之一。针对实现试件平动以及对中加载等问题，各国学者也提出了不同的加载方案。本文首先对已有加载方案和试验装置进行综述，借此考察和分析现有试验条件的优缺点，并自行加工制作了一套可实现连梁边界条件和受力形式的加载装置。该加载装置在试件一侧布置两个竖向作动器从而能够保证连梁保持上下转角一致，并监控作动器受力情况，结果表明两个竖向加载器对试验的受力影响较小。通过对内嵌钢板混凝土组合连梁的低周反复荷载试验，验证了该加载装置的可行性和适用性，试验结果达到预期目标，数据可靠，该试验方案可供选择使用。
Abstract:
As an important energy dissipation component of coupling shear wall system and core tube, the coupling beam played the first seismic line function in the building. Simulating the real boundary condition and the stress state of the coupling beam is difficult to accomplish, so the reversed cyclic loads test of the coupling beam is to become the one of the most difficult structural tests. Scholars of different countries have put forward different loading method to the issues such as the specimen keeps horizontal, align to load and so on. This paper summarizes the previous loading method and test device, and takes the investigation and analysis of the advantages and disadvantages of previous tests , then designed and manufactured a suitable loading device to realize the boundary condition of the coupling beam. Loading device installed at both sides of the two vertical actuator to ensure the both side of the coupling beam to keep some angle. Load of the vertical actuator is recorded in the process, and analyze the change of loading. Two vertical actors have less influence on the force of test. The reversed cyclic loading test of embedded steel plate reinforced concrete coupling beams was conducted using this loading program. The feasibility and applicability of the loading device are proved . T he test results is shown that the loading device can achieve the expected goal and that the data are reliable. The new loading program is an alternative program
