【摘要】：为研究不同连接形式PC挂板-剪力墙体系的抗震性能,进行了4个单层双肢剪力墙足尺试件的拟静力试验。通过对比试件的受力过程和破坏形态,研究PC挂板与剪力墙之间连接构造的受力机理和抗震性能,进而验证PC挂板与剪力墙之间连接构造的合理性。为进一步优化该体系的抗震性能,补充关于新型隔离材料的直剪试验,并采用ABAQUS对带有新型隔离材料的PC挂板-剪力墙进行了对比分析。研究结果表明:带有隔离材料且仅采用限位装置的PC挂板-剪力墙的抗震性能优于其他两种连接形式;新型隔离材料削弱了PC挂板对主体结构抗震性能的影响及减少了PC挂板外叶板裂缝的出现,其结果更为理想。
[Abstract]:In order to study the seismic behavior of PC slab-shear wall system with different connection forms, quasi static tests of four single-story two-leg shear wall full-scale specimens were carried out. By comparing the mechanical process and failure pattern of the specimens, the mechanical mechanism and seismic behavior of the connection structure between the PC hanging plate and the shear wall are studied, and the rationality of the connection structure between the PC hanging plate and the shear wall is verified. In order to further optimize the seismic performance of the system, the direct shear tests of new isolation materials are supplemented, and a comparative analysis of PC hanging-shear walls with new isolating materials is carried out by Abaqus. The results show that the seismic performance of PC hanging-shear wall with isolation material and only limit device is better than that of the other two types of connection. The new isolation material weakens the influence of PC hangers on the seismic performance of the main structure and reduces the appearance of cracks in the outer leaf plates of the PC hangers. The results are more satisfactory.
