装配式干式连接剪力墙的设计方法研究

STUDY ON THE DESIGN APPROACH OF PRECAST SHEAR WALLS WITH DRY CONNECTION

  • 摘要: 近年来,装配式剪力墙在实际工程中得以广泛应用。在其施工过程中,水平向相邻的两块预制墙板通常通过预留的后浇带装配在一起。该方法仍然需要大量的现场浇筑作业。因此,干式连接成为了进一步提高装配式结构施工效率和抗震性能的优化方案之一。该文针对一种新型装配式干式连接剪力墙的数值模拟及其设计方法开展了研究。建立了单层装配式干式连接剪力墙的有限元模型,并对其模拟了与前序拟静力试验相同的加载方案。模拟结果与试验结果吻合较好,从而验证了模型的有效性。基于以上建模方法,建立了2个具有不同参数的10层干式连接剪力墙的有限元模型,开展了Pushover分析,优化了干式连接件在高层结构中的设计。根据数值分析结果,提出了装配式干式连接剪力墙在高层建筑结构中基于振型的设计公式。

     

    Abstract: In recent years, precast shear walls are widely used in practical engineering. Horizontally adjacent prefabricated wall panels are assembled together with the help of post-casted areas during construction. Considerable amounts of on-site casting work are still required. Accordingly, dry connection has become one of the appealing alternatives for further increasing the construction efficiency and seismic properties of precast structures. This research was carried out for both the finite element analysis and design approach of a new type of precast shear wall with dry connection. The finite element model of a one-storied precast shear wall with dry connection was established to exert the same loading protocol as that of the prior quasi-static test. The simulation results showed a good agreement with the test results, and the effectiveness of the model was validated. Based on the same modeling method, two 10-storey models of precast shear walls with different parameters was established, and pushover analysis was performed to optimize the design of connectors in high-rise building structures. According to the FEA results, a modal-based design approach of precast shear walls with dry connection in high-rise building structures was proposed.
