装配式钢框架-内嵌墙体新型连接件平面内承载性能试验研究
Experimental Study on In-Plane Bearing Performance of a New Connector for Prefabricated Steel Frame-Embedded Wall
针对传统外挂式墙体存在露梁露柱、内嵌式墙体在水平荷载下易损等问题,提出一种适用于装配式钢框架-内嵌墙体系统的S形钢板连接件,以释放墙体与框架间的约束,实现二者在侧向荷载下的变形协调。通过对4种规格的连接件进行墙体平面内的承载性能试验,得到了连接件在墙体平面内的拉压变形、刚度演化、承载力以及破坏模式。在此基础上,开展使用S形连接件的钢框架-内嵌墙体及空框架的柱顶水平往复荷载加载试验,对不同规格连接件的滞回性能进行了详细对比分析。研究结果表明,S形连接件可有效降低内嵌墙体在侧向荷载下的受力水平,使其基本不参与抗侧,实现框架和内嵌墙体之间的变形协调,从而避免水平荷载作用下墙体发生破坏,保障建筑的使用功能。该研究为装配式钢结构建筑中内嵌墙体的可靠连接提供了新思路。
To solve the problems of exposed beams and columns in external walls and the vulnerability of embedded walls under lateral loads, this study proposes an S-shaped steel connector for prefabricated steel frame-embedded wall systems. The connector relieves the constraint between wall and frame, enabling coordinated deformation under lateral loading. Four types of connectors were tested to evaluate their in-plane mechanical performance, including tensile and compressive deformation, stiffness evolution, bearing capacity, and failure modes. Based on these tests, cyclic loading experiments were conducted on steel frames with embedded walls using S-shaped connectors, as well as on bare frames, to compare the hysteretic behavior of different connector specifications. Results show that the S-shaped connector effectively reduces the lateral load transferred to the embedded wall, allowing it to remain largely uninvolved in lateral resistance. This ensures deformation compatibility between the wall and frame, prevents wall damage under horizontal loading, and maintains the building’s functional integrity. The proposed connection provides a novel solution for the reliable integration of embedded walls in prefabricated steel structures.
