ABSTRACT

In this study, experiments are conducted to investigate the effect of wall-to-frame connectors on in-plane/out-of-plane (IP/OOP) behavior of the steel frames infilled with autoclave-cured aerated concrete (AAC) wall to find a reasonable connection type. Six infilled frames with different connection designs were tested. In specimens with V-shaped and T-shaped connectors, the OOP stability of the wall was maintained, the frame–wall interaction was ignored, and the wall remained intact up to 2.5% IP drift. They compensated the stiffness degradation and strength reduction of the frame after 2.5% drift. These two connectors can be used as prequalified connectors in the steel structures.

摘要

在这项研究中，进行了实验以研究墙到框架连接器对填充有高压釜固化加气混凝土 (AAC) 墙的钢框架的平面内/平面外 (IP/OOP) 行为的影响。找到合理的连接类型。测试了六个具有不同连接设计的填充框架。在具有 V 形和 T 形连接件的试件中，墙体的 OOP 稳定性得以保持，框架与墙体的相互作用被忽略，墙体保持完整，IP 漂移高达 2.5%。他们补偿了 2.5% 漂移后车架的刚度下降和强度降低。这两种连接器可用作钢结构中的预认证连接器。
