【摘要】 为研究水平荷载作用下钢框架中不同连接方式的蒸压加气混凝土(ALC)板的抗裂性能,以及不同饰面做法抗裂性能,设计并进行了三榀足尺两层单跨钢框架-内嵌ALC墙板的低周往复荷载试验。通过对比不同连接方式墙板破坏演化过程,得到了内嵌蒸压加气混凝土墙板的破坏模式,分析了连接方式对蒸压加气混凝土墙板抗裂性能的影响,以及不同饰面做法的抗裂性能。结果表明:内嵌ALC板以墙板连接件处开裂为主要破坏方式;内置锚连接方式墙板抗裂性能优于钩头螺栓连接方式和滑动螺栓方式;墙板与钢框架接缝位置饰面为抗裂薄弱位置,墙板拼缝位置饰面抗裂性能良好,双组份密封胶填缝抗裂性能好于单组份密封胶。更多还原

【Abstract】 In order to study the crack resistance of autoclaved lightweight concrete(ALC) plate with different connection modes in steel frame under horizontal load and the crack resistance of different finishing methods, three full-scale two-story single span steel frame embedded ALC plate low cyclic reciprocating load tests were designed and carried out. By comparing the failure evolution process of plate with different connection methods, the failure mode of embedded autoclaved lightweight concrete plate is obtained, and the influence of connection methods on the crack resistance of ALC plate and the crack resistance of different finishing methods are analyzed. The results show that the main failure mode of the embedded ALC plate is the cracking of the plate connector; The built-in anchor connection has better crack resistance than hook bolt connection and sliding bolt connection; The finish at the joint between plate and steel frame is weak in crack resistance, the finish at the joint of plate has good crack resistance, and the crack resistance of two-component sealant is better than single component sealant.更多还原
