摘要:
为研究双钢板-混凝土组合剪力墙结构的耐火性能,对 3榀采用不同剪力件连接(螺栓连接、栓钉连接、栓钉和剪力杆组合连接)的双钢板-混凝土组合剪力墙进行了轴压力和单面ISO-834标准升温作用下的耐火性能试验,得到这种新型组合剪力墙结构在火灾下的温度场分布、轴向变形及破坏模式,并就不同剪力连接件对组合剪力墙耐火性能的影响进行了分析和比较.结果表明,剪力连接件能够保证钢板与混凝土共同工作;采用不同剪力连接件连接的组合剪力墙在火灾下的破坏模式是相同的,但不同剪力件对组合剪力墙耐火性能的影响不同,采用螺栓连接的组合剪力墙的耐火极限最短,采用栓钉和剪力杆组合连接的剪力墙耐火极限最长.
Abstract:
In order to investigate the fire performance of the concrete filled double-steel-plate(CFDSP)composite wall, three specimens with different shear connectors(bolted connection, stud connection, stud and shear rod connection)were tested under the axial compressive force and one-side ISO-834 standard fire to obtain the temperature distribution, the axial deformation, and the failure modes of the CFDSP composite walls. And the influences of the different shear connectors on the fire performance of the CFDSP composite walls were analyzed and compared. The results show that connectors can ensure the interaction work between the double-steel-plate and the infilled concrete. The failure modes of the CFDSP composite walls with different shear connectors are the same. The different shear connectors result in different effects of the fire performance of the CFDSP composite walls. The fire endurance of the CFDSP composite wall with the bolted connector is the shortest, while that of the CFDSP composite wall with the stud and shear rod connector is the longest.
