EXPERIMENTAL RESEARCH ON THE MECHANICAL PROPERTIES OF SHORT DOUBLE-SKIN MULTI-CAVITY COMPOSITE WALL WITH STEEL TRUSS UNDER AXIAL COMPRESSION
-
摘要: 对14个桁架式多腔体钢板组合剪力墙短墙试件进行了轴压试验，研究腔体端柱、钢筋桁架节点间距以及钢筋直径对试件的破坏形态、承载力和延性的影响规律。结果表明：钢筋直径、钢筋桁架节点间距以及端柱的不同形式，对试件的极限承载力与屈服强度具有一定的影响，内部桁架增强了钢板与混凝土之间的协同工作能力，使得试件的极限承载力及屈服强度均有所提高。

Abstract: 14 short double-skin multi-cavity composite walls with steel truss were tested under axial compression. The influence of the end column of the cavity, the joints spacing of the steel bar truss and the diameter of the steel bar on the failure mode, bearing capacity and ductility of the shear walls were studied. The results showed that the ultimate bearing capacity and yield strength of the specimens were affected to some extent by the diameter of the steel bars, the joints spacing of the steel bar and the different forms of the end columns. The role of internal truss could enhance the cooperative working capacity between steel plate and concrete, and improve the ultimate bearing capacity and yield strength of the specimen. -
