摘要:
通过对用于多层住宅的一榀新型复合结构模型在竖向荷载作用下的试验,研究了复合结构在正常使用阶段和承载力极限状态时梁柱及支撑的各截面应力、裂缝、变形和破坏形态.结果表明,一榀五层复合结构,在梁柱截面为250 mm×250 mm、支撑截面为120 mm×120 mm、承载面积为4.2 m×4.2 m的情况下,荷载达到一般住宅竖向荷载标准值及设计值时,梁的裂缝和挠度远小于混凝土规范限值.复合结构在竖向荷载作用下的破坏形态为梁铰机构体系;并建议梁的高度取实际跨度的1/14～1/10.
Abstract:
Through the test of a new composite structure model for multi-storey housing under vertical loading, the stress, cracks, deformation and failure patterns of beams, columns and supports during the normal service stage and bearing capacity limit state of composite structure were studied. The results show that when the beam and column cross-section is 250 mm×250 mm, the support cross-section is 120 mm×120 mm, and the bearing area is 4.2 m× 4.2 m, the cracks and deflections of the beams and columns are much smaller than the concrete specification limits when the load reaches the standard value and design value of the general residential vertical load. The failure form of the composite structure under vertical load is the beam hinge mechanism system. And it is recommended that the height of the beam should be 1/14~1/10 of the actual span.
