【摘要】 本文在分析现浇钢筋混凝土空心板无梁楼盖和扁梁的力学性能的基础上,推荐了一种新型的楼盖体系:现浇钢筋混凝土扁梁—空心板楼盖。首先,本文以已有理论和试验为基础,分析了两种主要的现浇钢筋混凝土空心板楼盖:现浇钢筋混凝土空腹夹层板楼盖和现浇钢筋混凝土肋梁式空心板楼盖,并得出结论:空心板在竖向荷载作用下的力学性能和实心板是相似的,可以采用与实心板相同的设计方法,但应加强构造措施。其次,对于钢筋混凝土扁梁,本文着重研究了它的节点受力性能和破坏机理,指出设计中应注意其不同于普通框架节点的地方:宽梁的受扭破坏和节点外核心区的剪切破坏,并提供了具体的设计方法和构造要求。最后,本文以具体的工程事例,演示了这种新型体系的设计方法。更多还原

【Abstract】 As a new horizontal type of diaphragm in a structuralframe, in-site reinforced concrete hollow slab supported onwide-flat beams was introduced based on the analysis ofmechanics of reinforced concrete hollow slabs and wide-flatbeams in this thesis.Firstly, two kinds of reinforced concrete hollow slabs,which were vierended-sandwich-plates and ribbed hollow slabs,were studied on the base of theories and tests and conclusionswere drawn that the behavior of hollow slabs subjected tovertical loads was the same the as normal slabs, but detailsmust be emphasized.Secondly, joints formed by wide-flat beams and columnswere analyzed and the difference of mechanics betweenwide-flat beams and normal beams were shown, and failures ofwide-flat beams subjected to torques and failures ofouter-joints subjected to shears should be noticed.Finally, the design methods of reinforced concrete hollowslabs and wide-flat beams were provided with an application.更多还原
