| 摘 要： | 钢网构架混凝土复合结构体系(CTSRC)是一种新型结构体系,它由工厂预制的钢构骨架和现场浇筑其中的混凝土构成墙体和楼板,从而形成整体结构。为研究钢网构架混凝土复合结构楼板的受力性能并确定设计计算方法,进行了6块单向楼板的静载试验破坏;基于试验结果提出一种等效钢筋混凝土梁的计算方法和一种截面条带计算方法,进行了分析比较;建议采用基于截面条带法的承载力计算方法,并编写了计算程序。最后,对实际结构中此新型楼板体系进行堆载试验,获得实际结构中楼板的受力性能。试验结果表明:建议的设计计算方法可行,且此楼板具有较高的承载力安全储备。

| Abstract: | Cold-formed thin-wall steel reinforced concrete(CTSRC) structure is an emerging composite structure for residential buildings.A CTSRC structure has integrated walls and floors made of a prefabricated steel skeleton and in-situ infill of concrete.The mechanical behavior and strengths of 6 CTSRC slab specimens were tested to failure with static loads.Two calculation approaches were then developed based on an equivalent reinforced concrete beam and a stripped section based on the tests.Comparison with the expe... |
