中文摘要	钢网构架混凝土复合结构是一种新型组合结构住宅体系,它由工厂预制的钢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。钢骨架由纵向的开孔冷弯薄壁型钢、横向的钢拉条以及充当永久模板的钢模网构成,在现场拼装后浇入混凝土。为研究钢网构架复合结构多层房屋的抗震性能,建造一栋三层足尺结构模型,对其进行水平反复拟静力试验,模拟六层住宅结构在地震作用下的反应,研究此类结构的受力性能和破坏特征。试验表明:此结构具有较高的承载能力和延性,能够满足抗震设防烈度8度的要求;模型中的连接构造措施能够保证结构的整体性,其中层间连接构造对结构整体性能有较大影响,可通过改善构造措施进一步提高整体结构的承载力;复合结构构件中钢骨架与混凝土结合良好,能够共同工作。; CTSRC(cold-formed thin-walled steel reinforced concrete) structure is a new composite structural system for residential buildings.A CTSRC structure consists of walls and floors which are made of the prefabricated steel skeleton and the infill of concrete.Steel skeletons are composed of cold-formed thin-walled steel studs with web opening in the longitudinal direction,steel strips in transversal and the permanent formwork of steel meshes,which are assembled in site before casting concrete.To investigate the seismic behavior of CTSRC structure buildings,a 3-story full scale model was constructed and tested under low cyclic lateral loading,which simulated the seismic response of a 6-story structure.Mechanical performance and failure mode of CTSRC structures were obtained in the test.Test results show that CTSRC structure has sufficient load carrying capacity and high ductility required for seismic intensity of 8.0 per Chinese design codes.It is validated that the connection details in the structural model are effective to ensure the integrity of structures.It is found that the inter-story connection of walls significantly affects the behavior of CTSRC structures.The load carrying capacity can be increased by improving the connection configuration.The test also shows a good composite effect between the steel skeleton and concrete in the CTSRC structure.; 长江学者和创新团队发展计划资助项目(IRT00736)
