张弦梁-混凝土板组合楼盖结构是一种采用张弦梁支承混凝土板的新型楼盖结构形式,河北师范大学体育馆二层楼盖是该结构形式在国内工程中的首次应用。以河北师范大学体育馆为工程背景,对东侧区域张弦梁-混凝土板组合楼盖结构的设计进行了介绍,针对大跨度张弦梁-混凝土板组合楼盖结构的力学性能进行了数值模拟分析,明确了张弦梁-混凝土板组合楼盖结构的受力机理,总结归纳了该结构体系在工程应用中应注意的关键技术问题,即预应力设计、张弦梁与混凝土板的协同工作、施工过程中张弦梁滑动端水平位移以及舒适度分析。
Cable supported beam structure-concrete slab composite floor system is a new type of floor structural system which uses cable supported beam structure to support concrete slab,and the application of this structure for the first time in our country is the second floor of Hebei Normal University gymnasium. Based on Hebei Normal University gymnasium,a detailed introduction of the design process of the cable supported beam structure-concrete slab composite floor system in east area was provided,and numerical simulation analysis was carried out aiming at the illumination of mechanical properties of the structure. The load transfer mechanism of the cable supported beam structure-concrete slab composite floor system was clear,and key technological problems in application of the structure were summarized including design of pre-stress,cooperative work of cable supported beam structure and concrete slab,horizontal displacement of sliding support of beam string structure in construction process and human comfort analysis.
