集中荷载作用下钢—混凝土预制板组合梁的受弯性能与组合效应

The composite action and carrying capacities of the composite steel-FDPCP beams under concentrated loads

根据3根集中荷载作用下钢—混凝土预制板组合简支梁的试验结果,从组合梁的荷载—滑移、荷载—组合梁跨中全截面应变及荷载—挠度等方面对钢—混凝土预制板组合梁进行了试验分析,同时结合现有普通组合梁的设计理论,推导出这种新型组合结构的设计公式。

Based on the test results of three simplysupported composite steel-FDPCP（ Full-Depth Precast Concrete Panels） beams under concentrated loads, this paper analyse their behaviors of carrying capacities and composite action from the relations of load-sllp, load- deflection and load-strain distribution in the section of the composite steel-FDPCP beams, and combine the existing design theories of the common composite beams, the author detrude the design formulas of the new style structure.
