钢----砼组合楼盖结构空间作用的理论和试验研究

Experimental study is conducted on the space action of steel frame with composite steel-concrete floors. One model test, space frame with four-story, five plane frames and single span, is completed. More than twenty types of loading are applied on the space fame. Theoretical analyses and numerical analyses are carried out. Analytical method is proposed on the account of space action from the space frame with composite steel-concrete floors. Concerned parameters are discussed on the contribution to the space action of frame from composite steel-concrete floors. A simplified model is proposed for calculating the space action of frames with composite floors. The research results of the program are valuable to the design of space frame of composite floors with account of space action.
