大柱网现浇混凝土框架空心大板结构的试验研究

根据工程实例中柱网8．4m×8．0m×2（跨）现浇混凝土框架空心大板结构做了1：1的模型试验，试验结果表明：该楼盖承载力大，安全储备高，内力符合“归并法”所具有的变化规律，用ANSYS中SOLID65单元对此空心楼盖进行仿真分析，结果表明ANSYS值与试验值比较吻合。通过试验研究为此类楼盖应用于大柱网多层建筑现浇混凝土框架空心大板结构及大柱网高层建筑现浇混凝土空心大板框架一剪力墙结构提供了实验数据。并再次验证了“归并法”的正确性及科学性。

Experimental Research on Large Column Grid Cast-In-Situ Concrete Frame Hollow Large Slab Structure

A 1：1 model experiment of cast-in--situ concrete frame hollow large slab structure was made in accordance with a factual engineering with column grid of 8.4 m×8.0m×2 （span）. The experimental result showed the high load-carrying capacity and high safety factor of such floor and the conformity of its internal force to the variation rule of ＂merger method＂. The imitation analysis of such hollow floor by the element SOLID65 of ANSYS indicated that the value of ANSYS was very close to that of the experiment. The experimental research provided experiment data for the application of such floor to both multi-storey buildings with large column grid structure and tall buildings with large column grid frame ＆ shearwall structure, and also proved the ＂merger method＂ to be scientific and accurate.
