中文摘要: |
针对两种不同的双向板,即叠合式双向板和普通全现浇双向板进行施加竖向荷载试验。共做四组双向板试验,其中一块为全现浇,另三块为叠合板,研究四边简支叠合式双向板在均布荷载作用下的挠度变化规律。试验结果表明,在板开裂之前普通双向板和两拼式叠合板的荷载-挠度曲线基本相同,可以直接使用弹性薄板理论[8]计算两拼式叠合板的挠度,且进入弹塑性阶段后全现浇板的刚度退化较快。 |

Results from the two different two-way slab, composite two-way slab and ordinary two-way slab be applied vertical load test. A total of four experimental groups, including one for the ordinary two-way slab, the other three for the composite two-way slab. Research Simply Supported on Four Sides composite two-way slab deflection variation in the uniform loads. The results showed that before the board cracking ordinary two-way slab and ordinary two-way slab load - deflection curve is basically the same calculation ordinary two-way slab deflection elastic plate theory can be used directly, and into the ordinary two elastic-plastic stage -way slab stiffness degradation faster. |
