| 中文摘要: |
| 对叠合式双向板和普通全现浇双向板进行加载试验。实验分为三组，其中一组为全现浇，另二组为叠合板，研究四边简支叠合式双向板在均布荷载作用下的荷载-应变的变化规律。试验结果表明,在加载相同情况下，叠合板与现浇板的荷载—应变曲线很接近，说明叠合板具有较明显的双向板特性。同时，叠合式双向板在极限荷载标准值下的钢筋应力很小，远小于钢筋的屈服强度。因此，叠合板的配筋按现浇双向板配筋理论计算，是满足规范设计要求的。 |
| 英文摘要: |
| It was focused on the loading experiment of composite two-way slab steel and ordinary cast-in-situ two-way slab. There were three groups of experiments, one cast-in-situ, two composite. The stress changing rule of four edges simply supported composite type two-way slab under uniform load test were studied. The results show that the figure lines of composite and cast-in-situ was close under the same load cases. It indicates that composite slab has a two-way characteristic. Meanwhile, under the ultimate load standard, superposition type two-way slab under the reinforcement stress is small, far less than the yield strength of steel. As a result, the superimposed slab reinforcement calculated by cast-in-situ two-way slab reinforcement theory, meets the design specification. |
