中文摘要：

为了研究钢一混凝土深肋组合扁梁楼盖的动力特性以及在动力荷载作用下的承载特性，构造了1×2跨双层深肋组合扁梁楼盖试件，并通过试验方法对试验楼盖的自振频率、空间性能以及不同加速度峰值的地震波作用下的拟动力承载性能进行了量测和研究。试验得到了试件的横、竖向前两阶自振频率以及水平拟动力加载位移时程曲线及滞回曲线，相关结果表明试件具有较好的空间性能，当加速度峰值为0．05g和0．1g时试件基本处于弹性阶段，当加速度峰值为0．2g时结构处于微开裂阶段。另外，试验结果能为进一步深入研究深肋组合扁梁楼盖的承载性能起到一定的借鉴作用。

英文摘要：

This paper presents an experimental study on a full-scale two-storey, two-bay by one-bay steel-concrete composite slim floor that was subjected to horizontal pseudo-dynamic loadings. Tests on the natural frequency and membrane behavior of the specimen have been conducted. In addition, the time-history load-displacement curves and hysteretic curves obtained from pseudo-dynamic loading test have been specified. Based on the test results, the specimen has a good membrane behavior and remained elastic under the loading cases of amax= 0. 05g and amax=0. 10g, but started to crack slightly under the loading case of amax=0.20g. The test results can provide a reference for further researches.
