压型钢板–ECC水泥纤维板组合楼面板的动力特性试验研究

Experimental Study on Dynamic Characteristics of Profiled Steel Sheet-ECC Board Composite Floor Panels

摘要: 提出了一种新型装配式组合楼板，该组合楼板以自攻螺栓为剪力栓钉，压型钢板、ECC水泥纤维板分别作为受拉及受压单元，压型钢板包括闭口型截面和开口型截面两种类型。在详细解析新型楼板构造的基础上，对新型楼板的动力特性进行了试验研究，研究表明，新型装配式组合楼板基频最小值为20.35 Hz，能够满足楼板面舒适度的基本要求。研究结果为新型楼板的工程应用提供了依据。

Abstract: A new type of prefabricated composite floor slab was proposed, in which self-tapping screws were used as shear studs, and corrugated steel sheets and ECC cement fiber boards were respectively adopted as tensile and compressive units. The profiled steel sheets include two types: closed-section and open-section. Based on a detailed analysis of the structure of the new floor slab, an experimental study on the dynamic characteristics of the new floor slab was conducted. The research shows that the minimum fundamental frequency of the prefabricated composite floor slab is 20.35 Hz, which can meet the basic requirements of floor surface comfort, providing a basis for the engineering application of the new floor slab.
