摘要

摘要: 通过玻璃纤维增强复合材料(GFRP)拉挤空心板的静载试验，研究了其受力性能、变形、应力分布和破坏特征，并与有限元数值模拟的结果进行了对比。根据试验和分析结果，针对FRP材料各向异性、拉压不同的特点，提出了按受力状态划分截面取加权平均来计算等效截面刚度的简化方法。还根据板中应变分布与发展的特点，对构件的局部屈曲和强度破坏两种破坏机理进行了分析，为FRP空心板的设计与应用提供了依据。

Abstract: Fiber reinforced polymer(FRP) hollow slab is an innovated structural element applied to structure engineering recently.It has a considerable future application in civil engineering due to its favorable properties, such as light weight, corrosion resistance and rapid construction.It can be used in industrial mill buildings, floors, footbridges, bridges and their enclosures.The behavior of simple supported pultruded glass fiber reinforced polymer(GFRP) hollow slab is studied through a static loading test and finite element analysis.The deflection, the distribution of strain and the ultimate failure of the slab are analyzed.Base on the results, a simplified approach to determine the equivalent stiffness of FRP hollow slab that is the area-weighted mean depended on the section characteristic is presented.It considers the anisotropy and the different elastic modules of tension, bend and compression of FRP.The local buckling failure mode and the strength failure mode of the FRP deck are simulated, which provides a basis for the design and application of FRP hollow slab.
