FRP在空间结构中的应用和受力性能分析

Behavior analysis and applications of FRP in spatial structure

纤维聚合物(Fiber Reinforced Polymer,以下简称FRP)在空间结构中的应用,是国内外土木工程界的前沿课题之一.FRP的自重轻、耐腐蚀和材料可设计性的优点,奠定了其在大跨度空间结构中应用的基础.在国内外相关资料的基础上,综述了FRP管(杆)、FRP层合板和FRP轻质屋盖在空间结构中的工程应用和研究现状,并对采用GFRP复合材料层合板的板锥网壳结构受力性能进行了分析,分析表明:板锥网壳结构采用GFRP复合材料新型板材具有更大的优越性;最后提出了需进一步研究的问题和展望.

The application of fiber reinforced polymer （FRP） rebar to spatial structure is one of the topics in forward position at home and abroad. The properties of FRP rebar, such as high tensile strength, light weight, strong resistance to corrosion and fatigue, material designability and weight reduction and so on, pave the way to its application to spatial structure. Based on the relevant studies at home and abroad, the summary of application and research of FRP, such as CFRP poles, composite laminated plate and FRP light roof, rebar to spatial structure are introduced in the paper. The static characteristics for plate-cone reticulated shell with GFRP composite material plates were analyzed in the paper. It is shown that the plate-cone reticulated shell with GFRP composite material plates is more advantageous. Finally, the prospects and some problems needed to be further researched are put forward.
