FRP composite materials (Fiber Reinforced Plastic, referred FRP) is a high-strength light-weight , low-power construction of new materials with high toughness , corrosion and fatigue resistance , excellent performance , are gradually replacing some traditional materials, more and more applications in the building structure. Thus, for the FRP plate and column buckling of FRP is necessary, this paper analyzes FRP components were as follows : This article describes the characteristics of FRP materials , including its production process and a variety of excellent performance , summed up the domestic and international trends and FRP structures in a wide range of building applications , as well as the stability of FRP composite laminate analysis of the basic methods and theoretical results , focusing on the FRP plate and column buckling carried out a detailed analysis , the main work is as follows : Based on the stability theory and linear and nonlinear finite element method to MSC software as a working platform , using thin Shell FRP plate rectangular plate unit to establish the finite element model , the results validate the reliability of buckling analysis , based on the different forms of boundary conditions and loads FRP plate buckling analysis were obtained FRP plate buckling general rule ; explores shaped , box , pole -section FRP local stability ; under ideal conditions and considering initial bending conditions, the box- shaped cross-section and FRP pillars overall stability analysis, consider different slenderness ratio and three different material parameters obtained FRP overall stability pillar of the law. Finally , the article summarizes the content of the study and buckling of FRP components were discussed.
