Buckling Analysis of Pultruded Fiber Reinforced Polymer Plastic Plate: Application of Simplified Buckling Analysis

Abstract:

The pultruded fiber reinforced polymer plastic (PFRP) is one of the most actively studied materials for structural member in construction industries. In this study, a buckling analysis of PFRP plate is conducted by two analysis methods. First, a buckling strength of PFRP plate is calculated by the exact orthotropic plate buckling analysis. Second, simplified buckling analysis for PFRP plate is conducted by using approximate orthotropic material properties. The approximate orthotropic material properties are geometric mean value of longitudinal and transverse material properties of original PFRP plate. As a result of buckling analysis, buckling strength of PFRP plate for each analysis method can be obtained. From the comparison between these results, advantages and disadvantages of each analysis method are discussed. In addition, it is also discussed whether the simplified buckling analysis method for PFRP plate is applicable for the design.
