摘要：
Advanced composite structural shapes (beams and columns) have been shown to provide potential applications in bridges and structures. This study is concerned with the development of a step-by-step simplified design guidelines for fiber reinforced plastic (FRP) beams, accounting for bending and shear deformation, local/global buckling, and ultimate material failure. The design equations are developed based on a combined experimental and analytical study of eight representative beams, and are expressed in terms of panel apparent moduli and strengths and beam stiffness coefficients and geometry. The design parameters are verified by testing these eight sections, and the design equations are validated by the testing data. Carpet Plots for panel apparent moduli are provided for facilitating design of pultruded FRP shapes. The information provided can assist engineers and manufacturers to design their products and also serve the agencies to develop "product-acceptance criteria" for FRP beams.
