Civil & Environmental Engineering Theses & Dissertations

This thesis presents the outcome of a study of the behavior and strength of pultruded glass fiber reinforced polymer (FRP) I-section columns including uniaxial and biaxial applied bending moments. Also included in the study is a critical assessment of ASCE-LRFD Pre-standard for pultruded FRP structures in view of the rigorous analysis presented herein. The theoretical solution is based on a system of three coupled differential equations of equilibrium combined with pinned flexural and torsional boundary conditions. Effects of induced warping due to second-order terms as well as initial out-of-straightness are accounted-for in the governing differential equations. Detailed investigations into the …
