Fiber-Reinforced Plastic Composite Beam Stability And Load And Resistance Factor Design Approach, Mojtaba B. Sirjani

Civil & Environmental Engineering Theses & Dissertations

Fiber Reinforced Plastic (FRP) structural members are rapidly gaining impetus in civil engineering applications. Also, thin-walled open beams with I-shaped, channel, and other types of sections are of practical importance to both structural analysts and designers. This dissertation presents the outcome of a detailed experimental and theoretical investigation of the strength and stability of FRP composite beams. Three- and four-point loading tests are conducted on FRP I- and channel section beams. The behavior of these beams is studied under gradually increasing static loads up to the maximum load-carrying capacity corresponding to either material cracking or flexural-torsional instability. First, the theoretical …
