Composite Beam-Columns Performance Based on Nonlinear Fiber and Finite Element Analysis
Abstract eng: Results obtained from nonlinear fiber analyses (FA) and finite element analyses (FEA) for concrete-filled-tubes (CFT) are discussed. These analyses, based on the assumed stress-strain material curves, member slenderness, initial imperfections, and material and geometric nonlinearities, etc., were aimed at assessing primarily the overall behavior on these structural elements as a prelude to a large full-scale testing program. Some results are compared with those obtained from AISC (2005) or analytical equations published in the literature. Fiber and finite based results show a compatible correlation with the expected element behavior, which is also captured in the current 2005 AISC Specifications and 2005 AISC Seismic Provisions.
