Prestressed stayed columns are vulnerable to the stiffness loss in fire. This study aims reveal fire resistance and failure behavior of this system. Based on theoretical optimum prestress, prestressed is investigated using transient state analysis within ABAQUS version 6.14.4 with both uniform nonuniform temperature distributions considered. Results show that columns' approximate above 600°C, system usually fails stay slackening sometimes retension. If reflective symmetric buckling mode...
With the growing use of stainless steel in construction and offshore industries, there is an increasing interest need to study performance structures at elevated temperatures. The behavior design I-section beam-columns fire investigated this paper, addressing a scarcity previous research on topic. Finite element (FE) models beam-columns, able replicate their response temperatures, are created validated; validated then used perform parametric studies generate extensive benchmark structural...
Both the geometric and material nonlinearities are significant in prestressed stainless steel stayed columns due to their highly slender configuration plasticity. The interactive buckling is investigated numerically with these two considered. Compared carbon dominated by elastic post-buckling behaviour, dual-nonlinearity interaction found for first time, this can reduce significance of buckling. Moreover, it clearly identified that there exist types representative phenomena especially cases...
