Nonlinear stability and design of prestressed stayed columns in fire considering non-uniform temperature distribution

K Wu, Z Xing, H Li - Journal of Building Engineering, 2023 - Elsevier
Prestressed stayed columns are vulnerable to fire due to material weakening. The fire
behaviour of the stayed columns is investigated with non-uniform temperature distributions …

Fire Behavior of Prestressed Stayed Columns: Critical Temperature and Mode Transition

K Wu, Z Xing, G Li, H Chang - Journal of Structural Engineering, 2024 - ascelibrary.org
Prestressed stayed columns are vulnerable to the stiffness loss in fire. This study aims to
reveal the fire resistance and failure behavior of this system. Based on the theoretical …

A nonlinear FE formulation for elastic buckling and post-buckling analysis of pre-stressed stayed columns with bonded/un-bonded cable stays

F Zhang, MY Kim - Thin-Walled Structures, 2024 - Elsevier
This study intends to investigate elastic buckling and post-buckling behaviors of pre-
stressed (PS) stayed columns with single and triple cross-arms using a nonlinear FEM. To …
