Yanchun Yu, Ziyan Zhao, Zhonghao Zhang, Weidong Chen, Yi Zhong, Yongxin An
TL;DR
This study evaluates the reliability of the overall structure of a submerged radial steel gate under various loads, finding it safe with key factors affecting displacement and stress.
Contribution
The study introduces a comprehensive reliability analysis of the overall submerged radial steel gate structure considering multiple dynamic load combinations.
Findings
Maximum stress and displacement values meet design code limits, with maximum stress at the support hinge.
The structure is safe at a 95% confidence level when considering random variables in load combinations and material parameters.
Hydrodynamic pressure and elastic modulus significantly influence displacement and stress calculations.
Abstract
The safety assessment of steel gate structures holds significant social importance and economic advantages. The safety of steel gate structure is influenced by numerous random factors, so it is necessary to carry out the reliability analysis of steel gate structure. Currently, research on the reliability of steel gate structures predominantly focuses on individual components, cross-sections, or localized areas, and there are relatively few studies on the reliability of the overall structure of the steel gate. Furthermore, most of the studies only consider the role of hydrostatic pressure load, often underestimating the impact of other dynamic load combinations. Therefore, this study calculates the strength and stiffness of the overall submerged radial steel gate structure under various loading conditions, including hydrostatic pressure, hydrodynamic pressure and sediment pressure.…
