摘要

摘要: 三心圆柱面网壳封闭货棚是一种典型的风敏感结构,风荷载是结构设计时的控制荷载之一。以某综合码头工程中的三座三心圆柱面网壳封闭货棚为背景,对影响封闭货棚风荷载的多种因素进行风洞试验和计算分析。研究了货棚顶部通风屋脊、门窗开合情况、三座货棚相互干扰、风速风向折减等情况对封闭货棚风荷载的影响,比较了根据风洞试验结果、荷载规范和相关文献中的风荷载设计的封闭货棚的计算结果。研究发现:顶部通风屋脊、门窗开合情况、三座货棚相互干扰、风速风向折减等情况均对风洞试验结果有较大影响,根据荷载规范和相关文献风荷载对封闭货棚进行结构设计存在安全隐患,此类大跨度封闭货棚在施工图设计前应进行风洞试验研究,且在进行风洞试验时应考虑和正确反映货棚实际存在的多种工况。

Abstract: Three-center cylindrical latticed shell closed cargo shed is a typical wind-sensitive structure, and wind load is one of the control loads in structural design. Based on the background of three three-center cylindrical latticed shell closed cargo sheds in a comprehensive wharf project, wind tunnel tests and numerical analysis on various factors affecting wind load of closed sheds were carried out. The influence of the ventilation roof, the opening and closing of doors and windows, the interference between three sheds, and the wind speed reduction related to wind directions on the wind load of the closed cargo shed was studied, the calculation results of closed cargo sheds designed by the wind load in wind tunnel test results, load codes and related literature are compared. Through the research, it is found that the ventilation roof, the opening and closing of doors and windows, the interference between three sheds, and the wind speed reduction related to wind directions had great influence on the wind tunnel test results, there were potential safety hazards in the structural design of closed sheds by the wind load in load codes and related literatures, the wind tunnel test of this kind of long-span closed sheds should be conducted before the detailed design, and the various actual working conditions of the sheds should be taken into account and correctly reflected during the wind tunnel test.
