摘要:
为解决结构设计时开洞口圆形煤仓表面无法确定荷载分布系数问题,使用计算流体力学软件研究了开洞口煤仓不同跨度下风向角、积雪厚度及矢跨比变化下屋面积雪不均匀分布情况,提出了针对此种特殊结构的屋面积雪值拟合公式。研究结果表明:此公式拟合准确度高,屋面积雪值随风向角和积雪厚度增大而变大,风向角对积雪值影响极大,矢跨比影响下屋面积雪值变化较为复杂,且风向角和矢跨比2种参数相互影响,不应单一考虑矢跨比对球壳屋面积雪值的影响。
Abstract:
In order to solve the problem that the load distribution coefficient on the surface of opening circular coal bunker cannot be determined in the structural design, the uneven distribution of snow on the roof of opening coal bunker with different spans under the variation of wind direction angle, snow cover thickness and risespan ratio was studied by using the computational fluid dynamics software, and the fitting formula of snow cover value on the roof aiming at this type of specific structure was put forward. The results showed that the fitting accuracy of this formula was high. The snow cover value on the roof increased with the increase of wind direction angle and snow cover thickness, of which the wind direction angle had a greater influence. The variation of snow cover value on the roof affected by the risespan ratio was more complicated, and the wind direction angle had an interaction with the risespan ratio, so the influence of risespan ratio on the snow cover value of the spherical shell roof should not be considered alone.
