摘要

研究目的:铁路无站台柱雨棚为四周开敞建筑,通常采用钢结构形式,为风敏感结构,本文通过对 14 个无站台柱雨棚风洞试验的结果进行分析,归纳总结其共性特征,并与现行《建筑结构荷载规范》( GB 50009—2001) 进行对比分析,得出无站台柱雨棚风荷载体型系数的一些分布规律,为结构计算提供参考。
研究结论:( 1) 铁路无站台柱雨棚风压系数介于0.1 ~0.9 之间,风吸系数介于 -0.3 ~ -2.0 之间; (2) 试验得出的风压体型系数一般小于《 建筑结构荷载规范》( GB 50009—2001) 类似参考值,而风吸体型系数两者较为接近; (3) 檐口、洞口处的风荷载具有放大效应。

Abstract

Research purposes:The No - platform - column Canopy is the open wide building,and steel structure.This paper analyses the results of 14 wind tunnel tests of t No - platform - column Canopy and concludes the commonness.Then contrast with the " Load Code for the Design of Building Structures " ( GB 50009 - 2001) . This paper educes some distributing of the wind load figuration coefficients of No - platform - column Canopy . The disciplinarian provide some reference for the structure calculation.
Research conclusions:(1) The wind load pressure figuration coefficients of the No - platform - column Canopy is between 0.1 ~ 0.9,the wind load suck figuration coefficients is between - 0.3 ~ - 2.0; (2) The wind load pressure figuration coefficients of the test is smaller to the " Load Code for the Design of Building Structures" ( GB 50009 - 2001)and the wind load suck figuration coefficients is bigger; (3) The wind load figuration coefficients enlarges on the cornice and hole.
