摘要
根据调查分析,建立单层双坡屋面建筑和两层双坡屋顶建筑的数值模型,模拟在主导风向下建筑风荷载的影响。通过与现有建筑结构规范的比较,得出了低矮房屋的风压分布系数的最大正负压系数,并指出屋顶负压区分布面积较大。
According to the analysis of the investigation,the paper establishes the the numeric models of the single-layer double-slope roof building and the double-layer and double-slope roof buildings,stimulates the influence of the building wind loading under the dominated wind direction,achieves the maximum positive and negative pressure coefficient of the wind pressure distribution coefficient of the low buildings,compared with the current architectural structure regulation,and points out the distribution coverage of the negative area of the roof is larger,so as to provide the direction for the engineering design.
