从实际项目案例看GB 50009—2012《建筑结构荷载规范》与FM抗风揭设计的不同

Look at the Difference Between GB 50009—2012 “Load Code for the Design of Building Structures” and the Design of FM Wind Uplift Resistance from Actual Project Cases

某单层屋面抗风揭设计时,根据实际风压、风速、地形系数、阵风系数等因素计算设计荷载值,选用相同高分子卷材及紧固件,按照GB 50009—2012《建筑结构荷载规范》及FM 1-28风荷载规定这两种规范文件的不同逻辑思路确定屋面紧固件排布,并进行了比较。同时介绍了该屋面采用1.2 mm厚聚酯纤维内增强型PVC防水卷材进行无穿孔机械固定的施工工艺。

As per actual wind pressure, wind speed, topographie coefficient, gustiness factors el cetera, the wind uplift resistance design of some single ply roof employs the same polymer membrane and fasteners. It arranges the fasteners respectively according to the different logic thinking of GB 50009--2012 ＂Load code for the design of building structures＂ and FM 1-28 wind load regulations and compares the two methods. Meanwhile, the article introduces the construction technology of non-perforated mechanical thstening by polyester reinforced PVC waterproofing membrane of 1.2 mm thiekness.
