波动风效应对金属屋面系统抗风及防水性能的影响

Fluctuating Wind Effect on the Wind Uplift Resistance and Waterproofing Performance of the Metal Roof System

在提出金属屋面系统内外风荷载计算取值的基础上,指出波动风效应是影响金属屋面系统结构抗风及防水抗渗能力的主要因素,只有对金属屋面系统材料、板型及构造进行合理的设计及其抗风性能进行测试,才能保障金属屋面系统结构抗风和防水的质量。

Based on the calculation and evaluation of the internal and external wind load, this article points out that the fluctuating wind effect is the main factor to influence the wind uplift resistance and waterproofing performance of the metal roofing system. The engineering quality of roofing system could only be guaranteed by rational design of the material, plate type and structure of the metal roof as well as its wind uplift resistance test.
