Simplified Calculation Formula on Sliding Snow Load on Roof

摘要:

利用屋面滑移雪荷载的模拟方法，基于屋盖积雪层能量、质量平衡方程，对我国几个代表性地区的屋面滑移雪荷载进行了模拟，提出了我国南北地区滑移雪荷载系数的简化计算公式，并将简化计算的结果与一些国家规范方法的结果进行了比较.

Abstract:

The building roof snowmelt model, which was based on the previous mass and energy balance models, was adopted to compute the sliding snow loads on roofs in several typical countries. A simplified calculation formula that could compute the coefficient of sliding snow load was given. And a comparative study was made between the results from the simplified calculation formula and those from the load codes of some countries.
