摘要:
分析基于构件计算屋盖结构损伤率的计算方法,建立功能函数,并对用于功能函数的结构构件承载力进行计算.研究瓦片掀翻和椽条破坏两种破坏形式下的屋盖的损伤率,和风向角、高宽比、坡角对损伤率的影响作用.研究结果表明:圆形土楼屋盖的弹性极限风速约为20 m·s-1,塑性极限风速约为45 m·s-1,使用功能极限风速约为30 m·s-1;屋面坡角、高宽比的增大均会增大屋盖结构的损伤率;二次损伤率很大,基本上达到一次损伤率的一半.此外,外挑檐和屋脊外的灾损
Abstract:
Based on the method to evaluate the damage rate of roof structure by analyzing the roof structural member, a performance function was established to calculate the bearing capacity of structural members. The roof structure damage rate was studied under two conditions: damage by tiles’ overturning and rafters’ breaking. The effects of wind angle, the ratio of height to width and slope angle on the damage rate were also studied. The research shows: the elastic limit wind speed on round Tulou roof is about 20 m·s-1, the plastic limit wind speed is about 45 m·s-1, and the extreme wind speed for the function usage is about 30 m·s-1; the roof structure damage rate increases with the increase of the roof slope angle and the ratio of height to width; the secondary damage rate is approximately as high as the half of the first damage rate. The disaster losses of the outer cornice and the roof outside are the most severe in the entire roof structure.
