基于台风过程的低矮建筑屋面损伤研究
Research on Damage to Roofs in Low-Rise Buildings Based on Typhoon Courses
摘要
Abstract
In order to consider the impacts of wind speed and direction on building damages during the typhoon course,a common low-rise building in coastal areas was taken as the research object.This paper combined the probability distribution of wind extreme pressure coefficient on the roof obtained from a wind tunnel test and the typhoons generated by the Yan Meng wind field model to propose a research method on the damage to roof of low-rise buildings subjected to typhoons based on Monte Carlo simulation,and the changes of roof damage during the typhoon courses were investigated.Based on this method,the damage of different roofs considering the impacts of wind speed and direction were analyzed and the results were compared with the damage at the time of typhoon extreme wind speed.The results show that there is a linear relationship between the damage duration and the typhoon duration.The maximum damages are often inconsistent with the damages at the time of extreme wind speed.The method which analyzes the damage under a certain wind speed will underestimate the degree of roof damage,with an average error of about 20%.In some simulations,the error can even reach 60%.关键词
