摘要
回顾了中国建筑科学研究院近年来在风工程领域取得的重要研究进展。风荷载研究方面,在提出风振计算广义坐标合成法基础上,建立了基于响应时程的结构等效静风荷载计算体系,开展了复杂高层建筑风致振动的系统研究,探明了高层建筑弯扭耦合风振响应的基本规律,提出了高层建筑横风向响应的反应谱方法。风环境研究方面,提出了平衡边界层新的理论解释和数学模型,以及植被和绿化带数值模拟的附加源/汇数学模型。提出了考虑地貌修正的气象资料修正方法,建立了基于日最大风速记录的风环境评估体系,开展了列车风和烟囱效应等特殊风环境的研究。雪荷载研究方面,开展了雪荷载风洞试验和数值模拟技术的研究,提炼了雪荷载风洞试验模拟的核心相似参数,阐明了风致积雪飘移的流动机理,开发了CFD数值模拟的相关程序。团队研究成果在重大工程中得以广泛应用,部分成果被纳入国家和行业标准规范。
The important progress made by the China Academy of Building Research in wind engineering in recent years is reviewed. In terms of wind load research,by the means of the generalized coordinate synthesis method for wind-induced vibration,a structural equivalent static wind load analysis system based on response time history is established. A systematic study of the wind-induced vibration of complex high-rise buildings is carried out. The characteristics of bending and torsional coupled vibrations of tall buildings under the wind action are presented,and the response spectrum method for the cross-wind vibration of a high-rise building is proposed. In the field of wind environment research,a new theoretical interpretation and mathematical model of the equilibrium boundary layer are proposed,and a mathematical model of additional source/sink for numerical simulation of vegetation and green belts is suggested. A meteorological data correction method accounting for terrain variations is put forward,and a wind environment evaluation system based on daily maximum wind speed records is established. Special wind environments such as train-induced wind and chimney effect are studied. In the study of snow load,the wind tunnel test and numerical simulation technology are carried out,the essential similar parameters of wind tunnel test are suggested,the flow mechanism of wind induced snow drift is clarified,and the related program of CFD numerical simulation is developed. These results have been widely applied in major projects,and some of them have been incorporated into national and industrial standards.
