建筑结构风荷载及其动态响应研究

The investigation of wind loads and dynamic responses on tall buildings and structures

在过去的几十年里 ,虽然人们对高层建筑风效应的问题已有了一定的了解 ,但对大气流场与结构物各种风致响应的关系机理的认识还有待于进一步提高。确保结构系统在强风期间的安全性与舒适性是一个重要的设计目标。笔者给出了大气边界层模拟要求 ,并介绍了一种研究建筑物的表面脉动压力和高层建筑动态响应的方法。

Although the knowledge of wind effects on tall buildings and structures has significantly improved over the last decades, an understanding of the mechanism that atmospheric flow field to various wind induced effects on structures has not been development sufficiently for formulation of functional expressions. The assurance of safety and serviceability of tall buildings and structures under strong winds is an important design objective. In this paper, the simulation technique about atmospheric boundary layer, the experimental measuring technique of fluctuating pressure and dynamic responses on tall buildings and structures has been introduced.
