建筑物表面脉动压力测量与分析

建筑物表面的脉动压力分布及其特性，是引起结构物动态响应的重要原因之一。本文以建于台北县的某办公大楼为模拟对象，系统地研究了脉动压力测量中传压管路对测试系统频响特性的影响，通过采用串接毛细管抑制共振峰的方法很好地改善了系统的频响特性，并给出屯其研究结果。

Pressure Fluctuations on the Surface of Tall Buildings

Recently tall buildings tend to be higher and lighter along with the advance of design and construction techniques. Therefore, research into the wind load characteristics of tall building will directly affect the reasonableness, economy and safety of structure design.This paper presents the test results of the fluctuating pressure distributions on the model of a tall building group consisting of two structures erected in Taibei on the scale of 1:300. Methods of correction of distortion effects caused by acoustic resonances and damping of tubing systems, the interaction effects in neighbouring tall buildings and methods of data processing have been investigated.
