北京西站主站房建筑风荷载模拟实验研究

Simulation Test of Wind Load Characteristics of the Main Terminal Building of Beijing West Railway Station

本文对北京西站主站房建筑的风荷载特性进行了模拟实验研究。实验中模拟了两种不同大气边界层速度型（梯度风速）分布，测量了各个主要建筑物面的风载体型系数大小、分布及其随风向等因素变化的规律，详细讨论了建筑物上的某些物面形状设计对风载体型系数的影响。

This paper presents the simulation test of the wind load characteristics of the main terminal building of Beijing West Railway Station. In the test, velocity gradient distributions of two different atmospheric boundary layers were simulated. Structural shape factors of wind load of various main buildings, their distributions and changes with different conditions of wind directions were tested and measured. Besides, effects of building shape on the structural shape factors of wind load are discussed as well.
