Multi-channel system

The parallel tube-manifold system is applied to augment the number of simultaneous measuring points to ensure that the non-steady wind pressures on a large-span roof can be obtained simultaneously from the rigid model wind tunnel test.

该方法采用多通道测压系统扩大同步测压点的数目,更全面地获得屋盖表面风压的时空特性,为准确计算结构风致响应奠定了基础。
