This paper proposes a novel method to estimate the lateral displacement of high-rise structures under wind loads. The coefficient β(x) is firstly derived, reflecting the relation between the structural lateral dynamic displacement and the inclination angle at the height x of a structure. If the angle is small, it is the ratio between the structural fundamental mode shape and its first-order derivative without influence of external loads. Several dynamic experiments of structures are performed based on a laser remote sensing vibrometer and an inclinometer, which shows that the fundamental mode is dominated in the structural displacement response under different types of excitations. Once the coefficient β(x) is curve-fitted by measuring both the structural lateral dynamic displacement and the inclination angle synchronously, the real-time structural lateral displacement under operational conditions is estimated by multiplying the coefficient β(x) with the inclination angle. The advantage of the proposed method is that the coefficient β(x) can be identified by lateral dynamic displacement measured in high resolution by the remote sensing vibrometer, which is useful to reconstruct the displacement accurately by the inclination angle under operational conditions.

基于遥感测振仪和倾角仪融合的高层建筑在风荷载下的侧向动态位移估计

本文提出了一种新的方法来估算风荷载作用下高层建筑的侧向位移。首先导出系数β（x），以反映结构横向动态位移与结构高度x处的倾斜角之间的关系。如果角度较小，则它是结构基本模式形状与其一阶导数之间的比率，而不受外部载荷的影响。基于激光遥感测振仪和倾角仪进行了几次结构动力学实验，结果表明，在不同类型的激励下，基本模式在结构位移响应中占主导地位。通过同时测量结构横向动态位移和倾斜角，对系数β（x）进行曲线拟合，通过将系数β（x）乘以倾角来估算运行条件下的实时结构横向位移。所提出的方法的优点在于，可以通过遥感振动计在高分辨率下测得的横向动态位移来识别系数β（x），这对于在工作条件下通过倾角精确地重建位移是有用的。
