考虑空间效应的惯容-建筑结构随机风振响应分析
Stochastic wind vibration response analysis of building structures with inerters considering spatial effects
摘要
Abstract
Aiming at the problem that the traditional planar structural model is difficult to reflect the three-dimensional spatial effect of wind load,the paper systematically investigates the influence mechanism of its three-dimensional spatial effect on the wind-vibration response of a building based on the quadratic decomposition method of the power spectrum.Using D'Alembert's principle and the real mode decomposition method,the wind vibration equations of a three-dimensional building-inertial damping system are established by considering the stiffness characteristics of the inertial system,and the exact closed-form solution of the response spectral moments under the excitation of Davenport's wind speed spectrum is derived.The correctness is verified by examples,and the spatial effect of wind excitation and the key parameters of inertial system are optimized in depth.It is shown that:the windward frame conforms to the flat cross-section assumption,and the vertical response has a gradient distribution;the structural response of the 3D model is smaller than that of the 2D model;the inertia system needs to be optimized in order to achieve the best damping control on the structure.关键词
