Abstract

The invention discloses a wind load and wind-induced effect evaluation method and system for a complex lattice type framework structure, and the method comprises the steps: obtaining a plurality of typical segments from the complex lattice type framework structure, and building a typical segment model for each typical segment; the method comprises the following steps: firstly, carrying out a multi-balance synchronous test wind tunnel test on a plurality of typical segment models based on different transverse, vertical and front-back distances to obtain a base shear force of each typical segment model, obtaining wind load information according to the base shear force, and calculating a load spectrum of a multi-mass-point freedom degree model according to the wind load information of each typical segment model; the method comprises the following steps: acquiring a load spectrum of an actual structure, converting the load spectrum into a load spectrum of the actual structure, performing wind-induced effect evaluation on the complex lattice type framework structure to obtain a wind vibration coefficient, evaluating the wind load and the wind-induced effect of the complex lattice type framework structure from a local part to an overall part and from a model to the actual structure, and considering the structural characteristics of the complex lattice type framework structure. Therefore, effective wind load and wind-induced effect evaluation of the complex lattice type framework structure is realized.
