Abstract

The invention provides a method for researching dynamic response under a structural wind load by combining numerical simulation with physical test, belongs to the field of structural disaster prevention, and particularly relates to the field of structural wind resistance test research. According to the test method of the invention, an actual engineering structure is divided into a test substructure (1) and a calculation substructure (2), the test substructure (1) is loaded through a novel wind excitation device (4), the calculation substructure (2) performs computer numerical simulation through structure analysis software, and the test substructure (1) and the calculation substructure (2) interact through a data exchange system (3), so that response of the whole structure under external wind excitation is obtained. According to the method, the problem that the response of a complex engineering structure under a wind load is difficult to accurately simulate due to size limitation in a traditional wind tunnel test is solved; and particularly, the defect of high difficulty in a wind loss test and the like are overcome, the size limitation of a structural model is broken through, the test cost is reduced, the extreme wind load simulation effect is more ideal, and the requirements of engineering technologies and researchers can be met.

Description

technical field [0001] The invention proposes a test method combining numerical simulation and physical test for studying the dynamic response of structures under wind load, which belongs to the field of structural disaster prevention, especially the field of structural wind resistance test research. Background technique [0002] Wind disaster is one of the main types of natural disasters. In recent years, due to global warming, wind disasters have become more serious, causing global economic losses of tens of billions or even hundreds of billions of dollars every year. The study of wind resistance of civil engineering structures is a very important discipline in the field of disaster prevention and mitigation. Traditional structural wind resistance test studies mostly use wind tunnel tests to simulate the effect of natural wind on the surface of structures. However, the scale of the existing wind tunnel laboratory is often difficult to meet the requirements of the full-sc...
