Research on Equivalent Static Load of High-Rise/Towering Structures Based on Wind-Induced Responses

A method of assessing equivalent static wind loads that can represent all the real ultimate states a high-rise building and towering structure has still not been fully determined in engineering. Based on random vibration theory, wind-induced response loading buildings structures are investigated using decomposition method. Firstly, structural mean response, background resonant coupled studied time frequency domains. Secondly, new gust load factor (GLF) assessment suitable for displacement, bending moment shear force at any height is proposed, typical used as an example comparison with previous research results, order to verify effectiveness this paper. The results show following: structures, percentage components total pulsation less than 2%, influence be ignored; GLF based (MGLF) (QGLF) increase significantly height, traditional methods underestimate maximum effects.
