Determination of the dynamical component of wind loads on multi-storey building structures using dynamic analysis and TCVN 2737:2020

Abstract

The objective of this paper is to study quantitatively the dynamical component of wind loads acting on multi-storey building structures by dynamic analysis and to compare with the calculation from TCVN 2737:2020. The wind load are assumed to be time-varying with different impulsive loads and different durations of action in the dynamic analysis. The structures is a model of a 30-storey building which is discretized by finite element method in static and dynamic analysis by SAP2000 software. The results show that the dynamical component sensitively depends on the ratio of the duration of the impulsive wind and the natural period of the structure, and the magnitude of dynamical component is also approximately close to the determination method according to TCVN 2737:2020.
