Conforto humano em edifícios altos devido ao efeito do vento

Abstract

This work aims to sort informations about vibration levels for human confort in high building produced by lateral action of the wind. Based on the researched bibliography three methods for maximum recommended limits have been classified herein. Among of methods for obtaining the wind load, in the present analysis of a real structure, Davenport method, the two methods presented by the brasilian wind code (NB-6123), i.e., the simplified method and the discret method, and a consisted dynamic method have been used. The vibration levels have been obtained using those methods for posterior analysis of human confort. This analysis has shown a significant difference of the Davenport method in comparison with the others methods. The choice of a method for obtaining the wind load has shown little influence on the check of human comfort. For the presented example, all the results have located the structure in the same confort condition. The comparison of the referred limits is not straightforward, since those informations are referred to distinct perception levels. Nevertheless, the presented classification facilitates the analysis of human confort in design.
