15.16: Vibration Analysis and Human Comfort Investigation of a Steel‐Concrete Composite Building under Nondeterministic Wind Loadings
Based on a favourable economic scenario combined with a significative technological advance in science materials and also construction processes, it must be emphasized that the Brazilian cities have shown substantial growth, regarding the construction of tall and slender buildings. This architectural trend has conducted the design of these buildings to solutions composed by very flexible structural systems, resulting in slender buildings with very low natural frequencies values and therefore more susceptible to problems of excessive vibrations, undesirable crack openings and even discomfort to the occupants. This way, having in mind the slenderness levels presented more recently, these buildings need to have their structural dynamic behaviour investigated, in order to ensure the human comfort. Thus, this research work aims to investigate the dynamic structural behaviour and also evaluates the human comfort of tall buildings, when subjected to the non‐deterministic action of the wind. This way, the structural behaviour of a forty eight‐storey steel‐concrete composite building with 172.8m high subjected to the nondeterministic wind dynamic actions is investigated. The results obtained along the numerical analysis, in terms of the displacements and accelerations values, in time and frequency domain, are compared with the limits proposed by technical guides and design recommendations, aiming to evaluate the human comfort levels of the analysed building, regarding to the situations of the design practice.
