In the last decades, based on the substantial growth of urban populations, the demand for space for housing has grown dramatically. To meet these needs, building ever higher and more slender are designed and increasing spans has been used. New materials are created and improved to be extracted maximum performance at the lowest cost. Thus, this research work aims to study the structural behaviour and human comfort of reinforced concrete buildings. To do this, it is considered throughout the study the design of four different reinforced concrete buildings with height in the range of 30m to 70m (10 to 24 floors), subjected to the actions of usual design loadings on residential buildings in addition to wind loads. Regarding the development of the computational model, usual mesh refinement techniques are used, based on the finite element method simulations, and implemented in the ANSYS program. Initially, the structural models static (displacements and efforts) and dynamic (peak accelerations) response is obtained and compared, based on the limiting values proposed by design standards and technical recommendations. Based on the developed qualitative and quantitative analyses on the investigated structural models response, the structural performance of the analysed buildings is evaluated, on the point of view of human comfort.
