SISTEMAS DE VEDAÇÃO EM ALVENARIA PARA EDIFÍCIOS DE ESTRUTURA METÁLICA: DETALHAMENTO COM BASE NA PREVENÇÃO DE MANIFESTAÇÕES PATOLÓGICAS

The durability performance of multi storey buildings of steel structure is closely associated to the executive project planning in order to provide systems which are exposed to external conditions. The aim of this research was to present a methodological proposal for the design of masonry veneer systems for steel structure of institutional buildings which present high performance regarding durability. In order to execute this proposal, the performance of the veneer system of three institutional buildings was evaluated through building pathologies examination. Buildings which presented variations on the type of connections between masonry and structure, the type of masonry veneer and the type of facades finishes were surveyed. Then, the designed information was confronted with the construction method applied for the masonry veneer details. The confrontation was used to identify procedures to assist the development of a masonry veneer design which aims to prevent pathologies in steel structure. Finally, a building project were developed using the proposed methodology in a practical design exercise.
