Análise da influência da rigidez de ligação em estruturas treliçadas de madeira com chapa de dentes estampados

Abstract

Wood truss structures are often used in civil construction due to their efficiency. The industrialization of this type of structure in prefabricated model is recent. This process is possible due to a new technology developed for connecting the trusses elements, the connection by metal plate connectors. Despite being an efficient method for connection, the trusses are designed with an assumption that they are pinned or rigid. However, a MPC joint has a semi-rigid joint feature and this influences the displacements and internal forces of the structure. Therefore, this kind of joint must be considered in the structural analysis. The focus of this work is illustrates the influence of the type of connection in a truss by numerical simulations, varying the models of how the elements are connected, and the experimental analysis of a truss linked by MPC in real scale, comparing the results at the end.
