Abstract


Besides their function of transmitting vertical loads, the floors transmit horizontal seismic forces, developed during an earthquake, from the masses concentrated at each level to the bracing elements. They also help maintain a connection between the various elements of the structure. Given the characteristics of traditional wooden floors and those of the structures in which they are incorporated, special provisions are necessary to the floors in order to be able to play this dual role. In many cases, the design calculations of wooden floors assume that the support nodes behave as perfect hinge or the joints are perfectly rigid. In practice, most used connections have a semi rigid behavior. For such assemblages, relative deformations appear between the connected structure elements. The present paper aims to provide recommendations and design features for optimum performance of traditional wooden floors with a single slope, when subjected to earthquake forces. In particular, this approach takes into account the orthotropic and possibly plastic behavior of wood and the flexional behavior of the connections between walls and floors in the overall analysis of the structure.
