Reliability analysis of a timber truss system subjected to decay
Brites, RD; Neves, LC; Sapotiti Machado, J; Lourenço, PB; Sousa, HSAssessing the safety of existing timber structures is of paramount importance for taking reliable decisions on repair actions and their extent. The results obtained through semi-probabilistic methods are unrealistic, as the partial safety factors present in codes are calibrated considering the uncertainty present in new structures. In order to overcome these limitations, and also to include the effects of decay...
In situ measured cross section geometry of old timber structures and its influe...
Lourenço, PB; Sousa, HS; Brites, RD; Neves, LCOld timber structures may show significant variation in the cross section geometry along the same element, as a result of both construction methods and deterioration. As consequence, the definition of the geometric parameters in situ may be both time consuming and costly. This work presents the results of inspections carried out in different timber structures. Based on the obtained results, different simplified...
