Abstract

The analysis of asymmetric T-stub components by the position of bolts respect to the web, has been carried out using numerical and experimental approaches. The main objective of this analysis is to evaluate the influence of such asymmetry on the stiffness and strength. A matrix frame model with beam-column elements and rigid connections has been developed as well as with solid elements. Results obtained with these numerical models have been compared with those obtained from experimental tests carried out, for both symmetrical and asymmetrical components, obtaining errors below 10% for stiffness and lower than 20% for the final strength. It was found, as expected, that the asymmetry leads to a redistribution of the load on the bolts, causing premature failure of the assembly. Therefore the numerical analysis performed is capable of quantifying such redistribution.
