| Abstract | |
This work presents a study of the precast panels contribution in the main frame stiffness, subjected to lateral loads. At first, currents criteria of panels design are analyzed, without considering the interaction with the main frame. After that, three examples are calculated using numerical simulation to evaluate this effect. These examples include the following situations: a single panel, an one-story frame and a multi-story frame. The parameters are: the frame displacements, the connections efforts and the panels tensions. The results show the magnitude of the panels contribution. In fact, to the one-story frame, it was possible to pass from a flexible structure where the second-order effects must be taken into account to an other one where this effects could be neglected. For the multi-story frame analysis, the panels contribution produced an effective material economy of about 20% (and consequent cost reduction). Basing on these results, one can conclude that the infill panels can be included in the design strategy with economy for the structural system. (AU) | |
