RESUMO:

The semi-rigid connections play an essential role on the behavior of steel structures, because influence the internal efforts distributions and structural stability. Conventional analyses in structures are made admitting the behavior of the connections as ideally pinned or perfectly restrained, in order to simplify the calculations and to reduce the necessary time for the design. However, the behavior of most connections resides between these two extremes, i.e., it is actually semi-rigid. The behavior of steel structures can be obtained by numerical analysis, including the effects of semi-rigid connections, as well as the geometric and material non-linearities. The objective of this work is to present a study the elastoplastic behavior of one steel plane frame with flush end plate connection considering the Advanced Analysis using the LUSAS program. Initially, analyses have been made and the flush end plate connections results were calibrated, after, this connection was inserted in the steel plane frame to validate the three dimensional non-linear FEA. The numerical analysis results were satisfactory when compared with the experimental analysis results. The moment rotation curve of the connection presents good agreement results, showing good representation of the behavior. The results obtained in the numerical analysis in the steel plane frame were consistent to. Concludes that the three dimensional numerical analysis can be un method of Advanced Analysis and your application can be extended to an others structures behavior studies, in the precision verification of the simplified method of analysis, in the experimental results comparison and to obtain the moment rotation curve of the connection.
