Abstract

Finite element models are suggested for the analysis of a special type of semi-rigid connections of frame structures, known as saddle-like connections. The performance of these models is verified through the available experimental results. Non-linear finite element analysis is performed for a total number of 138 connections, and M-phi diagrams are obtained. Each diagram is represented by a multi-linear relationship through seven points. A neural network is trained for the prediction of M-phi diagrams for saddle-like connections. The results obtained by the trained backpropagation neural network are found to be quite satisfactory compared to those of the finite element analysis.
