Numerical Modelling of Semi-rigid Connection with High Strength Steel

Numerical Modelling of Semi-rigid Connection with High Strength Steel This work offers a three-dimensional finite element model of a flush end plate connection and the full interaction between plate columns is simulated by contact element using ANSYS 10.0 software aid. The analysis results of the moment- rotation relationship and behaviour characteristic of the connection with high strength steel are compared and discussed. The moment capacity prediction of flush end plate connections based on EC3 has been shown to be reasonable compared with finite element (FE) modeling. The proposed FE connection model is capable of predicting the ultimate load capacity and the plastic strain pattern with good accuracy. The model presented gives excellent results for increasing the connection capacity significantly due to employed higher strength steel section. The four parameter model is proposed to predict M–θ model through curve fitting for FEP connection with high strength end-plate. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Study of Civil Engineering and Architecture Science and Engineering Publishing Company

Abstract

This work offers a three-dimensional finite element model of a flush end plate connection and the full interaction between plate columns is simulated by contact element using ANSYS 10.0 software aid. The analysis results of the moment- rotation relationship and behaviour characteristic of the connection with high strength steel are compared and discussed. The moment capacity prediction of flush end plate connections based on EC3 has been shown to be reasonable compared with finite element (FE) modeling. The proposed FE connection model is capable of predicting the ultimate load capacity and the plastic strain pattern with good accuracy. The model presented gives excellent results for increasing the connection capacity significantly due to employed higher strength steel section. The four parameter model is proposed to predict M–θ model through curve fitting for FEP connection with high strength end-plate.
