    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 momentrotation 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.

    ABSTRACT: This study investigates the behavior of Partially Restrained (PR) connections with high strength steel through the use of Finite Element (FE) modeling. The connection model is such that double web angles are represented by radiused corner section shell elements. The full interaction between the angle and the beam and/or column is simulated by the contact element.The analysis of the moment- rotation relationship and behavior characteristics of the connection with high strength steel are compared and discussed. It is established that the contact elements and strength enhancements of the corner regions employed in this model are important parameters for accurate predictions of Double Web Angle (DWA) connection behavior with cold-formed high strength steel. The proposed connection FE model is capable making highly accurate predictions about the ultimate load capacity and the plastic strain pattern. The model presented provides excellent results for significantly increasing the connection capacity as a result of employing a higher strength steel section. A power model expression was proposed to predict the ultimate moment and initial stiffness of the high strength DWA connection. A reasonable prediction was obtained for high strength PR connection.

    ABSTRACT: This paper investigates the behavior prediction of partially restrained (PR) connection with high strength steel by three-dimensional nonlinear finite-element (FE) analyses. The connection model is such that angle cleats are represented by radiuses corner section shell elements. The full interaction between angle and beam and/or column is simulated by contact element. The analysis results of the moment- rotation relationship and behaviour characteristic of the connection with high strength steel are compared and discussed. It is found that contact element and strength enhancement of the corner regions employed to the model are very important parameters for accurate prediction of PR connection behaviour with cold-formed high strength steel. The moment capacity prediction of top and seat angle connections based on EC3 has been shown to be reasonable compared with FE modeling. The proposed connection FE 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.

    ABSTRACT: The paper discusses the frame analysis using 3D finite element models to investigate the influence of partially restrained (PR) connections with high strength steel on steel building structure frameworks. Rigorous application of finite element computing package ANSYS 10.0 has been used to analyze the structural behaviour of the frames. The boundary restraints are represented as a combination of linear and rotational springs, where the spring stiffnesses are derived based on the assumption of semi-rigid beam-to-column connections. The strain softening is considered to analyse the beams during deformation. The proposed models are compared using a two-dimensional (2D) frame analysis. It has been demonstrated that simplified portal frame analysis with non linear spring element give significant role to predict the behaviour of PR connection due to strain softening effect up to complete failure. From these models it will be possible to establish new design methods for frame design utilising the strength and stiffness of PR connections with high strength steel utilising beam strain softening. Keywords: partially restrained connection, high strength steel, frame model, spring stiffness, strain softening, non-linear, finite element

    ABSTRACT: This paper described an investigation on the effect of openings in the flange of composite beam to the composite connection performance. The current study is based on nonlinear three dimensional (3D) finite element models. A composite joint with flush end plate connection has been used for this study. Parametric studies of openings location and size have been performed to investigate the effect to the moment rotation and structural behavior of the composite connection. The model has been validated using composite beam and composite connection experimental result for accuracy and behaviour trend before the comparison were made for influence of openings in composite connection. It has been found that the openings have potential to greatly affect the moment capacity of composite connection.

    ABSTRACT: An approach for simplified three dimensional (3D) finite element analysis of bolted steel beam-column connection behaviour has been developed by rigorous application of finite element computing package ANSYS. Non linear 3D continuum shell and solid elements are used for all parts of the connection to investigate the structural performance of partially-restrained connections. A method for applying shell and contact element in the connections is introduced and verified. The analysis results of the moment- rotation relationship and behaviour characteristic of the connection are compared and discussed. It is found that contact element employed to the model is very important parameter for accurate prediction of bolted connection behaviour with both mild carbon steel and high strength steel. A proposed simplified model using shell element is reliable to predict the behaviour of bolted beam-column connection by providing a more efficient analysis.
