چکیده انگلیسی
The work in this paper presents the results of a series of finite-element simulations aiming at the prediction of initial stiffness and ultimate moment for T-stub connections. The developed finite element models using ABAQUS software are verified by comparison with previous experimental tests by others. Several parameters, such as the material properties, flange thickness, web thickness, flange length, and web height of T-stub, gage distance, height of column, and depth of beam are considered in the analysis. An improved model for the initial stiffness is proposed, and it agrees well with the various test data. The types of collapse mechanisms for T-stub connections are also established. The model of ultimate moment capacity is proposed, and good agreement between the proposed model and the various test data is shown.
