Abstract
Top and seat angle connection with double web angles (TSADWA) is generally considered as semi-rigid and partial strength category and it is widely used in steel framed buildings and commonly used for low-rise buildings. There are some codes such as Eurocode, for the prediction of stiffness and strength of this type of connection yet there are no rules for characterization of the ductility of this joint. By using modern computing techniques, finite element analysis has become a practical tool for engineering analysis and design. Development of proposed equations require a wide range of experimental studies which is costly, time consuming and uneconomical. So, this problem can be simplified with using ABAQUS software, which is finite element model analysis program. This study presents and discusses results of parametric analysis of bolted angles connections under monotonic loading using finite element modeling tools. The finite element model took into account both material and geometrical nonlinearities. The analysis was calibrated to a published experimental results and satisfactory agreements are obtained. In this thesis, the studied parameters are beam size, top and bottom angle thickness, bolt gauge distance, and top bolts diameter. The results from the parametric study are discussed in details, and simple equations are proposed for pre-estimating the Bilinear response behavior of the steel connection with respect to the initial stiffness, post-limit stiffness, plastic flexural resistance moment, plastic rotation, ultimate moment, and rotation related to ultimate moment, and the effect of semi-rigid connections behavior on structural response have been studied.
