| The objectives of this paper are to study the effect of different parameters for steel bolted angle connection on moment-rotation behavior under monotonic loading. ABAQUS software is used to develop analytical models based on the previous experimental studies and their accuracy is examined. Using verified analytical models, a parametric study is then carried out to study the moment-rotation behavior with variations in: beam size, top angle thickness, and bolt gauge distance. From the results, the bi-linear moment rotation diagram for the connection is determined and the following results were obtained with respect to the initial stiffness, post-limit stiffness, plastic flexural resistance moment, plastic rotation, ultimate moment, and ultimate rotation. Finally, the effect of each parameter on moment-rotation behavior of the bolted angle steel connection is discussed in detail, and a proposed formula between each parameter and results is estimated. | ||
