The current paper presents the outcomes of an extensive pre-test numerical investigation program carried out with the aim to validate the design procedure for bolted beamto- column connections with haunches. In the first part of the paper, a description is made with regard to the analytical procedure that was used for the design of full strength and rigid joints. The results from the pre-test numerical simulations are further presented for each beam-to-column joint assembly, in terms of overall response (moment-rotation curve, failure mechanism), as well as local response, particularly the behavior of joint components (stress distribution, plastic strain, force level in the preloaded bolts). Finite element simulations highlighted that plastic deformations occurred in the beam close to the end of the haunch. In addition, minor plastic deformations were observed in the bolts close to the beam flange in tension, and therefore also higher force levels compared to the computed design capacity. As a result, the design procedure was adjusted with the aim of keeping the non-dissipative components of the joints in the elastic range. Additional information is presented with regard to the position of the plastic hinge, the effect of preloaded bolts, the distribution of forces in bolt rows and the change of the lever arm due to the presence of the haunch in compression zone. The main conclusions of the study are finally presented.
