Investigation of the effects of bolt diameter and end-plate thickness on the capacity and failure modes of end-plated beam-to-column connections

Abstract

End-plated connections are frequently preferred in beam-to-column connections due to their advantages of high quality and fast assembly. The capacity of the end-plated connections depends on many parameters including the thickness of end-plate and bolt diameter. A comprehensive numerical parametric study was conducted in order to investigate the effects of these parameters on the capacity of the end-plated connections using the finite element tool, ABAQUS. The results of the numerical study were compared with the prediction of Eurocode provision in terms of the capacity and failure mode. The results showed that Eurocode accurately captures the failure modes and predicts the capacity of the connection except for thin plates with high accuracy. However, Eurocode provision significantly underestimated the capacity of the thin-plated extended end-plated connections.

Optimization of Bolted Joints: A Literature Review

“…Changing from steel to cast iron over aluminum members caused a 7.8, 7.6, and 7.4-percent decrease in bolt stiffness [128]. According to the findings of others, the initial stiffness of the endplated connection improves along with an increase in either the bolt diameter or the end-thickness [129].…”

Assessing Effectiveness of Shape Memory Alloys on the Response of Bolted T-Stub Connections Subjected to Cyclic Loading

“…In keeping with this discovery, Asada et al [82] described a method for increasing the plasticity of welded wide flange beam to column connections by using high-yield bolts and welding complementary H-section haunches. Ozkilic [44][45][46][47] evaluated behavior of stiffened extended end-plate connections with large bolts, application of extended end-plate connections for replaceable shear links, effects of yield line mechanisms of four bolted extended end-plate connections on frame response, and impacts of bolt diameter and end-plate thickness on capacity of connection and failure modes under cyclic and monotonic loading.…”
