“…This, coupled with non-conforming elements, which are typically used to model bolt head and shank, has introduced complexities in the connection mechanism model. This complexity was observed by Kukreti and Murray [20], Kukreti and Prasad [18], and Kukreti and Biswas [19]. In some cases such as those reported by Choi and Chung [10], non-conforming elements were employed for exact and complicated bolt assemblage modeling, which may retard or damage the monotonic convergence unless an accurate patch test is conducted.…”

“…Ghassemieh and Kukreti [12], and Kukreti and Biswas [19] developed a cyclic plasticity-based 3D FEM algorithm to predict hysteretic behavior of end-plate connections under low frequency cyclic loads. This incremental formulation included a unique algorithm for predicting possible crack initiation in the welded regions.…”

“…So far, there have been extensive studies on the seismic behavior of steel beam-tocolumn extended end-plate connections. Some representative experimental [3][4][5][6][7] and numerical [8][9][10][11][12][13] work of high quality on this type of connection can be found. Nowadays, high-strength structural steels with a nominal yield strength of at least 460 MPa have been developed and are increasingly recognized as structural materials to arrive at more economical or reliable solutions in structural design [14,15].…”

In order to examine the seismic behavior of high-strength steel extended end-plate connections, a three-dimensional efficient finite-element model in Abaqus was established subjected to cyclic loading at the beam end. Geometrical dimensions, boundary conditions, element types, contact properties between the bolts, end-plate and column flange, and material cyclic constitutive models were described in detail. Geometry and material nonlinearity were adequately considered. In particular, a cyclic plasticity model for high-strength steels was employed that was easily calibrated based on the tension coupon test, so as to describe the complicated cyclic hardening and softening response. The simulated results of the finite-element model were compared to the test ones in terms of both deformation modes and hysteresis loops. The results showed that the bending deformation of the end-plate and column flange was accurately captured, and the gap phenomena among the bolt nuts, the end-plate, and column flange was described in a satisfactory manner as well. The hysteresis loops from the simulation agreed well with the test results, reproducing the pinched shape due to the end-plate gap evolution under cyclic loading as well as the quite plump shape with stable energy dissipation when the panel zone dominated the cyclic response. Therefore, the accuracy of the finite-element model was verified and it provided a strong benchmark tool for investigating the cyclic or seismic performance of this kind of connection. The connection failure including the bolt fracture and cracking in the end-plate needs further numerical study by calibrating accurate material failure models for high-strength steels and bolts.

“…As far as numerical modeling is concerned, Krishnamurthy and Graddy (1976) established the first report of finite element analysis (FEA) for end-plate connection (Shi et al, 2008). Kukreti and Biswas (1997) developed a computer code and used it to analyze the moment-rotation behavior of three eight-bolt end-plate connections subjected to seismic loading. An overprediction of the moment at any rotation level of 5%-12% for the connection was observed when comparing moment-rotation hysteresis loops using the FEAs.…”

The flexural behavior of partially welded flush end-plate connections incorporating built-up hybrid beams and columns is analytically and numerically investigated. An experimentally obeying three-dimensional finite element model is first constructed. To circumvent the laborious effort of three-dimensional simulation and experimental work, a new experimentally and numerically complying equation approach is introduced for the construction of a continuous moment-rotation (M-u) description. For the proposed equation, two essential terms are required: the rotational stiffness, S j,ini , obtained by employing the component method and the maximum moment, M max , produced using the proposed linearly distributed multi-parameter fitting technique. To demonstrate the applicability of the proposed equation, a variation in the geometric configuration of connections within the practical range is considered. Excellent agreement is noted when comparing all M-u relationships produced by the proposed equation to those by the finite element method and experiments. In addition, the stress distribution and main deformation modes are numerically obtained, where the ranking of stress criticality is offered for all structural parts. The depth, width, flange, and web thicknesses, as well as the yield stress of the beam, have a major influence on M max , as predicted by the proposed equation. Also, bolts have been identified as the most critically stressed component.
