“…These studies mostly consider the effect of semi-rigid joints on the structural performance of frames. In recent years, Talebi et al [17], Concepción Dí az et al [20], Zahmatkesh et al [21] suggested a new method for the optimum design of semi-rigid steel connections using kriging and Latin hypercube approaches. This methodology was applied to two examples involving bolted EEP connections.…”

An Overview of the Connection Classification Index

This research evaluated the beam-to-column connection classification index recommended by Eurocode 3 Part 1.8 and ANSI/AISC 360-10 specifications. A test programme was considered to examine the moment-rotation (M-θ) curve of semi-and fully rigid connections with variable parameters. The maximum moment capacity and initial elastic stiffness of the connections were the main parameters resulting from the M-θ curve. The performance of beams with semi-rigid connections was also evaluated through a classical method. The results clearly showed that the Eurocode 3 specification provides a more reliable classification index for the investigated connections. By evaluating the data of this research, a new classification system based on the rigidity, ultimate strength level, and ductility requirements was proposed. The results of this research provide an important contribution to the existing literature as the actual responses of beam-to-column connections are semi-rigid, and therefore such behaviour should be included in the analysis and design method.

“…From the literature review, it can be seen that the bolted slant end-plate connections could be one of the most economically generated methods [ 6 ]. These connections can sustain against the large axial load subjected to temperature increase.…”

“…These connections can sustain against the large axial load subjected to temperature increase. The resulted equations of analytical model [ 6 ] show that, after an increase in temperature in the beams with conventional (vertical) connections, a huge extra axial force will be induced into the beam. This thermal axial force can decrease the capability of member to carry external symmetric-gravity loads.…”

Research on the steel structures with confining of axial expansion in fixed beams has been quite intensive in the past decade. It is well established that the thermal behaviour has a key influence on steel structural behaviours. This paper describes mechanical behaviour of beams with bolted slant end-plate connection with nonsymmetric gravity load, subjected to temperature increase. Furthermore, the performance of slant connections of beams in steel moment frame structures in the elastic field is investigated. The proposed model proved that this flexible connection system could successfully decrease the extra thermal induced axial force by both of the friction force dissipation among two faces of slant connection and a small upward movement on the slant plane. The applicability of primary assumption is illustrated. The results from the proposed model are examined within various slant angles, thermal and friction factors. It can be concluded that higher thermal conditions are tolerable when slanting connection is used.

This paper presents a detailed comparison of two types of slanted end-plate connections, under symmetric and non-symmetric gravity loads, in terms of friction factors and angles of slanted end-plate connections. This study contributes to better understanding of roll of slanted end-plate connections under non-symmetric gravity loads on the value of the induced initial axial force due to elevated temperature in steel beams, and a comparison of the effect of symmetric gravity loads on the behaviour of such connections, before and after elevated temperature. The results imply that, before any thermal effects, a non-symmetric gravity load can be more critical than a symmetric load; the average ratio of axial force of a non-symmetric load to a symmetric load was found to be 1·49–1·57. This value was determined to be 1·64–1·90 when friction bolts instead of normal bolts were used. On the other hand, when a steel beam is subjected to a temperature increase, the amount of reaction and initial axial forces in the steel beam are not related to the type of loading. This can be considered an advantage of the slanted end-plate connection compared with a conventional vertical end-plate connection, and it could be developed in structures exposed to longitudinal movement due to expansion. The optimum angle of the slanted end-plate connection in both cases ranged from 17° to 60°.
