“…6 were applied to the displacement control at the end crosssection of the column with a loading rate of 6.25 mm/min which is 15 times greater than the loading rate used in the test. It can be observed that if the smooth step was used, the predicted response was very smooth and close to the test result [16]. Meanwhile, the response generated by the linear step exhibited some vibrations due to inertial dynamic effects, especially in the initial range when the behaviour of the connection is linear elastic.…”

“…The compressive and tensile strengths of concrete are 17.5 MPa and 1.7 MPa, respectively. The specimen was put upside down, and a loading rate of 0.4mm/min in the linear elastic range was applied to the CFST column and then increased to 1.0 mm/min in the nonlinear range towards the failure [16].…”

“…Experimental studies have been carried out to predict the moment-rotation behaviour of bolted endplate beam-to-CFST column joints with steel beams [4][5][6][7][8][9][10][11][12][13][14][15] and composite beams [16][17][18][19][20][21][22][23][24][25]. However, as summarised in Thai and Uy [26], the number of tests on the considered joints is still limited due to expensive cost and time consuming.…”

This paper explores the use of an explicit solver available in ABAQUS/Explicit to simulate the behaviour of blind bolted endplate connections between composite beams and concrete-filled steel tubular (CFST) columns. Main aspects of the explicit analysis such as solution technique, blind bolt modelling, choice of element type and contact modelling are discussed and illustrated through the simulation of a large-scale test on the considered joint. The mass scaling option and smooth step amplitude are very effective tools to speed up the explicit simulation. Shell elements can be used in modelling the I-beam due to their computational efficiency and accuracy in capturing local buckling effects. With a proper control of the loading rate, the explicit analysis can provide accurate and efficient predictions of the quasi-static behaviour of the bolted endplate composite connections.

The behaviour of anchored extended blind bolts in concrete‐filled tubes

et al. 2022

View full text Add to dashboard Cite

Extended Hollo-Bolts (EHBs) are blind bolts that have an extended bolt shank ending in an anchor nut. When used with concrete-filled tubes, the extension and the anchor in the concrete serve to enhance significantly the performance of both connection components: bolts in tension and tube face in bending. The enhancements are a result of confining the concrete, preventing local buckling of the steel tube and allowing the blind bolt to achieve a tensile strength equal to that of standard bolt+nut fasteners. Overall, the use of the EHB results in a moment-resisting bolted connection to hollow sections which can achieve rigid behaviour under certain configurations. This paper summarizes research work done to date on such connections at the University of Nottingham. This includes experimental, numerical and analytical modelling. The aim of the work is to provide a fundamental understanding of the behaviour of anchored blind bolt connections to concretefilled columns, leading to the specification of appropriate design rules that allow the use of such bolted moment-resisting connections in practice. The work has proposed analytical models for: connection stiffness, column face-bending strength considering both single and group behaviour of bolt rows, anchored bolts in tension and anchored bolts under combined tension and shear.
