The dynamic mechanical properties of concrete materials are important parameters for evaluating the safety performance of concrete structures under dynamic loads. Fiber cement-based materials have been widely used in the construction projects due to their strength, toughening, and cracking resistance. In this study, we conducted experimental and theoretical studies on dynamic compression and tensile mechanical properties of different proportions of new-type fiber concrete. A Split-Hopkinson pressure bar equipment was used to determine the concrete behavior at different strain rates. The effects of strain rate and fiber content on the strength of the specimen, dynamic increase factor, and ultimate strain were analyzed. Based on the macrodamage factor, the traditional nonlinear viscoelastic constitutive model was simplified and improved. The four-parameter constitutive model was obtained, and the influence of these parameters on the performance of fiber concrete was analyzed. The experimental results were compared with those predicted from the available equations, and results were in accordance. Finally, an analytical equation for predicting the dynamic compression and tensile properties of these new-type fibers was proposed.

“…Most research on properties of concrete subjected to high strain rate loadings has focused on compressive strength. It is generally accepted that there is a strength increase with the increase in strain rate [7][8][9]. Mindess [10] found that an increase in the strain rate leads the elastic modulus to increase.…”

“…reduction coefficient of bearing capacity (α) is found to be 0.98, which indicates that the bearing capacity of the grouted sleeve splice is slightly lower than the tensile capacity of the connecting steel bar itself. This can be attributed to the failure mode and eccentricity of the embedded bars [41,42], as showed in Fig. 22.…”

This paper presents an experimental and analytical study on mechanical behaviour of two kinds of new low-cost grouted sleeves processed by seamless steel pipe, i.e., grouted sleeve with wedge and grouted sleeve with wedge and thread, under uniaxial tension. In total, twenty-two rebar splice specimens with various embedded lengths, spliced bar diameters and wedge lengths are prepared and tested. The test results indicate that the performance of both grouted splices meets the requirements of ACI318 and JGJ107. The required embedded length of rebar in the splice is found to be around 6-6.4 times the spliced bar diameter due to confinement effect. The tensile capacity of the splice increases with increasing diameter of the anchorage segment of the spliced bar, and length and slope of the wedge at both ends of the sleeve. Because of the good performance of wedges threads do not significantly improve the tensile capacity of the sleeve but improve the bond strength and bearing capacity in non-wedge segment of the sleeve. The tensile capacity of the specimen is slightly lower than that of steel bar and the reduction coefficient of bearing capacity is estimated. An analytical model is proposed to predict the tensile capacity of grouted sleeves considering the effects of confinement and reduction of tensile capacity of the splices, the predictions of which are in good agreement with experimental data.

This paper presents an experimental study of a new grouted splice connection for wall panels, called Welded Bar Sleeve (WBS). The connections were made from steel pipes and tested with incremental tensile, shear and flexural loads until failure. The aim is to determine the behaviour of the connection under the three load cases. For this, the connections are evaluated in terms of the load-displacement responses, ultimate capacities, ductility responses and some feasibility assessment criteria. WBS was found to provide sufficient strength at the bar embedded length of 8, 8 and 11 times the bar diameter under tensile, shear and flexural loads, respectively. It is effective under tension, but could only service up to 1/3 of its ultimate shear capacity. Flexural load is the most critical load case for the connection. For this, further enhancements are required when subjected to shear and flexural loads.
