Mechanical Performance of Novel UHPFRC Grouted SHS Tube-Sleeve Connection: Experiments, Numerical Simulation and Analytical Approaches
This paper presents the axial and lateral performance of a novel ultrahigh-performance fiber-reinforced concrete (UHPFRC) grouted SHS tube-Sleeve connection for prefabricated prefinished volumetric constructions (PPVC). The experimental study tested 18 full-scale specimens with varying shear key spacings, inner tube lengths, inner tube heights, and volume proportions of steel fiber in UHPFRC. The results showed that the connection have adequate resistance and ductility to resist tension and bending moment. The failure modes in tension mainly include the shear failure of the UHPFRC and the fracture of the inner tube, while the failure modes in bending mainly include the fracture of the inner tube and the slip of the grout. To further understand the load transfer mechanism of the connection, the advanced finite-element (FE) models were built to simulate the axial and lateral load–displacement behavior, strain and crack development of the grout. Thereafter, new design formulas are developed and evaluated to predict the axial and lateral resistance of the grouted connections. Validation against the test results showed that the new formulas can provide reasonably effective and accurate predictions of the axial-load and lateral-load resistance of the novel grouted connection.
