Experimental and numerical study of mechanical properties for the double-ribbed reinforced beam-column connection

Popis výsledku v původním jazyce

This paper investigates the hysteretic behavior of steel reinforced beam-column connections with or without double-ribs and optimizes the reinforced ribs of these connections under cyclic loading. The objective is to give a reasonable range of double-ribs’ size and fracture behavior of the weld at beam-column connections. Two specimens (the conventional beam-column connection and the double-ribbed reinforced beam-column connection) are designed and tested under cyclic loads. Meanwhile, the finite element models of these two kinds of connections are established. The hysteretic performance and damage evolution of the connections, such as the failure modes, hysteretic curves, skeleton curves, stiffness degradations, ductility, and energy dissipation capacities, are analyzed and verified. Moreover, fifteen numerical models with different lengths of the line (la), the width (b), and the thickness (ts) of reinforced ribs are established for parametric study. The results show that double-ribs can improve the strength and ductility of the connection. And the FE predictions agree well with the experimental results. The reasonable parameters of reinforced ribs of double-ribbed reinforced beam-column connection are proposed.
