摘要:

Fabricated friction dissipation re-centering brace with zero initial cable force (FZFRB) is proposed. It has simple structure and the functions of energy dissipation, re-centering, avoiding the loss of prestress. Two specimens were designed and the pseudo-static tests were made. The numerical simulations of the tests were also carried out. The results showed that, the structure that two groups of galvanized steel wire ropes with zero initial cable force alternating stress and dowel bar leading brass-slots steel plate of friction energy dissipation to consume energy is feasible. There is no stiffness degradation in the loading process, and the brace has full hysteretic curve, stability energy dissipation law. Consistence is found between the numerical simulation results and experiment hysteresis curves. When the re-centering process stops, relaxing high strength strain bolts of brass-slots steel friction plates dissipation can let the brace back to zero displacement with the residuary load only -0.12 kN, which demonstrates that the brace has excellent re-centering function. © 2017, Engineering Mechanics Press.
