摘要:
提出短屈服段屈曲约束支撑(SC-BRB)，以解决在罕遇地震下钢框架结构残余层间位移角过大导致震后支撑更换困难问题.采用有限元对SC-BRB的滞回性能进行研究，分析参数对支撑的影响规律.结果表明：屈服段长度对BRB的滞回性能影响较大，集中因子α减小后，SC-BRB能较早地进入耗能阶段，拥有更高的耗能效率，但SCBRB的低周疲劳性能较差；SC-BRB具有足够的耗能能力；增加内核板的宽厚比可减小外约束的用钢量，但宽厚比的增加，会导致支撑低周疲劳性能和延性降低，建议内核宽厚比限值取15；外约束所需的最短长度随着集中因子α的增大而增大，建议取屈服段长度和0.5倍支撑总长中的较大值；建议SC-BRB选取摩擦系数不大于0.1的无粘结材料.
Abstract:
The paper, the short-yielding-section buckling-restrained brace(SC-BRB) is proposed to solve the difficulty of brace replacement due to excessive deformation and large residual inter-layer drift of steel frames under extreme seismic loading. Finite element method is applied to study the hysteresis behavior of buckling-restrained braces with different yielding section lengths. The influence of key parameters on the brace is analyzed. The results demonstrate that the yielding section length has a great influence on the hysteresis performance of BRB. After decrease of the concentration factor α, BRB can enter the plastic energy consumption stage earlier,at the same time can have higher energy consumption efficiency, but SC-BRB has poor low-cycle fatigue performance; SC-BRB has sufficient energy consumption capacity. The amount of steel used for external restraint can be reduced with the larger ratio of width to thickness in the core plate. However, low cycle fatigue performance and ductility of the core can be ineffective if the ratio of width to thickness is extreme. It is suggested that the ratio of width to thickness is no more than 15. It is also recommended that the shortest external restraint length is 1/2 of the total brace length to avoid the large stress intensity in the brace. Finally, since the friction has a significant effect on the performance of SC-BRB. Unbounded materials with friction coefficient less than 0.1 may be selected between the BRB core plate and the outer restraint.
