| 摘 要： | 本文在带暗支撑剪力墙研究的基础上,进一步提出了带暗支撑核心筒体,通1/6缩尺的1个带暗支撑筒体结构和1个普通筒体结构的低周反复荷载试验,比较分析了它们的承载力、刚度、延性、滞回特性、耗能能力及破坏机制。试验表明,带暗支撑筒体比普通筒体的抗震性能明显提高。

| Abstract: | In this paper, reinforced concrete core walls with concealed bracings is put forward based on the study of RC shear wall with concealed bracings. Through the contrast experimental study on one 1/6 scale normal reinforced concrete core walls and one 1/6 scale reinforced concrete core walls with concealed bracings under the low cyclic loading, the effects of concealed bracings on the bearing capacity, stiffness, ductility, energy dissipation, hysteresis property and failure phenomena of reinforced concrete core walls are discussed. The experiment shows that concealed bracings are able to improve greatly the seismic behavior of reinforced concrete core walls. |
