Description

内埋轻质材料体套管混凝土屈曲约束支撑 技术领域  Buried lightweight material body casing concrete buckling restraint support
本发明属于土木工程领域，涉及一种用于减小工程结构地震灾害影响的屈曲约束支撑及 其制作方法。  The invention belongs to the field of civil engineering, and relates to a buckling constraint support for reducing the impact of an engineering structure earthquake disaster and a manufacturing method thereof.
背景技术 Background technique
屈曲约束支撑是一种利用金属屈服耗散地震能量的装置， 由于其性能稳定、 制作方便、 成本低廉， 近年来得到了广泛的研究和应用。  Buckling restraint support is a device that uses metal yield to dissipate seismic energy. Due to its stable performance, convenient fabrication and low cost, it has been widely studied and applied in recent years.
目前，我国在工程上普遍应用的屈曲约束支撑大多由内填混凝土钢管约束部件和承受轴 向力的核心部件组成， 譬如已公开发明专利 (CN100560884C)中给出的技术方案。 约束部件 不直接承受轴向荷载，在外压力作用下可抑制核心部件的低阶屈曲，核心部件在拉力和压力 作用下全截面屈服，构件滞回曲线饱满。为保证在轴向压力作用下屈曲约束支撑不发生整体 失稳， 约束部件横截面应有较大的惯性矩， 所以约束部件材料用量很多， 最终导致整个屈曲 约束支撑自重较大。特别是当屈曲约束支撑应用于桥梁或大跨结构时，其约束部件的整体抗 弯能力需求会随着跨度增大而提高， 约束部件截面尺寸和自重也会增大， 给施工增加难度。 发明内容  At present, most of the buckling restraint supports commonly used in engineering in China are composed of inner concrete filled steel pipe restraining parts and core components bearing axial force, such as the technical solutions given in the published invention patent (CN100560884C). The constraining component does not directly bear the axial load. Under the external pressure, the low-order buckling of the core component can be suppressed. The core component yields under full tension and pressure, and the hysteresis curve of the component is full. In order to ensure that the buckling restraint support does not suffer from overall instability under axial pressure, the cross-section of the constraining component should have a large moment of inertia, so the amount of material used for the constraining component is large, which ultimately leads to a larger self-weight of the entire buckling constraint. Especially when the buckling restraint support is applied to a bridge or a large span structure, the overall bending capacity requirement of the restraining component will increase as the span increases, and the cross-sectional size and self-weight of the restraining component will also increase, which makes the construction more difficult.
