PAGE PAGE 3 防屈曲支撑构件技术研究 防屈曲支撑结构 摘要 本文针对加强土木工程结构减震技术，进行研究和开发，具体设计了一种建筑结构构件，特别是一种用于减震耗能的防屈曲支撑。本实用新型防屈曲耗能支撑结构是在其中增设了固体阻尼材料层，吸收建筑系统外部输入能量的能力大大增强，轴心处钢板的承载状况得到了明显改善，对外部约束的强度要求大大降低，因此不需要在混凝土层外部设置钢管进行强化约束，极大的简化支撑构件的结构。 本项目为科技发明制作，结构简单，减震耗能效果显著，可以广泛应用于采用钢与混凝土组合结构的大型土木工程建筑，特别是高层建筑，它可以有效提高建筑的抗震安全性能，有利于进一步延长建筑的使用寿命，其经济效益与社会效益十分显著。 关键字：防屈曲支撑结构；减震技术；阻尼材料层。 Anti-buckling support structure Abstract In this paper, civil engineering structure to enhance shock absorption technology, research and development, specific design elements of a building structure, in particular, is a shock absorber for the energy of the anti-buckling support. Anti-buckling of the utility model to support the structure of energy consumption is a solid in which the additional layer of damping material to absorb external input of energy building systems the ability to greatly enhance, the axis of the bearing plate Office has been marked improvement in the situation, the intensity of external constraints greatly reduce the requirements and therefore do not need to set up the external layer of concrete to strengthen the bound by steel, which greatly simplified the structure of the support component. The project for the production of scientific and technological inventions, simple structure, effective shock absorption energy can be widely used in steel and concrete composite structure of large civil engineering construction, especially in high-rise buildings, which can effectively improve the seismic safety performance of construction is conducive to further extend the service life of buildings, the economic and social benefits are very significant. Keywords: Anti-buckling support structure; damping technology; damping material layer. 目录 技术领域概述·····················································5 背景·····························································5 当前国内外研究水平概述···········································5 3.1国外研究·····················································5 3.2国内研究··························
