What may foresee will be the 21st century, the human building also by the concrete structure, the steel structure, the bricking-up structure and so on primarily, the present stage I will think us in the structure reinforcement this aspect research should also take this as the main breakthrough direction. 1 Concrete structure reinforcement Concrete structure's reinforcement divides into the direct reinforcement and reinforces two kinds indirectly, when the design may act according to the actual condition and the operation requirements choice being suitable method and the necessary technology. 1.1 the direct reinforcement's general method1）Enlarges the section reinforcement law Adds the concretes cast-in-place level in the reinforced concrete member in bending compression zone, may increase the section effective height, the expansion cross sectional area, thus enhances the component right section anti-curved, the oblique section anti-cuts ability and the section rigidity, plays the reinforcement reinforcement the role. In the suitable muscle scope, the concretes change curved the component right section supporting capacity increase along with the area of reinforcement and the intensity enhance. In the original component right section ratio of reinforcement not too high situation, increases the main reinforcement area to be possible to propose the 混凝土结构配筋设计摘要：在长期的自然的环境下使 用环境的功能结构，其功能减弱不 可避免地渐渐地，我们的结构工程 的责任不只是必须完成建设前期项 目工作，但必须能够科学评价结构 的破坏目标法律和程度，并采用有 效的方法保证结构的安全使用，该 结构加固将成为一个重要的工作。

什么可以预见将是 21 世纪，人类建 筑的混凝土结构，钢结构，砌体式 结构等为主另外，现阶段我会觉得 在结构加固我们这方面的研究也应 借此作为主要的突破方向1 混凝土结构加固混凝土结构的加固分为直接加固， 并 加强间接两种，在设计时可根 据实际条 件和使用要求选择适宜的方 法和必要的技术1.1 直接加固的一般方法1）放大截面加固法添加混凝土现浇钢筋发生水平弯 曲 受压区混凝土构件，可能会增 加部分有效高度，扩大截面面积，从 而提高了组件的右侧部分反弯，斜截 面抗切割能力部分刚度，起到加固补 强的作用在适当的范围，改变混凝土弯 曲的组件的右侧部分配套能力，随着 钢筋面积和强度的提高增加在原来plateau component right section anti-curved supporting capacity effectively. Is pulled in the section the area to add the cast-in-place concrete jacket to increase the component section, through new Canada partial and original component joint work, but enhances the component supporting capacity effectively, improvement normal operational performance. Enlarges the section reinforcement law construction craft simply, compatible, and has the mature design and the construction experience; Is suitable in Liang, the board, the column, the wall and the general structure concretes reinforcement; But scene construction's wet operating time is long, to produces has certain influence with the life, and after reinforcing the building clearance has certain reduction. 2) Replacement concretes reinforcement lawThis law's merit with enlarges the method of sections to be close, and after reinforcing, does not affect building's clearance, but similar existence construction wet operating time long shortcoming; Is suitable somewhat low or has concretes carrier's and so on serious defect Liang, column in the compression zone concretes intensity reinforcement. 3) the caking outsourcing section reinforcement lawOutside the Baotou Steel Factory reinforcement is wraps in the section or the steel plate is reinforced component's outside, outside the Baotou Steel Factory reinforces reinforced concrete Liang to use the wet outsourcing law generally, namely uses the epoxy resinification to be in the milk and so on methods with to reinforce the section the construction commission to cake a whole, after the reinforcement component, because is pulled with the compressed steel cross sectional area large scale enhancement, therefore right section supporting capacity and section rigidity large scale enhancement.This law also said that the wet outside Baotou Steel Factory reinforcement law, the stress is reliable, the construction is simple, the scene work load is small, but is big with the steel quantity, and uses in above not suitably 的组件的右侧部分钢筋的比例不太高 的情况，增加了主要加固面积有可能 提出的高原组件的右侧部分抗弯曲能 力，有效地支持。
