钢结构加固修复的设计与施工

1． 结构加固修复设计应具备的基本资料
    （1）原有结构的竣工图和施工记录。当缺乏这些资料时，应具有结构现状的测绘资料；测绘时应注意并详细记录杆件和节点的偏心情况。
（2）原有结构的计算书。
（3）原有结构的损坏、缺陷和锈蚀等情况及其原因分析。
（4）原有结构的建造历史和使用情况。
（5）原有结构钢材的力学性能和化学成分。若缺乏原始资料时，应在原有结构上取样检验。
（6）实际荷载情况，应进行称量和实测。
（7）施工能力等。
2． 钢材的取样检验
Steel reinforcement and repair of Design and Construction

1. Structural reinforcement and repair should be designed to have the basic information
    (1) the original structure built drawings and construction records. When the absence of such data, should have the status of the mapping data structure; mapping should pay attention to a detailed record of the eccentric rod and node conditions.
(2) the calculation of the original structure of the book.
(3) damage to the original structure, defects and corrosion and the reasons for such analysis.
(4) the construction of the original structure of the history and use.
(5) the original steel structure, mechanical properties and chemical composition. Without the original data, the original structure of the sample should be tested.
(6) the actual loads, should be weighed and measured.
(7) construction capability.
2. Sampling and testing of steel
