高层框剪结构综合楼加固处理及效果检验

REINFORCEMENT OF A HIGH-RISE COMPLEX BUILDING OF SHEAR FRAME STRUCTURE AND ITS EFFECT TEST

某科技综合楼加固工程中采用了多种加固方法,梁采用外粘钢板加固,用钢量少,造价低;外包钢加固法用于柱子的加固,施工方便。另外还采用了微细裂缝灌浆修复法和植筋法等。现场加载试验结果表明,该楼加固是有效的,满足现行国家规范的要求。

Several ways were employed in the reinforcement of a science and technology complex building. Beams were strengthened by sticking steel plates outside at less steel consumption and low costs; and columns were easily reinforced with steel enclosures. In addition, fine crack grouting and bar embedding were adopted in the reinforcement. Site load test shows that the building has been effectively reinforced, satisfying the requirements of the national code being in force presently.
