地震后某中学综合楼的加固设计与施工方法
|
摘要
汶川地震后,根据最新的标准,灾区学校、医院等公共建筑需提高一级进行抗震设防,故需对原结构按新规范标准重新进行计算复核以及抗震加固。重点阐述了抗震加固设计的方法和步骤,详细介绍了复合砂浆网和增大截面法加固技术在加固地震灾区建筑中的应用以及施工中的注意事项。结合地震灾区一实际工程对抗震加固和施工技术做全面的论述,供类似工程的加固设计及施工参考。
After Wenchuan earthquake,according to the newest code,some public buildings like school building,hospital in earthquake effected regions must rise a grade for seismic design,so recalculation and seismic reinforement of the original structures must be conducted accordance with the new codes.This paper focuses on the seismic strengthening design methods and steps,and introduces the application of ferrocement and section enlargement to buildings in earthquake areas.Based on a practical project in earthquake effected regions,this paper can supply some good references for seismic strengthening design and construction technology of similar projects.
