摘要
某公司机械楼钢结构在地基不均匀沉降作用下已严重损坏,结构安全和正常使用受到严重影响。在现场检测基础上分析归纳钢结构存在的主要问题,提出预应力和钢支撑相结合的加固方案;采用非线性有限单元法进行加固计算,结果表明效果良好。
Because of uneven foundation settlement,a mechanical building has been severely damaged,the safety and normal use of the structure have been affected seriously.Based on field detection,the main problems of the mechanical building are summarized,and a reinforce program is proposed which combines prestressed cables and steel braces.The nonlinear finite element method is used to calculate the reinforced structure,and the results show good reinforce effect.
