本文通过对某中学礼堂的可靠性鉴定,确定其可靠性,再针对其可靠性的不足,有针对性地按照使用要求进行加固改造。经可靠性鉴定提出结构加固概念设计,再通过空间模型结构验算,进行结构加固概念设计复核和进一步优化,最终形成切实可行的加固改造设计。这对于中小学老旧校舍建筑的鉴定和加固有重要参考意义,此类鉴定与加固改造设计的思路和方法可为同类型的工程提供参考。 Through the identification of the reliability of a middle school auditorium, this article confirms the reliability of the auditorium. In view of its lack of reliability, it reinforces and rebuilds according to the requirements. After the reliability appraisal, the conceptual design of structural reinforcement is put forward, and then through the checking of the structural model of the space model, the conceptual design of the structural reinforcement is reviewed and further optimized to finally form a feasible design of reinforcement and reconstruction. This is an important reference for the identification and reinforcement of the old and middle school buildings. The ideas and methods of such identification and reinforcement design can provide reference for the same type of project.
