某高校体育馆加固与改造
|
摘要
汶川地震后,教育部要求各高校对在本次地震中受损的建筑进行抗震加固处理,某体育馆为其中一例。由于该体育馆为大跨度木屋架结构,不满足现行规范要求,故加固方案一度难以确定。经多次分析、论证、对比、抗震验算后,最终对原砖柱进行了外包钢筋混凝土加固,对墙进行了外包钢筋网加固,并用新建钢屋架代替了原木屋架。该体育馆经过加固改造,既符合了现行规范要求,又明显增强了原结构的抗震性能。
After Wenchuan earthquake,the Ministry of Education required all the universities to reinforce the buildings damaged in the earthquake.A gymnasium was one example of them.The gymnasium is a large-span woodern roof truss,not meeting the current standard requirements,so it was once difficult to determine the reinforcing scheme.After many times anylsis,demonstration,comparation and seismic check,in the end,we chose the reinforcing scheme of wraping the brick columns with reinforced concrete,reinforcing the walls with steel mesh,in the same time,insteaded the woodern roof truss with a new built steel roof truss.After the reinforcement and reconstruction,the gymnasium not only met the current standards,but also stregthened the anti-seismic performerce of the original structure obviously.
