某中学礼堂可靠性鉴定与加固设计探索 魏常宝,吴生祥,王正东* (甘肃土木工程科学研究院,兰州 730020) 5 10 15 20 25 30 35 40 摘要:本文通过对某中学礼堂的可靠性鉴定,对这类型中小学老旧校舍建筑进行可靠性评定, 确定其可靠性,再针对其可靠性的不足,有针对性的对这类型建筑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。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。礼堂柱采用外包混凝土法加固,梁根据不同情况采用部 分外包混凝土、部分高强不锈钢绞线聚合物砂浆面层法加固,加固效果良好。 关键词:礼堂;可靠性;鉴定;加固;设计 中图分类号:TU375 A auditorium reliability appraisal and reinforcement design of middle school Wei Changbao, Wu Shengxiang, Wang Zhengdong GanSu Civil Engineerring Science Research Academe, LanZhou 730020 Abstract: Through to reliability evaluation of a middle school auditorium in this article, construction for reliability assessment, and determine its reliability for this type of primary and old buildings of a middle school. In view of its reliability is insufficient, targeted to this type of construction and according to the use requirements of reinforcemen. Put forward the reliability evaluation of structural strengthening concept design, and then through the space model structure calculation, structure strengthening concept design review and further optimization, and finally form a practical and feasible reinforcement and reconstruction design. This kind of appraisal and reinforcement and reconstruction design train of thought and method for the same type of project to provide reference.The auditorium column using outsourcing concrete method to reinforce, beam, according to the different conditions using part of the outsourcing concrete, part of the high strength stainless steel stranded wire polymer mortar layer method to reinforce, strengthening effect is good. Keywords: auditorium; reliability; appraisal; reinforcement; design 0 引言 2008 年汶川地震后,全国各个地区中小学校舍安全提上议事日程,由于各个地区中小 学校舍建筑大多为旧建筑,建筑的安全性已经达不到汶川地震后的安全要求。2010 年后新 的抗规[1]发布并实施,现有的老旧建筑的安全性已经达不到现行抗规要求(尤其是中小学校 舍建筑),需要进行可靠性(或者安全性、抗震等)鉴定和相应的加固改造,使得该批不能 拆除的老旧建筑的安全性达到要求,中小学老旧建筑的加固改造刻不容缓。通过对中小学老 旧校舍建筑的可靠性鉴定,确定其可靠性等级,针对建筑使用要求进行相应的加固改造,使 其安全性和实用性达到规范要求,能够在设计后续使用年限内安全可靠
