DB13(J)∕T 8394-2020 高延性混凝土加固砌体结构技术标准
简介
前 言
为了促进结构加固工程领域的技术创新，规范高延性混凝土加固技术在河北省砌体结构加固工程中的应用，由河北省建筑科学研究院有限公司、西安建筑科技大学会同有关单位编制本标准。
本标准编制过程中，编制组调查总结了近年来国内外有关高延性混凝土的工程应用和实践经验，采纳了该领域内的最新科研成果，经广泛征求意见，反复修改，最终经审查定稿。
本标准的主要技术内容是∶1 总则;2 术语和符号;3 基本规定;4 材料;5加固设计;6构造规定∶7施工∶8质量验收;9 农村砌体房屋加固∶附录。 目次 1 总则.................................................................................................1 2 术语和符号.................................................................................... 2 2.1 术语········································································2 2.2 符号········································································3 3 基本规定........................................................................................ 5 4 材料.................................................................................................7 4.1 一般规定······································································· 7 4.2 材料性能······································································· 7 4.3 计算指标······································································ 10 4.4 配合比设计··································································· 10 5 加固设计...................................................................................... 12 5.1 一般规定······································································ 12 5.2 砌体抗压加固································································ 12 5.3 砌体抗剪加固································································ 16 5.4 砌体抗震加固································································ 17 5.5 抗震能力计算································································ 18 6 构造规定...................................................................................... 25 6.1 一般规定······································································ 25 6.2 抗压加固······································································ 28 6.3 抗剪和抗震加固····························································· 30 6.4 抗震构造措施································································ 31 6.5 砌体构件局部加固·························································· 33 7 施工...............................................................................................36 7.1 一般规定······································································ 36 7.2 施工准备······································································ 39 7.3 季节性施工··································································· 39 8 质量验收...................................................................................... 41 8.1 一般规定······································································ 41 8.2 主控项目······································································ 44 8.3 一般项目······································································ 46 8.4 高延性混凝土加固砌体工程竣工验收............................................. 49 9 农村砌体房屋加固...................................................................... 52 9.1 一般规定······································································ 52 9.2 基本要求······································································ 52 9.3 加固方法······································································ 53 9.4 施工······································································ 61 9.5 质量验收······································································ 62 附录 A 高延性混凝土弯曲韧性试验方法.................................... 66 附录 B 高延性混凝土力学性能快速检验方法............................ 70 附录 C 农村房屋加固工程施工质量验收记录表........................ 72 本标准用词说明................................................................................ 74 引用标准名录.................................................................................... 75 条文说明.............................................................................................76
