摘要
人防工程平战功能转换是人防工程建设和发展的重要指导思想,人防工程主体结构加固改造必须满足可靠、迅速和经济三大指标,后加柱技术是人防工程主体结构提高结构抗力等级的比较实用的方法,木柱是一种易加工安装且经济可行的后加柱形式.采用无梁板结构,通过水囊逐级加载试验,分析了板、墙和柱上混凝土和构件内钢筋的应力-应变关系及可能的破坏特征.试验结果表明,木柱可用于人防工程主体结构的加固改造.
The function convertion between the peace and the war about the people's defenses is one of the important ideasThree main targets(trustiness,speed and economy) must be satisfiedPostreinforced column technology is an effective method in boosting the level of resisting forceThe wooden column is easily processed and fixed,which has become one sort of postreinforced columnsThe paper analyses relation between stress and strain on concrete and steel in three sorts of components(plate,wall and column)and failure modes through waterbursa loading experiments in purlinless roof structureThe results show that the wooden column can be applied to the reinforcement the main structure in the people's defenses
