【提要】 考虑周期效应,在定性分析结构季节温差应力变化规律的基础上,采用可复及不可复徐变的本构关系和继效流动理论,定量分析了混凝土结构的季节温差应力。通过与现场测试结果对比,得到了更精确的季节温差应力折减系数。
【关键词】 混凝土结构 温度应力 徐变
Research on Periodic Seasonal Temperature Stress in Concrete Structure/Han Chongqing1, Meng Shaoping2,Tang Hongyuan2(1 Institute of Architectural Design and Research Southeast University, Nanjing 210096, China; 2 College of Civil Engineering Southeast University, Nanjing 210096, China)
Abstract:Based on qualitative analysis of seasonal temperature stress in concrete structures, quantitative research is presented by adopting the recoverable and irrecoverable creep equation and aftereffect flow theory. The theoretical calculation results are approved by actual test, and more accurate temperature stress reduction coefficient is gained.
Keywords:concrete structure; temperature stress; creep
