【提要】 考慮周期效應(yīng),在定性分析結(jié)構(gòu)季節(jié)溫差應(yīng)力變化規(guī)律的基礎(chǔ)上,采用可復(fù)及不可復(fù)徐變的本構(gòu)關(guān)系和繼效流動理論,定量分析了混凝土結(jié)構(gòu)的季節(jié)溫差應(yīng)力。通過與現(xiàn)場測試結(jié)果對比,得到了更精確的季節(jié)溫差應(yīng)力折減系數(shù)。
【關(guān)鍵詞】 混凝土結(jié)構(gòu) 溫度應(yīng)力 徐變
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.
