中文摘要 | 本研究以圓柱試體試驗方式探討高強度混凝土受重覆載重下能量損失累積的行 為。共製作10*20cm之高強度與普通強度混凝土圓柱試體各18個,試體的平均極限抗壓強 度分別為1040kgf/cm 及230kgf/cm ,並據此進行單一載重比重覆載重及多重載重比重覆 載重試驗。試驗結果之分析顯示,高強度及普通強度混凝土試體在承受單一載重比S≧80% 之重覆載重下,其能量損失累積曲線不適用Miner's rule,不同強度試體在同一載重比下,其 能量損失累積行為之偏離Miner's rule具有極相近之趨勢。 |
英文摘要 | This paper investigates the behavior of energy damage accumulation of high strength concrete subjected to repeated loading. Eighteen 10*20 cm cylinder specimens were cast, with an average compressive strength of 1040kgf/cm and 230kgf/cm for high and normal strength concrete, respectively. Repeated loading with a monotonous loading-ration history or a multiple loading-ratio history was performed on the cylinder specimens. Test results revealed that:(1)Miner's rule is not applicable for the accumulative energy damage curve of high and normal strength concrete subjected to repeated loading with monotonous loading-ration, S, greater than or equal to 80%.(2)The accumulative energy damage behavior of those two kinds of strength concrete, under the same loading ratio, has almost the same degree of deviation as Miner's rule. |
