通过对两根钢筋混凝土柱构件进行循环往复加载试验，对比分析了在快速加载条件下和拟静力加载条件下构件的力学性能，试验结果表明，荷载加载速率的增大会提高钢筋混凝土柱构件的承载力，快速加载条件下柱构件的延性较拟静力条件下差。
通過對兩根鋼觔混凝土柱構件進行循環往複加載試驗，對比分析瞭在快速加載條件下和擬靜力加載條件下構件的力學性能，試驗結果錶明，荷載加載速率的增大會提高鋼觔混凝土柱構件的承載力，快速加載條件下柱構件的延性較擬靜力條件下差。

Through the circles loading test on two reinforced concrete column structure, this paper comparative analyzed the mechanical properties of structure under fast loading conditions and quasi static loading conditions, the test results showed that the increase of loading rate would im- prove the beating capacity of reinforced concrete column structure, the ductility of column structure under fast loading was lower than under pseu- do-static conditions.
