对一个单层软钢结构的滞回力-挠度曲线进行了试验研究，得到了静、动荷载作用下的滞回力-挠度曲线。动态载荷包括施加到结构屋顶的约3cps的正弦力。最大纤维应变达到屈服应变的9倍。应变软化型的修改的钢中观察到在实验与随后的应变时效之间发生的实验。静态和动态滞回力-挠度曲线之间的差异被发现是小于在静态曲线的变化所造成的材料修改在重复加载。
Hysteretic force-deflection curves of a single-story laboratory structure made of mild structural steel were obtained experimentally for both static and dynamic loading conditions. The dynamic loading consisted of a sinusoidal force at about 3 cps applied to the roof of the structure. Maximum fiber strains up to 9 times the yield strain were realized. A strain softening type of modification of the steel was observed during the experiments with subsequent strain ageing occurring between experiments. Differences between static and dynamic hysteretic force-deflection curves were found to be smaller than changes in the static curves caused by the material modifications during repeated loading.
