This paper presents the applicability of an estimation method for the experienced maximum load and displacement responses by small load increment, For the expansion of the proposed method, three reinforced concrete column specimens were tested under dynamic loading and a comparatively large scale specimen was tested under static reversedcyclic loading. The test results indicated that the relationships between the secant stiffiness under the small load increment and the equivalent secant stiffness corresponding to the maximum experienced response were represented by a logarithmic function. They also indicated that the relationships between the displacement caused by small load increment and the experienced maximum displacement of the damaged columns were expressed by an exponential function. From the test results the applicability of the proposed method were examined. As a result, it was found that the proposed method was applied to specimens under dynamic loading and comparatively large scale specimens under static reversed cyclic loading. However, furthermore experimental and analytical studies are needed to establish a more reliable estimation method.
