Simplified one mass system of column with weakly nonlinear M-φ relationship is modeled by Duffing equation and some typical behaviors of Duffing equation are shown in numerical results. And comparison of phase plane of horizontal displacement between actual results of dynamic response of RC column and the results of Duffing equation has a good coincidence in the case of weakly nonlinear region of M-φ curve., application/pdf}, pages = {461--468}, title = {M-φ曲線が軟化する柱部材のDuffing方程式による曲げ振動解析}, volume = {1}, year = {} }
