Vibration Analysis of Horizontally Curved Beams with Warping Using DQM

摘要: The differential quadrature method (DQM) is applied to computation of the eigenvalues small-amplitude free vibration for horizontally curved beams including a warping contribution. Natural frequencies are calculated single-span, curved, wide-flange uniform having range nondimensional parameters representing variations in stiffness, torsional radius curvature, included angle curve, polar mass moment inertia, and various end conditions. Results compared with existing exact numerical solutions by other methods cases which they available. DQM provides accuracy even when only limited number grid points used. In addition, results given cantilever that has one clamped end; no previous known this case. Finally, parametric presented dimensionless form.
