Prediction of Circular Frequency of Precast Concrete Piles with Distributed Mass by Resonance Moment–Displacement Approach
Abstract: This paper presents the results of circular natural frequency of single piles from critical buckling load by resonance moment-displacement approach. The support end conditions considered are pinned-pinned, fixed-fixed, and fixed-pinned respectively. It was assumed that resonance moment occurs when the bending moment diagram is made equal to zero at the supports while the resonance displacement is the sum total deflections resulting from the system reduction to an equivalent pinned-pinned system. …
