Hydroelastic Analysis of Floating Performance Stage at Marina Bay, Singapore

Abstract

This paper presents the hydroelastic analysis of the floating performance stage that was constructed at the Marina Bay. The challenge posed in the hydroelastic analysis was the modeling of an equivalent plate that captures the dynamic flexural behaviour of the floating stage. By using a plate model with plate strips along the connecting lines of the floating stage, their Young’s moduli and Poisson’s ratios are adjusted so that the free vibration frequencies and mode shapes of the equivalent plate model match the results of the rigorous finite element model of the floating stage. The analysis shows that the hydroelastic response of the floating structure is relatively mild due to the calm waters in the Marina Bay when compared to the static bending response from imposed loads.
