Abstract
Transient response of a pontoon type VLFS subjected to moving load due to airplane landing/take-off is investigated. An approximate solution of free plate natural vibrations, based on a new set of mathematical modes consisting of ordinary products of beam modes and their combinations as additional (extraordinary) modes, for which the natural frequencies are analytically determined using the Rayleigh's quotient, is proposed. The system of modal hydroelastic equations, governing the floating airport forced vibrations, is derived using the Lagrange equation of the second kind and a simplified solution procedure is outlined. Airplane excitation loads are discussed and a new formulation of moving load is proposed and validated. The obtained results are compared with known ones from relevant literature.
