DYNAMIC LOADS FROM WAVE, THE IMPACT ON SEA STRUCTURES
Keywords:
stiffness of flexural members, limiting opening angles coefficients bent elements, instantaneous pulseAbstract
We consider the dynamic loads arising from the wave processes on offshore structures through
the pile foundations of large cross section with the "hard core " . The laws of dynamic load changes in
time from the wave processes are shown in a graph. These dynamic load over time θ for pile foundations
can be arbitrarily taken as a momentary impulse or a short-acting form.
It is established that the action of short-term dynamic loads design of offshore structures to be
calculated for two limiting conditions. Flexural rigidity defined elements , limit opening angles , the
coefficients of flexural members, etc.
