Five wave load approachingdirections are selected based on the structural symmetry: 0°, 45°, 90°, 135°, 180°, and the mostcritical load cases in which other environmental loads are applied in the same direction with wave load areadopted in the calculation.
The author gives a complete analyses on its basic theory, classification of structure strength of ship, wave load forecast, structure analysis technology, safety criterion for structure strength, fatigue strength, reliability analysis, and prospect of the structure strength research, etc.
The numerical results show that the increase on the porous coefficient of outer column and the water depth inside the cylinder will reduce the wave elevation around the cylinder and the wave load on it.
We have made the wave test acting on the cylinder shell construction with large diameters. On the basis of test, the study on the calculations of wave force and its moment acting on the cylinder shell construction of large diameters during the construction period were given by multiple linear regression analysis, thus the simple feasible formula for calculating wave load was obtained.
The tuned liquid damper(TLD) is applied to control the structural vibration of a wave-permeable breakwater,and the dynamic response equation of the TLD-equipped wave-permeable breakwater under random wave load is formulated. Then,the influences of TLD parameters on the control effect are discussed on the basis of some calculation examples.
Research purposes: The difference between a submerged floating tunnel(SFT) and a traditional submarine tunnel is that the former is subjected directly to wave and current action, and the wave action,which varies as a function of time,will cause dynamic effect in the SFT. Therefore,the dynamic response analysis of the structure under wave load should be inevitable in designing the project.
The model of rock-mass shattering is constructed with due regard for the wave load attenuation governed by the geometrical divergence of wave and irreversible losses in rock.
Dependence of spall strength of metals on the amplitude of a shock-wave load
We also discuss the stochastic significance of the estimated value and nonlinear nature of the peak distribution, in addition to the effects of the ship speed and wave heading on the wave load estimation.
The nonlinear dynamic response of TLP under random sea wave load is necessary for determining the maximum deformations and stresses.
