The statistical background of wave-induced bending moment, i. e. spectral density, transfer function, correlation function, distribution function, and their applications has been reviewed. The shortterm distribution of stress amplitudes-Rayleigh function, the long-term distribution of stress amplitudeslog-normal function, and the probability distribution of impact-induced bending moment-normal function have been introduced respectively. Several methods for determination of design standard of bending moment are presented, such as the design standard of bending moment may be determined by the probability of joint distribution of wave-height and wave-length at severe sea state, or by using' the rule of "3σ"or "4σ" (σ-standard deviation) adopted from statistics. After consideration of problems existing in statistical analysis of wave-induced bending moment of ships, the following conclusions are made: (1) The investigation of design standard of wave-induced bending moment is based upon the strength of an actual ship. (2) Full-scale ship trials of short-term and long-term must be carried out. (3) The actual distribution of extreme value of high stress, and the analysis of spectrum of wave-induced bending moment have to be studied.

This report gives a method for computation of wave-induced, bow-flare slamming and bottom impact bending moments in time domain.The wave model assumed is the superposition, in random phases, of regular waves of various amplitudes and frequencies in accordance to a given sea spectra. Then, the relative motions and wave-induced moments expressed as time histories may be represented by the super-position of corresponding regular-wave responses in the same random phases.The bow-flare slamming moment is substantially a correction to the wave-induced moment according to the linear theory by consideration of non-linear buoyancy forces and inertial hydrodynamic forces as suggested by Kaplan. In the determination of slamming load, Smith correction is considered.It is known that the magnitude of bottom impact load cannot be evaluated accurately by the momentum theory of variation of water added mass (especially for ships with wide flat bottom). In this report, the well established ship motion calculation is combined with the informations about experimental slamming pressure values given by Ochi et al. The essential points are: l)Using ship motion time histories, determine the time instants satisfying the slamming condition r =T, r≤ - r*, and the corresponding relative velocities; 2 ) according to the magnitudes of relative velocities and section contours, determine the spatial and time distribution of slamming pressure using available experimental results (such as max. pressure, duration etc.); and 3 ) integraing along each section the vertical pressure components at corresponding time instants, which gives the bottom impact load time-space distribution Pbi (xb, t ).The ship girder whipping responses are computed by the well-known modal method of analysis.By the above procedure, two ships A & B of different forms are tabulated to compare the computed and trial results. Ship A is a fast ship with bulbous stem and a large bow flare, while ship B is a full ship with flat bottom and light draft. It is seen that the agreement is satisfactory in general.

本文给出了在时域内计算船体波浪弯矩、外张砰击弯矩和底部砰击弯矩的一种方法。 其中波浪模型依所给海浪谱取为由许多不同频率和振幅的规则波按随机相位相加而成。 在确定外张砰击的载荷公式中,本文考虑了Smith修正。 本文采用把比较成熟的船舶运动计算和由越智和夫等人在底部砰击压力试验方面提供的资料相结合的方法来确定底部砰击载荷。 按上述方法对两艘不同船型作了计算,并分别与其试验值进行了比较,得出比较满意的结果。
