总纵强度耦合作用的船体板架强度计算方法

船体板架局部强度计算时，由于受到总纵弯曲的影响，实际上极架都是处在复杂弯曲状态，以往板架局部强度校核时未考虑这种影响。本文采用有限元方法原理，考虑总纵强度对局部强度的耦合影响，推导和发展了板架局部强度校核方法。对比计算表明，本方法可用于实用计算。

ON THE CALCULATION OF STRENGTH OF HULL GRILLAGE COUPLING WITH GIRDER'S BENDING

The overall longitudinal bending should be considered in the calculation of the local strength of hull grillage as the grillage is in fact subjected to combined bending,but this has not been taken into account previously.A new method for checking the local strength of plated grillage has been developed based on the principles of FEM. By comparing calculations it is indicated thatthe method may be used as a new means of checking the local strength for the purpose of dircect calculation of strength for naval ships.
