一、引言JT402 1-79船体构件变形修理更换标准是一个新制订的标准。它通过着重对横结构式的海船的强力甲板及船底板的平均挠度及最大挠度的试测分析和理论计算提出了船体变形的使用限制条件。本标准制订的依据
I. INTRODUCTION JT402 1-79 hull component deformation repair replacement standard is a new standard. It puts forward the restrictions on the deformation of the hull by the test and analysis and theoretical calculation of the average deflection and the maximum deflection of the strength deck and the ship’s bottom of a horizontal structure ship. The basis for the development of this standard
