The invention belongs to the technical field of ship hulls, and relates to a DE method for improving the modulus and inertia moment of a cross section in a hull. A plurality of deck T-shaped longitudinal girders (E) are arranged below the port of the deck section I (B), and a plurality of deck T-shaped longitudinal girders (E) are arranged below the starboard of the deck section I (B); a plurality of deck T-shaped longitudinal girders (E) are positioned between the longitudinal wall I (F) and the longitudinal wall II (G); the distance between the section centroid position of the T-shaped longitudinal girder (E) of the deck and the neutral axis (D) of the middle cross section is h; and the distance h from the section centroid position of the T-shaped longitudinal girder (E) of the deck to the neutral axis (D) of the middle cross section is greater than the distance L from the platform plate to the neutral axis (D) of the middle cross section. According to the method for improving the modulus and the inertia moment of the transverse section in the ship body, the modulus and the inertia moment of the transverse section in the ship body are increased by increasing a small structural area, the ship body is light in weight, the total longitudinal strength requirement is met, and steel does not need to be additionally replaced.

    本发明属于船舶船体技术领域DE提升船体中横剖面模数和惯性矩的方法。在甲板分段Ⅰ(B)左舷下方设置多根甲板T型纵桁(E),在甲板分段Ⅰ(B)右舷下方设置多根甲板T型纵桁(E);多根甲板T型纵桁(E)位于纵壁Ⅰ(F)和纵壁Ⅱ(G)之间;甲板T型纵桁(E)截面形心位置到中横剖面中和轴(D)为距离h;甲板T型纵桁(E)截面形心位置到中横剖面中和轴(D)的距离h大于平台板到中横剖面中和轴(D)的距离L。本发明所述的提升船体中横剖面模数和惯性矩的方法,利用较小的结构面积增加,使得船体中横剖面模数和惯性矩得到增加,船体实现轻量化,满足总纵强度要求,不需要另外更换钢材。
