確定了船體梁整體破壞時的剖面應力分佈之後，關鍵在於確定板架的極限屈曲強度。本文充分考慮了在縱向彎曲、橫向壓力作用下加筋板可能發生的幾種破壞模式，即板架的整體屈曲破壞、樑柱形式的破壞、筋的側傾、腹板的屈曲並同時考慮了初始焊接殘余應力、初撓度的影響，使其更精確的計算加筋板的屈曲強度。對于加筋板中加強筋腹板的局部屈曲，採用解析法推導出筋的腹板的撓度方程及其邊界條件，求解相應的方程，從而計算出腹板的局部屈曲應力。By low - cycle and reverse horizontal loading test, their properties including strength property, deformation property and energy property are studied. we study the loading characteristic values ; the property of hysteretic curve and skeleton - frame curves ; the ductility property and stiffness degradation. lastly, based the data got from the test, this paper analyses and value the seismic behavior of every members
