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。 -

According to the design theory of the cable - stayed bridge and to the feature of the cantilever construction the authors propose a construction control method called optimum completion state method ( ocsm ) for rc cable - stayed bridges in the proposed method, the optimum completion state is regarded as the final target of the construction control, and the optimum construction state at each construction stage is taken as the technical route the key of the method is to properly choose or adjust the cable forces the objectives function of optimization is to minimize the elevation error of the girder under the constraint condition that the internal forces ( bending moments ) of the girder are bounded the optimization variables are the cable forces on the basis of the above principles, a optimum model for a construction step is established and cable force adjustments can be found for each construction step in this model, the creep and shrinkage effects of concrete have been considered a bridge example is given which shows that the final state of the bridge is very close to the design aim and that this method is much better than the so - called double - control method the example is a good illustration of the soundness and practical value of the proposed method
