我要一篇有中英文互译关于钢结构的论文。谢谢大家啊，急呢！！！！！！！！！！！！！

没有吗？

希望有的朋友帮助一下,谢谢!

一小段仅供参考:

Uncertainties in applied loads are introduced into the theory of optimization by use of ellipsoidal convex models.Mathematical derivations for quantifying uncertianty with the convex model are presented and are incorporated into an optimization computer algorithm.The algorithm is used in two design examples—a continuous two-span reinforced concrete beam and a steel ten-bar truss—with varying levels of uncertainty.Beam and truss designs are obtained under nominal loading,under uncertain loading while employing the convex model,and under uncertain loading using the maximum load condition.The overall cost of the optimal structures is minimized and the resulting designs are compared.The comparisons show that the design costs of the optimal designs produced under the convex model compare favorably to the design costs under nominal loading.However,the design costs associated with the maximum load condition are shown to significantly exceed both the costs associated with nominal loading and the costs associated with the convex models.ⓒ 1999 Elsevier Science Ltd.All rights reserved.

通过凸壳体模型的应用，加载的不确定性被引入最优化理论。凸壳体模型的量化不确定性用数学方法提出并同计算机优化计算法则相结合。这种计算法则被用于两个设计实例中—一个两跨的钢筋混凝土连续梁和一个由十根杆组成的钢珩架—用各种等级的不确定性。梁和珩架的设计是通过应用凸壳体模型进行名义加载，不定量加载，以及通过在最大加载条件下不定量获得的。最优化结构的总费用最小和最终的设计结果作比较得出。这些比较表明这些用凸壳体模型进行的最优化设计的设计费用明显优于在名义加载情况下的设计费用。然而，在最大加载条件下的设计费用明显超过了不管是同名义加载下联合下还是同凸壳体模型联合下的设计费用。

谢谢modal 。不过没有用啊，我要 整篇的，
