摘要

本文為探討多種最佳化程序方法如何應用於結構設計，主要提出三種最佳化程序之方法，應用至兩種截然不同之案例。第一部份會介紹兩種最佳化程序方法理論：樓層相對位移均勻導向最佳化方法和複合形法，分別對一棟六層樓含BRB鋼造斜撐構架案例和一棟三十四層樓含BRB鋼造斜撐構架案例，針對挫屈束制斜撐構件BRB(Buckling Restrained Brace)提出相對應的最佳化程序，以更換斜撐BRB構件的斷面積為最佳化的對象，設計其構件尺寸。而最佳化程序的主要兩個關鍵即滿足目標函數和束制條件。第二部份為了推估混凝土塊體碰撞之碰撞力公式，將利用[Q][U]分解法理論和迴歸程序進行非線性迴歸分析，模擬得一考慮多項參數之碰撞衝量，經由碰撞衝量、恢復係數和碰撞力、碰撞後速度之關係，建立一合理塊體碰撞之碰撞力公式。

In this paper, the optimization procedures of the structures analyses are adopted to apply to structure design. Three procedures of optimization method are used to study two cases of structures dynamics analysis. In the first parts of the article, two theorems of the optimization procedures are introduced. For examples, the story relative displacement uniformly directive method and complex method are adopted to compute the section size of the buckling restrained brace (BRB) in the 6-story building and 34-story building. It is according to the optimization procedure. The Optimization procedure must be satisfied objective function and boundary condition.
In the second parts of the article, the formulation of the collision force in reinforced concrete structures is estimated. From the resulates of the experiment, the [Q][U] decompose method and nonlinear regression can be used to find the formulation of the related impulses. In addition, according to the related impulses can be found the reasonable formulation for the coefficient of restitution, collision force, and collision velocity in reinforced concrete structures.
