摘要目前鋼筋混凝土在柱筋設計方面，經常以
試誤法設計鋼筋量。其過程較為複雜，因而程式發展方面顯得比較困難。
故本文自另一個方向，以數學觀點來設計鋼筋量。 首先根據鋼筋混凝
土力學上的特性，建構數學關係，接著以數值分析中之二分逼近求根法，
解出中性軸位置，接著再計算鋼筋量。 文中並以此法發展程式。先讀
取ETABS程式分析前後檔案中，有關柱設計之基本資料及斷面力，然後設
計柱筋量。其輸出結果列於附錄，並將其所求之解和CONKER程式所得結果
作一比較。比較中並可顯示出本文之方法，可得一更準確且經濟之結果。

ABSTRACT Trial and error method is the
common method usedfor the reinforced concrete column design.
Theprocedure used in this method is quite complicated,therefore
it is not suitable for the computeralgorithm. Another approach
is used in this study to solve this problem. Mathematical
equations were first derived by thereinforced concrete basic
assumptions. Then thenumerical bisection method was used to find
thelocation of neutral axis. Reinforced area can beobtained
accordingly. A program was developed in this study also.
Thefirst part can read the ETABS force output fileautomatically.
Then the models developed in thisstudy were used to design
reinforcement for eachcolumn. The obtained results were compared
to theresults obtained from CONKER program. The comparison shows
that the models developed in this study is more accurate and
economical.
