摘要
鋼筋混凝土雙向柱之分析設計上較為困難,早期多以經驗法或近似法為之,隨著電腦及程式運算不斷的發展,許多基於規範之設計和驗算方法不斷出現。本研究對多年來各方所提出之方法,作一整理與歷史回顧,最後以ACI318-11規範為準,檢核不同方法的結構設計結果,並比較探討之。
研究中所介紹的方法,包括;(1). Bresler’s 近似法(2). Etabs 設計法(3). 準牛頓法(4). 類神經網路法。並將原本為人工計算之Bresler’s近似法,改為計算機程式化來執行。
分析結果顯示,使用準牛頓法以及類神經網路法所得到之結果最為理想,因此建議在工程上分析及設計鋼筋混凝土雙向柱時,應參考此兩種方法來進行模擬及分析。此外,雖然使用Etabs設計法及Bresler’s 近似法所得之結果,比準牛頓法所得較為保守。受到軸力較大彎矩較小的狀況下,使用Etabs 設計法準確性較差;但resler’s 近似法所得之結果,則恰恰相反。使用時必須注意。

The analysis and design of reinforced concrete columns under biaxial bending are difficult. Over the years various design and checking methods have been developed. This thesis presents a historical study on different methods for strength estimation of such structural elements according to ACI design code. A comparison of design results according to ACI318-11 via different methods is also made.
Four design methodsstudied includes: (1). Bresler’s Approximation method, (2). Etabs method, (3). Direct iterative method, and (4). Neural network method. The first method is the only one which is applied manually. The author also proposed a handy procedure to make it work in computer environment.
This study revealed that the quasi Newton design and the neural network design methods present closest results. If available, these two methods should be used in engineering practices.
The Etabs design and reciprocal load design method are conservative andunconservative respectively compared to the quasi-Newton method. Moreover for columns with a large nominal axial strength and small bending moment Etabs design method is less accurate. On the other hand the reciprocal load design has good results for that kind of columns and less for columns subject to a low nominal axial strength. The author recommends the use of Etabs design method for columns with low to intermediate axial force and reciprocal load method for columns having a large axial force.
