拉力構件我們常忽略眼桿(eyebar)、樞接構材(pin-connected plate)部分，所以本研究探討相關公式與限制條件並加以整理，分析其設計步驟，比較而選得一較佳斷面以符合經濟效益。柱子在結構系統中是非常重要的受壓構件，本研究執行鋼柱構件之彈性與非彈性分析與設計，以獲得較經濟之設計斷面。目前之AISC(2005, 2010)規範整理與合併過去之LRFD (1986, 1993, 1999)規範之內容加以修改成無因次化公式。受壓構件之分析與設計公式比較LRFD (1999)和AISC (2005, 2010)的勁度折減係數(SRF),比較AISC (2005,2010)與法國規範之有效長度係數(K)的差異性。單角鋼部分使用LRFD(1993)與AISC (2005, 2010)規範的公式做完整的整理與說明，以例題詳細示範闡明單角鋼之分析與設計基本理念與探討、分析。
This study focuses on the analysis and design examples for Tension, Compression and Single Members. elaborated with examples of the correct use of AISC Specification and standardization of the basic spirit of the regulations, believe that through these set of instances, will provide a simpler and engineering practice of design.
We often ignore the tension members which include eyebar and pin-connected members. So, this work is to explore and take into account the relevant formulas and constraints to result in the design steps and obtain the results which are better and economical member sections.
Columns are very important compression members and this study focus on the formulas being given in Specifications LRFD (1999) and AISC (2005, 2010) to provide a more complete analysis of the columns. The stiffness reduction factor is our target to explore in this study. The effective length factor used in French Codes is also investigated for comparison purposes.
Single angles are one concern of the main objectives in this study. The examples are furnished for illustration purpose. The provided examples intend to give the practicing engineers a better procedure for the analysis and design of these angle members. The examples will also enable the design engineers to utilize the single angles members as their selected members in structural system.
