鋼構造梁柱接頭設計之整合系統

Abstract

如何讓鋼構造之梁柱接頭充份發揮應有的強度並達到安全，經濟及施工簡 易之目標在整個結構設計過程中為重要之一環。而國內目前在鋼構造樓房 設計上較常用的柱形式為 H型柱及箱型柱，梁為 H 型鋼梁。設計方法上 有美國鋼構造協會(American In- stitute of Steel Construction，簡 稱AISC)所出版的容許應力設計法(Allowable Stress Design，ASD) 及1986年出版的極限設計法(Load and Resistance Factor Design， LRFD )。所以本文之目的即在以ISDS為分析軟體，針對由規範及文獻所發 表的梁柱接頭中，在符合足夠的強度，延展性與經濟性上，利用C 語言將 分析結果與梁柱之細部設計整合。依不同設計方法，柱型式，與材料強度 中，將結果以圖形表示出供參考。 The beam-to-column connections are very important for steel structures to achieve its full stiffness, ductility , economic and safety in the whole design procedure. At present, most connections types are H-column to H- beam or Box-column to H -beam, and the design provisions with AISC-ASD or AISC-LRFD. The purpose of the paper is to estabilish an automatic detal design for connections of various types based on AISC -ASD and AISC-LRFD. Examples are used to illustrate the efficiency of this program in design. The results can be seen from the screen and out- put to a plotter.
