摘 要 本研究旨在探
討鋼骨鋼筋混凝土(SRC)構材極限強度設計上之相關問題。研究中首先 以
「直接強度疊加」之概念探討SRC構材之彎矩強度、剪力強度與軸力強度
,並分別提出 新的設計方法,然後再與AIJ-SRC 規範(1987)、AISC-
LRFD(1993)規範相互比較,研究結 果顯示本建議法可以得到合理之結果
。此外,本研究對SRC梁柱構材設計方法提出三組建 議設計方法,其中兩
組建議法係結合「剛度分配」之理念, 並對混凝土之非線性行為加 以考
量,以期得到合理之設計結果;第三組建議法則以「直接強度疊加」之概
念進行SRC 梁柱之設計, 研究中將以三組建議法所得之結果與國外主要
的規範作比較,以驗證本建 議法之適用性。 最後,本研究並發展一套結
合ETABS程式之SRC構造設計檢核程式,針對一棟十層樓之SRC 構架進行結
構分析與強度檢核,以驗證本研究建議方法之可行性。 關鍵詞﹕鋼骨鋼
筋混凝土,直接強度疊加法,彎矩強度,剪力強度,軸向抗壓強度,
剛度分配法,梁柱設計。
Abstract The
object of this research is to investigate the related
requirements of ultimate strength design (USD) of steel
reinforced concrete(SRC) members.This study is firstly based on
the "Direct Strength Superposition" concept todetermine the
flexural strength、shear strength and axial strength of the
SRCmembers with proposed design methods. Then the nominal and
design strength ofthe SRC member obtained by the proposed
methods are compared with the resultscalculated by those
formulae suggested by AISC-LRFD specification (1993) andAIJ-
SRC code (1987). It has been shown that the results of the
proposedmethods are reasonable. Besides, the new design
approaches are suggested forSRC beam-column design. Tow of
the approaches are based on the "RelativeRigidity
Distribution" concept. To obtain satisfactory results of the
SRCbeam-columns design, inelastic behavior of concrete portion
is considered inthis study. And the third proposed method is
based on the "Direct StrengthSuperposition" concept to design
SRC beam-columns. Then a comparison amongthe SRC beam-column
strength predicted by the AISC-LRFD specification, theAIJ-SRC
code and the proposed method to prove the practicability
of theproposed approach. Finally, a computer program
based on the proposed methods is developedfor SRC structural
design. It is found that the results obtained form the
proposed method are satisfactory. Key words : Steel Reinforced
Concrete (SRC), Dire ct Strength Superposition
