SRC梁柱設計與ETABS程式之應用

Abstract

本研究旨在探討鋼骨鋼筋混凝土梁柱構材(SRC Beam-Column)之強度與設計強度之相 關問題，並初步嘗試結合ETABS程式以發展一可用於SRC構造設計之電腦程式。 本研究 對於SRC構材梁柱強度係採用「剛度分配」之概念與「強度疊加」之方法來計算其強度， 並與AIJ-SRC 規範(1987)、AISC-LRFD規範(1993)及ACI 318-95規範(1995)之設計結果互 相比較。此外，本研究收集了國內外21篇論文中之123支SRC構材實驗資料來比較本建議法 與各國規範對SRC構材強度之預測結果，研究結果顯示本建議法可以得到合理之設計結果 。此外，由於目前工程界常用的ETABS軟體並未具備SRC構造之分析與設計功能，因此本研 究乃嘗試採用本文所提出的SRC梁柱設計法並結合ETABS軟體，初步研擬一可用於SRC構造 之結構分析與設計之電腦程式，以供工程界參考。 最後，期望本研究之結果對國內SR C構造設計品質之提昇有正面之意義。 The object of this research is to investigate the related problem of the ul timate strength and the design strength of steel reinforced concrete (SRC) mem ber. Besides, the research is attend to development a computer program combine d with ETABS for SRC structural design. The design method based on the "Rela tive Rigidity Ratio" concept and the"Strength Superposition" concept is sugges ted to calculate the beam-column strength of the SRC member. Then, the design strength of the SRC member obtained by the proposed methods are compared with the results calculated by those formulae suggested by AIJ-SRC code (1987), AIS C-LRFD specification (1993) and. ACI-318 Building Code(1995). Besides, 123 tes t data from 21 papersare collected by this research to compare with the streng th predicted by theproposed method, AIJ-SRC code, AISC-LRFD specification and ACI-318 Code. Besides, a computer program developed by the proposed method i s attended to combine with ETABS software. Finally, a design example (22 stori es building)is provided to prove the usability of the program.
