扭轉(zhuǎn)的設(shè)計(jì)方法,使設(shè)計(jì)能夠取得較好的經(jīng)濟(jì)效益。我國規(guī)范GB50010-2002首次增加了這方面內(nèi)容。在試驗(yàn)分析的基礎(chǔ)上,對考慮協(xié)調(diào)扭轉(zhuǎn)設(shè)計(jì)的框架邊梁提出了彈性扭矩的估算方法,對扭矩的調(diào)幅系數(shù)的取值作了理論分析,并提出考慮協(xié)調(diào)扭轉(zhuǎn)的具體設(shè)計(jì)和應(yīng)用方法,為我國修訂規(guī)范GB50010-2002有關(guān)條文和設(shè)計(jì)應(yīng)用作參考。

The relative contents are added to the code GB50010-2002 firstly. On the basis of experimental analysis of side beams of frames considered compatibility torsion design, the adjust coefficient of torsion is analyzed theoretically. The design and the application methods considered compatibility torsion are presented. It can be referred to the revise of the code and the application in design.
