【提要】 框架在風荷載及豎向荷載共同作用下，由于框架產(chǎn)生側(cè)移變形從而引起側(cè)移二階效應。為了簡化分析，給出了梁、柱剛度的統(tǒng)一的折減系數(shù)，對彈性階段和極限階段框架側(cè)移二階效應進行了分析和比較，結(jié)果表明在框架設計中應當考慮側(cè)移二階效應。
【關鍵詞】 框架 風荷載 豎向荷載 二階效應 極限階段
Sidesway Secondorder Effect of Frame Under the Action of Wind and Vertical Loads/Tong Shenjia,Tong Yuesheng(Xi'an University of Architecture & Technology,Xi'an 710055,China)Abstract:Under the action of wind and vertical loads,the frame deforms laterally and thus the sidesway secondorder effect is produced.This effect is analysed,and the results show that the sidesway secondorder effect should be considered in design.
Keywords:frame；wind load; vertical load; secondorder effect; limit state
