（浙江杭蕭鋼構(gòu)股份有限公司 杭州 310003）[提要] 針對我國現(xiàn)行鋼結(jié)構(gòu)規(guī)范中的不足，探討Z型連續(xù)搭接檁條的結(jié)構(gòu)性能：荷載分布、搭接嵌套松動、內(nèi)力計算、側(cè)向穩(wěn)定以及構(gòu)件極限承載力等問題。此外，還討論了帶隅撐檁條的計算特點和雙檁條的構(gòu)造優(yōu)點，提出了適合實際工程的算法，使冷彎薄壁型鋼檁條設(shè)計更為經(jīng)濟(jì)合理。方法和結(jié)論可供設(shè)計人員參考。
[關(guān)鍵詞] Z型檁條 連續(xù)搭接 蒙皮效應(yīng) 拉條The structure behaviors of the continue Zee purlins with lap connection, work loose of lap connection, mechanic analysis, lateral buckling and ultimate resistance capacity etc., has been studied. Besides, the mechanic analysis of the purlins with flange brace and the superiority of double-purlins are also discussed. The analysis method for practical projects is suggested which results in designing purlins reasonably and economically.The suggestion may be as a reference to steel structure design.
Keywords: Zee purlins; lap connection; diaphragm effect; tension bar
