(寧波大學(xué)建筑工程與環(huán)境學(xué)院 315 211)[提要] 在半剛性連接平面鋼結(jié)構(gòu)基本假定的基礎(chǔ)上,從經(jīng)典的單元模型(剛度方程)出發(fā),用嚴(yán)格的數(shù)學(xué)推導(dǎo)建立了桿件兩端可具有任意連接剛度的平面鋼結(jié)構(gòu)的一般彈性分析計算模型。當(dāng)模型中的連接約束參數(shù)取特殊值時,可退化為經(jīng)典的計算模型(完全剛性連接和完全鉸接),使模型具有一般性。通過算例對計算模型進行了分析比較。
[關(guān)鍵詞] 半剛性連接 平面桿系結(jié)構(gòu) 普遍模型On the basis of the fundamental assumptions suggested for the planar steel structures with semi-rigid connections, the generalized elastic computational model of the planar steel structures which the arbitary connection stiffness can be set at the two ends of the elements is put forward through strict mathematical analysis. As the parameters associated with the connections considered in the model are taken as special values,the computational model can be easily degenerated into the two idealizations: fully rigid and pinned. Finally, the numerical results are put forward.
Keywords: semi-rigid connections; planar structures; generalized model
