(東南大學土木系 南京 210096)[提要] 推導了考慮水平和垂直位移時空腹桁架連續(xù)代入法的計算公式。同時,結合本文的算例和分析,對空腹桁架的設計提出了一些合理建議。
[關鍵詞] 空腹桁架 連續(xù)代入法 設計建議The calculation formulas of successive approximations method of the Vierendeel truss are derived by considering horizontal and vertical displacement. At last, based on some computation examples and further analysis, some design proposals of Vierendeel truss are presented.
Keywords: Vierendeel truss; successive approximations method; design proposal
