[关键词]  空腹桁架 连续代入法 设计建议

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
