Abstract: Several types of multilayer vierendeel truss transfer structure are introduced. The behaviors of them are comparatively analyzed. And the influence of section size of chord, layout of web-member and section size of web-member are presented. Based on the analysis ofvierendeel truss, the design advices are given. Then combined with an actual engineering; the paper presents the design principle and constructional details to vierendeel truss.
Keywords: multilayer vierendeel truss; transfer structure; design principle; constructional details
