8文档实用设计说明书现代结构讲究结构与建筑美学相适应，在满足结构功能的同时体现建筑美。这是本作品设计的源泉，制作承受荷载的空间桁架结构模型，具有极强的视觉冲击与震撼，体现了力与美的完美结合。方案构思形象是结构内在品质物化的外在形态，是表现结构内涵和个性的形式和语言系统。为使我们的结构能给人留下特别的印象，考虑从各种技术手段上来表现结构形象。本次以三角形的稳定性为基础再加上多个二元体使之成为几乎不变的稳定体系，以长方体为空间模型的基础创建，再结合美学使结构更加完美。结构选型我们从竞赛的要求与实际情况相协调的角度出发，综合考虑材料的特点，运用桁架的承重方式，以悬线代替拉杆，增加拉杆的强度，减轻模型的自重。其中悬线与压杆的完美结合体现了我们构思新颖和别具一格，不但摆脱了以往桥梁模型设计的外型单调死板，而且给人以强烈的视觉冲击，而同时又巧妙的利用了悬线抗拉的力学原理，设计的宗旨是“结构最简、材料最省、承载力最大。杆件的倾斜为基础构筑桁架。整个看起来给人以异度空间的感觉。文档实用方案图整体图立体图正面图文档实用俯视图侧面图节点详图节点1
