摘要:图解静力学由彼此交互的力图解和形图解组成，通过力图解生成形图解对方案阶段的结构形态推敲有十分积极的作用。本文首先根据认知心理学的理论，分析得出力图解原型应具备适宜的抽象水平，即中等抽象水平；其次，从结构内力方向、支座数量、构件姿态、荷载分布状态与荷载分解方式构建了二维力图解原型谱系；最后，确定参数数量、梳理参数间关系、编写程序生成多个结构形态。本文的研究目的旨在提升力图解操作的交互水平，使设计师在构思方案时更容易操作。

Abstract: Graphic statics consists of interactive force diagram and form diagram. Form diagram generated by force diagram plays a very positive role in structural form design in protocol stage. Firstly, this paper explores that the prototype of force diagram should have an appropriate abstract level, which is moderately abstract concept representation according to the theory of cognitive psychology. Secondly, it constructs its 2D lineage from 5 aspects, e.g. the direction of structural internal force, the number of supports, the component form, the load distribution and the load decomposition. At last, this paper determines the number of parameters and figures out the relations between parameters and writes a program to generate many structural forms. This paper aims at the improvement of interaction level, which makes it easier to operate force diagram when architects conceive projects.
