케이블 돔 구조의 자기 평형상태 결정을 위한 새로운 방법

A new method based on the basic principle of closed force polygon for equilibrium system is proposed for the determination of self-equilibrium mode of cable dome structure. The proposed method which is called geometric method has the unique characteristic of visualization of the force mode needed for maintenance of self-equilibrium. The simplicity of the method which involves only drawing close polygon with the aid of suitable CAD software has been illustrated by means of a example.
