In case of the realization of scissors-type expandable structure, one of the most important problems is concerned with the rational method of expanding and rocking. This paper describes a new type of expandable arch structure which consists of three-hinged arch scissors and zigzag flexible cable through pulley with them. The changing form of this structure is controlled by only winding up or back instrument like a winch, and a special stable truss arch without chords is always gained during the winding process because the cable is effective against tension force under gravity load. A trial test of a 5-m span steel arch was carried out by this basic idea about changing form structure, and we got the hopefull light of this method.
