Experimental Study on the Static Characteristics of String Crescent Structure Made From Reusable Parts

Abstract

I proposed Crescent System and String Crescent Structure (SCS). Crescent System secures a reuse function, and SCS is the structure that stabilized Crescent System. I made the models of SCS of the cantilever and did an experiment and analysis. This purpose is to clarify the influence of Crescent part shape and the prestress on structural behavior of SCS. I show consideration based on the result below.1) The stress transmission mechanism between Crescent Parts was estimated, and this mechanism was demonstrated by the experiment and the analysis.2) I analyzed a stress, rigidly and the geometric element, and I was able to estimate the proper value of Minor arc angle.3) Crescent part shape influences the rigidity of SCS. A mechanical role of arms is only the reduction of deformation. 4)A mechanical role of the prestress of the strings is prevention of deformation by slide, and improvement of structural performance of SCS.5) The experimental value accorded with the analysis value in "Load-displacement"and "Load-tension of the string".
