リユース材で構成された張弦クレセント構造の力学性状に関する研究

摘要

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 mechanic^ 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".%リユースシステムの一つ，クレセントシステムを提案し，クレセントシステムの安定化を目的に弦材を付加したSCSの構造挙動の検討を行った結果，次のような知見が得られた。(1)せん断伝達メカニズムに関して，C部品間の離間の進行を抑える為に，圧縮側の弦材にわずかな張力が発生する事を，実験お よび解析により裏付ける事ができた。
