可撓筋違架構による制震構造の研究(その2) : 可撓筋違架構の解析とその特性

Abstract

Shear walls in reinforced concreate structures and bracings in steel frame structures has been considered to more effective elements for earthquake and wind force. However, these lateral resistant elements offen possese too high rigidity to alleviate powerful earthquake force against framed structure, and moreover in spite of a great amount of capacity carrying over loads, these structures are apt to become rather more brittle. So we mainly analytically have developed a reasonable earthquake resistant elements, namely so-colled flexible curved bracings, of which especially steel structure is formed. It is considered that framed structure having bracings like this may be given more moderate and realistic rigidity and ductility. The framed structures having curved bracings is analized by means of the theoretical methods which is shown in part 1. It is shown that the framed structure having curved bracings be able to more moderate and realistic rigidity and ductility by adjust angle of curved bracing.
