Fundamental studies on design methods of circular reinforced concrete columns; Tekkin concrete enkeichu no sekkeiho ni kansuru kisoteki kenkyu

Abstract

For the purpose of establishing design methods considering effects of shapes of the cross section of the circular reinforced concrete columns, made are elucidation of fundamental mechanical characteristics and proposal of various calculated equations of strength. From the experiment on flexural fracture of the RC circular column with circular spiral transverse reinforcing bar, it is found that the more the number of repeated loading, the smaller the toughness, and that even when receiving high axial force, the RC circular column with a full amount of transverse reinforcing bar does not break in the large deformation plastic zone where the angle of rotation of member is up to 1/30, if a total of 100 repeated loads are laid. In the ultimate strength design method, derived is the necessary calculated equation of accurate ultimate flexural strength of the cross section of the RC circular column without using the existing method. It is indicated that this calculated equation favorably infers the maximum flexural strength in obtained the serial analysis, and also that conformity to experimental values is equal to those obtained in the serial analysis. Further, in the experiment on unidirectional monotonic lateral loading under the fixed axial force and the experiment on  More>>
