A Period Formula For Reinforced-Concrete Building

철근콘크리트 건물의 고유주기 산정식

Until now, various period formulas Pre proposed, but those of have a little difficult procedure and variation according to structural system. This paper presents an analysis of the uncoupled vibration of symmetric in RC structures. A generalized approximate method is developed using the Southwell-Dunkerley approximation and characteristics of structural deformation. The results of the proposed method for the example structure show good agreement with those of the Midas Genw4.2.2.
