1スパン1層耐震壁についてフーリエ級数解を利用して求めるせん断型剛性と節点回転断性 : 耐震壁の節点剛性マトリックスに関する実用解 その2

Abstract

This paper is a follow-up of the paper with the same subtitle in the previous Journal of Structural and Construction Engineering (Transactions of AIJ, No. 413, July, 1990). In this paper, a practical calculation method for the stiffness matrix elements, pertaining to the shear type stiffness and the rotational stiffness of the beam-to-column connections assumed to be rigid zone in elastic framed shear walls, is proposed. The shear type stiffness of framed shear walls without floor" slabs can not be evaluated satisfactorily by the I-beam solutions itself. Also, ' the rotational stiffness of the beam-to-column connections can not be evaluated by using I-beam theory. This is because the rotational stiffness of the connections is different from that of horizontal or vertical cross section of the shear wall. Therefore, the practical calculation charts based on the two-dimensional theory of elasticity are proposed in order to obtain the shear type -stiffness and the rotational stiffness of the connections with a high accuracy. These proposed stiffnesses will be adopted in the formulation of a practical nodal stiffness matrix of the framed shear walls together with the flexural and axial stiffnesses which were proposed in the previous paper. This practical nodal stiffness matrix will be useful in analyzing the elastic behaviour of the frame structures stiffened with shear walls by matrix method of structural analysis.
