Abstract
A detailed investigation of the RC elements subject to horizontal forces and the effect of the rotational stiffness were conducted in this paper by using numerical methods. Since the early ‘1960 this technique be-come used by engineers but only in the last decade, due to the development of the computing machines the method was used on a large scale. The paper deals with a technique. The paper deals with a summary of recent techniques in manipulating the stiffness matrix of the constitutive materials in efficiently solving problems related to connection between horizontal forces and rotational stiffness. The paper pro-pose some practical methods deducted from theoretical formulation of the stiffness matrix and propose new formulation of the stiffness matrix for this completely applicable to the new technique. At last the paper analyses a three level RC structure using a FEM based computer soft with the method proposed and delivers the results.
