When the section of a beam is prismatic, the Equivalent Stiffness Ratio(E.S.R.) of the beam are 3/4, 1/2 and 3/2 depending on to conditions of hinge end, symmetric deformation, antisymmetric deformation respectively. The aim of this study is to find out haunched the E.S.R. changes when the beam is haunched.
The results of this study are follows.
1. The values of E.S.R. of hinged case in the same as the multiplication of the values of the symmetric deformation and the antisymmetric deformation cases when the beam is the symmetric haunched.
2. The values of E.S.R. of end A and end B of the unsymmetric haunched beam are equal.
3. When the values of E.S.R. between horizontal haunched case and inclined haunched case are
compared, generally the horizontal case's absolute difference from the 0.5 is greater from that of
