The boundary frame restricts the vertical deformation caused by the rotation of HPFRCC response control element. Therefore, the restraint axial force works for the response control element, and hysteresis characteristic of the response control element is greatly different from the case in which the axial force does not work. This paper proposes the prediction method that simply estimates load-deformation relationship of HPFRCC response control element. Axial displacement, horizontal displacement, restraint axial force and shear force are calculated in any compression edge strain. Therefore, it is possible that shear force-horizontal displacement relationship and axial force-horizontal displacement relationship are quantified in making compression edge strain to be a parameter. And, effectiveness of the proposed estimation method was confirmed through the comparison between results of the static lateral loading test and analytical value.
