A few studies have been reported on methods to estimate initial stiffness of reinforced concrete beams with spandrel walls and structural slit at both ends. Therefore, structural design conducted by engineers is based on their own experiences in the calculation. The purpose of this paper is to estimate the initial stiffness of reinforced concrete beams with spandrel walls and structural slit at both ends. It was reported that four specimens were tested under static alternating cyclic loads to investigate initial stiffness of reinforced concrete beams with spandrel walls and structural slit at both ends1)2). In this paper, it was observed that the axial strains developed close to both ends of the specimens were similar to S-shape distributions in elastic range. Therefore, an evaluation method of initial stiffness of reinforced concrete beams with spandrel walls and structural slit at both ends based on S-shape strains was proposed.
