に対しては抵抗できなかった。However, the composite wall of the continuous wall and the outer wall using the stud bolt as described above has the following problems. It is necessary to perform a base treatment on the stud bolt welding portion of the core material. In-situ welding of stud bolts is dangerous due to work at heights, and also degrades quality, and requires an overall construction period and cost. The number of stud bolts is determined by the shear and tensile forces acting between the outer wall and the core. Groundwater that permeates the continuous wall and reaches the outer wall stays widely on the surface. The core material sufficiently resisted out-of-plane forces but failed to resist in-plane forces.
