Conventional CLT panel construction methods have many complex joining methods, creating complications in both structural design and on-site construction. In this study, a CLT unit with a simplified joining method using large diameter screws was proposed, and tensile and shear element tests of the screws and full-scale shear tests of the unit walls were conducted. As a result, it was confirmed that high bearing capacity could be achieved even with the simplified joining method. In addition, two types of usage were demonstrated: strength type and toughness type, depending on the screw joining method.
