Abstract

Recently, modular building system has been applied mid to high-rise buildings for residential. G/W (Glass-Wool) Panel are often used for the members of modular system. The aim of this paper is to validate the structural performance of modular exterior stone joints using G/W panels and screw connections and the propose for the detailed design of the connection for exterior stone panels using self-drilling screw. The specimens consisted of G/W panel to exterior stone connection with angle connector, lipped plate and self-drilling screws, and the pull-out and shear performance of the modular exterior stone connections is verified using UTM. The major test parameters of pull-out test were the number of self-drilling screws, the diameter of self-drilling screws, and the support conditions. The major test parameters of shear test were the number of self-drilling screws and installed G/W panel. The test results showed that the pull-out strength and shear strength of the proposed details are 4.81 kN and 31.08 kN, respectively, and the pull-out and shear performance of the detailed joints for the stone load (one sheet, 39 kg) are excellent. In addtion, in order to evaluate the structural performance of the self-drilling screw in the modular stone exterior joint details, the design strength of the self-drilling screw calculated through the formula presented in "KDS 41 30 30: 2022" should be reviewed.
