Abstract

System supports are widely used in concrete construction due to the convenience and structural safety at the point of both installation and dismantling. However, there were frequent collapses in the construction sites due to the absence of both structural review and brace installations. Therefore, this paper examines the importance of braces in the system supports. In order to examine the importance of the brace, four types of braces were considered: 100% braces, 50% braces, 25% braces, and without braces. The maximum displacement of the 100% braced model was 0.97 mm, the 50% braced model was 1.13 mm, the 25% braced model was 1.16 mm and the non-braced model was 24.3 mm, respectively. Compared to the model with the without-braces, the model with 100% of the braces installed has a displacement of 4.0%, the model with 50% of the braces showed a displacement of 4.7%, and the model with 25% of the braces appeared to be a displacement of 4.8%. That is, the installation of the braces is effective in reducing the maximum displacement of the system supports and is effective in reducing the maximum displacement with only small number of braces installed.
