Effect of Increase in Thickness of Gypsum Board Composite Panel on Improvement in Out-of-plane Drywall Stiffness

석고보드 복합패널의 후판화에 따른 면외방향 내력 증대 효과

The demand for drywall is increasing as the structural type of apartment building is changing to a rigid frame structure. At present, the thickness of the gypsum board used for drywall is mostly 9.5mm and is required to be changed to 12.5mm to improve the performance of the wall. A structural safety test has been conducted in accordance with KS F 2613 to verify the effect of changing the thickness of the gypsum board to 12.5mm in terms of improvement as to stiffness. As a result of the test, the stiffness of the drywall has increased by about 19.6% and the impact resistance by about 30.4%.
