摘要：
Finishing materials installed at the building surface closest to the living space of people often fall down and harm the life, body or property. However, few reports are available on the material properties of finishing materials that are necessary to assess the degree of risk. Here we show the compressive properties of the representative finishing materials such as gypsum boards. In this study, a series of compressive tests at various strain rate from 10-5 to 103 s-1 were conducted. The results confirmed the strain rate dependence of the compressive strength and identified the constants for Cowper-Symonds constitutive equation. © 2019 Architectural Institute of Japan.
