Abstract:
The mechanical properties of cellulose fiber gypsum board have been investigated in bending, tension and compression. It shows a quasi-plastic behavior in the ultimate range and a strain softening behavior in the post-peak regime. Wall panels made of a timber frame and fiber gypsum board sheathing can be used as a lightweight structure in residential buildings. A cyclic test on such an element showed good deformability with high shear resistance which suggests the use of such panels in seismically loaded structures. For full understanding of the deformation potential, more tests are necessary.
