Experimental Study on Vertical Load Bearing Capacity of Wall Panel with Wood-frame Covered by Bamboo Strips

In order to study the vertical load bearing capacity of wall panel with wood-framed covered by orthogonal oblique placement bamboo strips, three types of composite wall panels specimens, i.e. double-sided bamboo strips, bamboo strips-gypsum boards, and laminate-gypsum boards, were tested to investigate the failure forms, load-deformation curves, and ultimate bearing capacities. The results showed that in the early stage of wall failure, the surface bamboo strips were bent, and the middle parts of the laminate board and the gypsum board were bent. With the load increasing, some nails connecting the laminate board and the gypsum board to the wood frame were pulled out, and some of the bamboo strips bent further. The wall panel damaged by the buckling of vertical keels in the end. The orthogonal placement bamboo strips improved the axial load carrying capacity of the specimen. The ductility of wall panel with bamboo strips was better than that of the laminate board and gypsum board covered wall panel specimen. This indicates that the wall panel with wood-frame covered by bamboo strips has potential engineering application value, and it is beneficial for subsequent theoretical analysis.
