Remaining strength of frame material in wooden wall panels of buildings at Syowa Station, Antarctica
The remaining strength of frame material in wooden wall panels of buildings being used now at Syowa Station in Antarctica was measured by wood screw pulling out tests. An initial value of pulling strength of wood screws was assumed referring to the test report by Hirai et al. (Nankyoku Shiryo, 46, 4...
