This is similar to the concrete filled steel tube (CFT), because the wood occupies the inner space of steel tube mainly, and WGFT has advantages of its weight against to CFT. Also, WGFT is made of cement grout which is easy to get and cast than the high flow concrete casted in CFT. WGFT was developed to use for seismic retrofitting brace for reinforced concrete structure. In the previous tests, the authors have tested short columns and six long columns under concentric compression. The main test parameters are shapes of the steel tube and diameter of the inner wood. The axial stiffness and strength deceased according to the increases of the sectional area of the wood. After the investigation for the behavior of the short columns of WGFT, centrally loading test was conducted for the long columns. These specimens failed in buckling and attained the maximum strength. These results showed that the axial load carrying capacities were estimated by the summation of buckling strength of each component. The paper shows that the possibility of actual use of WGFT for seismic retrofit., 長崎大学大学院工学研究科研究報告, 50(95), pp.13-19; 2020}, pages = {13--19}, title = {鋼管に木とグラウトを充填した合成構造柱の中心圧縮性状に関する基礎的研究(その3)}, volume = {50}, year = {2020} }
