| Abstract: |
Present study is to investigate mechanical behavior of concrete filled steel tube members (CFT) with thinner steel plate than specified in considering practical application to either new or strengthening existing members. Asymmetric four-point static loading test have been conducted for beam type specimens with a square cross section. Test parameters were shear-span ratios of 1.0 to 2.0 and steel tube width-thickness ratios of 65 to 200. Three dimensional nonlinear finite element analyses have been also conducted for test results. Flexural mode failure has been observed for shear span ratio of 2 and shear mode failure for that of 1 in good agreement with analytical results respectively. |
