| Abstract |
The design of high strength underground septic tank stiffened by steel pipe is presented and the ultimate behavior is investigated according to the full scale experiments for three types of specimens. The limitation of the current design specification are pointed out and the general design procedure of private sewage treatment facility are newly developed considering thickness of FRP shell, types of steel pipe stiffer and diaphragm wall. The direct tensile and bending test for FRP material of septic tank were performed. The increase effect of ultimate strength due to the circular steel pipe are investigated by the full scale field test and compared with the results by the finite element analysis. |
