In this study, the world's first multi functional fishway is proposed including underground passway, 3D-analysis of slab that load carrying capacity conditions and pectinate and vertical structure by SAP2000 recognized internationally. The structural analysis results are showed comb from than rectangular form of the maximum stress decreased 35.88%, 32.35% reduction in the moment, shear stress decreased 47.36%. Sidewall structural analysis results are showed comb form than the rectangular form of the maximum stress decreased 22.22, 31.88% reduction in the moment, shear stress decreased 43.48%. When we design to alleviate the water pressure of fishway wall, comb shape is more economical design than perpendicular form.
