抄録

The problem of inappropriate time-history waveforms due to gaps between wall and fluid particles in the boundary conditions of SPH method was solved by modeling the wall particles shifted by the smoothing length. Based on the verified method, a fluid analysis was performed where cubic buildings were aligned. As a result, the continuity of pilotis space in orthogonal direction to mainstream causes the concentration of the hydraulic force on the wall of the building located downstream direction of the piloti-type buildings. And the continuity of pilotis space in mainstream direction also keeps the level of water pressure over a distance.
