The incident angle of ground motion is one of the sources of uncertainty in the seismic response of buildings. Moreover, understanding the structural response to the impose ground motion may cause significant changes in the maximum response of buildings. In order to investigate the effect of the spatial distribution of orthogonal components of earthquake strong motion on the structural response...

We are developing a general quadrupedal locomotion controller by using a neural model involving a CPG (Central Pattern Generator) utilizing normal ground reaction force (leg loading) sensory feedback for both rolling motion (posture) and gait (rhythmic motion) control. In this abstract, we report the results of experiments using a quadruped robot “Kotetsu” in order to verify the results of our ...

Sloshing due to ground motion develops large pressure on the walls of water retaining tanks. This paper evaluates the efficacy of padded walls on the reduction of sloshing effects in rectangular water storage tanks subjected to ground motion. An analytical solution based on velocity potential function is provided to obtain the response of  rigid and padded wall tanks in terms of the wave elevat...
