部分的に水に満たされた矩形タンクの地震による影響

抄録

This paper is concerned with the ability of tanks partially filled with water to withstand earthquakes. The interest lies in rectangular water tanks, which have received little attention to date. The analysis is relatively involved and includes the derivation of the equations of motion for the vibration of the whole tank by means of the substructure synthesis method, a stochastic analysis relating the random ground motion caused by earthquakes to the random vibration of the tank, a stochastic characterization of the fluid pressure and computation of the probability of failure of the tank.
