Abstract: A systematic study is made of the effects of base uplifting on the seismic response of cylindrical liquid-storage tanks that are supported directly on flexible soil foundations. First, a detailed investigation is made of ...

Abstract: The seismic performance of liquid-storage steel tanks can be improved by anchoring them to their foundations with energy-dissipating devices rather than with conventional anchors. Case studies of two tanks are presented—one ...

Abstract: Ground motions recorded during earthquakes are often used to assess the seismic performance of structures affected by those ground motions. However, it is necessary to first establish the return period of the recorded ...

Abstract: Motivated by a need to understand the effects of earthquake-induced pounding at thermal expansion joints of concrete bridges, the first part of this paper deals with collinear impact between concrete rods of the same cross ...

Abstract: In the conventional seismic analysis of a system, the input motion is defined either by a probabilistic response spectrum or by ground-motion histories whose spectra “match” the probabilistic response spectrum. In both ...

Abstract: A new method for seismic base isolation of ground-supported vertical cylindrical liquid-storage tanks is proposed in which the base plate is supported on a soil bed, and the tank wall is supported on a ring of vertically ...

Abstract: Earthquake-induced uplifting/settlement at the base of liquid-storage tanks causes yielding in the bottom plate. Limited amount of yielding is a source of deformability and damping in tanks, but excessive yielding during ...
