Abstract This paper presents the buckling response and vibration characteristic of cylindrical steel liquid storage tanks filled with water when subjected to strong earthquake excitations. Finite element analysis (FEA) is performed by using ABAQUS software. The geometrically perfect different R/t H/R ratios are considered for modal linear seismic analysis. modeling method, appropriate type, nec...

In this paper, results are presented on asymmetric sloshing in partially filled circular cylinders subjected to horizontal, periodic forcing, as well as geyser formation and the subsequent axi-symmetric sloshing that is caused by a sudden change in Bond number. Asymmetric sloshing is controlled by three parameters that are the liquid depth parameter, the frequency offset (depending on forcing f...

tuned liquid dampers (tld) are among passive control devices that have been used to suppress the vibration of structures in recent years. these structures must be adequately presentable as an equivalent single degree of freedom system with long fundamental period. the tld, located at the top floors of the structure, can dissipate the external input energy into the system through the sloshing ef...
