Simple Procedure for Seismic Analysis of Liquid-Storage Tanks

Case studies of two tanks are presented-one broad and one slender tank,both anchored with torsional-beam steel dampers,which dissipate seismic energy by inelastic deformations induced by Seismic Performance Evaluation of Liquid Storage Tanks A simplified approach is presented for the seismic performance assessment of liquid storage tanks.The proposed methodology relies on a nonlinear static analysis,in conjunction with suitable strength ratio-ductility-period relationships,to derive the associated structural demand for the desired range of seismicSeismic Design of Nonbuilding Structures - STRUCTUREAs an example,the struts connecting the transverse moment frames in a pipe rack act as collectors and must be designed for the special seismic load combinations.For nonbuilding structures not similar to buildings,very few elements (e.g.anchor attachment to shells of tanks and vessels) require the use of the overstrength factor in their design.
