Response of Elevated Water Tanks Subjected to Lateral Loads

Kaul Matresh, Nallasivan K.

Civil and Environmental Engineering Reports

2022

Vol. 32, no. 2

118--131

During previous earthquakes around the world, it was discovered that elevated water tanks were severely damaged or collapsed. As a result, structural engineers are concerned about the analysis of these structures to gain a better understanding of the effects of seismic loads on elevated water tanks. In the current study, E-Tabs software, which is based on finite elements, is used to model various shapes of elevated water tanks along with various staging patterns. The higher stiffness of the supports in cross staging tanks makes them better than normal staging tanks, according to the results of the analysis. Furthermore, circular tanks perform better than other tank shapes when subjected to seismic loads. The study looks at water tanks subjected to static seismic loads. More research is needed to determine the analysis results for the dynamic seismic loads applied to the structure. All the analysis results are derived from the software's tank analysis results.

This study evaluates the movement of a frame built on soft soil under seismic excitation taking into account soil-structure interaction. First, the study was evaluated using the finite element method, then, by using a substructure method which modelled the soil using springs and dampers in a linear and nonlinear study. Rheological models were determined using impedance functions, calculated using a numerical program CONAN. These dynamic impedances are shown in the displacement vector of a three-degrees-of-freedom frame, which was calculated on the basis of lateral forces distributed over the structure height using the equivalent static method. In this regard, two different calculation norms were chosen; RPA2003 and UBC97. Finally, a parametric study was carried out, based on the effects of soil densification and the foundation geometry on the response of the RC frame.
