During earthquakes, the most prone to damage or collapse are concrete structures. The structure's behavior during earthquakes depends mainly on its shape, size, and geometry. An attempt is made understand seismic response of Underground Rectangular Water tank structure subjected Nonlinear static loading. To predict building structures severe Pushover analysis has been frequently utilized. It ne...

Abstract The flexible beam theory is widely applied in engineering, due to that many engineering structures can be regarded as beam. For the under large rotation, researches have shown consideration of geometric nonlinearity necessary: deflection will erroneously larger or diverge without nonlinearity. reason lies on dynamic stiffening effect caused by rotation well studied already, however, mo...
