On the Natural Frequency of Multi-Storey Buildings

A multi-storey building can develop lateral vibrations in the two principal directions and torsional vibration around its vertical shear centre axis. The natural frequency...

Free Vibration of Water Tank Stand When Filled With Water

It is desired to find the eigenfrequencies and eigenvectors (modal parameters) of concrete water tank support when filled with water. This is a case...

Free Vibration of Trusses: A solved Example

Dynamics of structures is a special branch of structural analysis, which deals with the behaviour of structures subjected to dynamic loads (loads that vary...

On Modal Analysis of Rigid Multi-Storey Frames

1.1 Introduction A structure undergoes free vibration when it is brought out of static equilibrium and can then oscillate without any external dynamic excitation. Free...
