Time history analysis for floor vibration.

Structural dynamics is a type of structural analysis which covers the behavior of a structure subjected to dynamic actions having high acceleration loading. It is vital that this serviceability condition be investigated and considered during the design. Dynamic loads include people wind waves traffic earthquakes and blasts any structure can be subjected to dynamic loading. Modal time history analysis is well suited for the modeling and analysis of human induced vibrations which result from such impacts as pedestrian footfalls.

Please note that these parameters are not intended to be realistic. In the time history analysis of the floor under single walking load the loading program of moving point loading was adopted in accordance with the test. Dynamic analysis can be used to find dynamic displacements time history and modal analysis. It analyzes the floor systems with different boundary conditions beam spans and damping ratios.
