Mass component is one of the big three component for a dynamic system. It is contributed by dead load and certain portion of live load exerted on structure.
Here, we look into the development of lumped mass model by converting real condition to idealized condition through a series of assumptions. Then, we use an example to show the calculation of mass component.
The following introduces the mass component in a dynamic system. Watch the video above for full details.
Idealization of construction material as isotropic material
Idealization of floor element as rigid diaphragm
Calculation of mas component in a structure
Idealization of structure using m, k and c components
