Résumé:
This work aims to understand and study how structures behave when being subjected to
vibrating equipments, these vibrations last for a long period of time (maybe decades) and this is
what is called a steady-state vibration according to dynamics literature. The steady-state analysis
underwent several checks such as the amplitude, velocity, acceleration, and most importantly the
check of resonance phenomenon in accordance with the codes ACI 351 "Report on foundations for
dynamic equipment" and ISO 1940 "Balance quality requirement of rigid rotors». Comparative
analysis also was done between Global and discretized models to simplify and reduce analyzing
time and found that using a discretized model is more efficient in matter of time consumption, and
also, checked the importance of locations of the machine on the found results which turned out to
be very important and always lead to reduce the cost of the support of the machines, All these
analyses were done using the software SAP2000
