Analysis and Design of Base Insulators Applied to the Helipad of the Hospital Structure

Resumo

In catastrophic situations, rescue cannot be carried out via ground ambulances, which makes helicopters
a very common solution to locate and transport patients to hospitals. However, due to the small areas in urban
centers, hospitals choose to build landing areas on the rooftop, optimizing the space available. The main problem
of this proposal is the transmissibility of vibration caused by the helicopter landing and takeoff, affecting
employees, patients and equipment inside. In general, construction in hospitals, especially when they are still in
operation, require simple, fast and effective solutions. For this, metallic structures and passive insulation are widely
used in elevated hospital heliports. For passive isolation, some indicators are necessary for an efficient reduction,
such as, applied loading, type of material and degree of transmissibility. For this study, analytical and numerical
calculations are necessary, each of which is extremely important to assess whether the vibrations transmitted to
the building will be negligible or whether it is necessary to add something for reduction.
