Accounting for the vibrations of the classic and supercars
The next challenge the project faced was vibration. The ground floor showroom above the workshop had 22m clear spans and therefore the vibration of the floors had to be carefully controlled. The resonant frequency of the V8 engines is at 4.5Hz which is close to walking pace, and the natural frequency of the floors themselves. The response of the floor was assessed using the software provided by Kloeckner Metals UK and the beams strengthened to ensure that the vibration experienced by the building’s occupants will be within the prescribed limits.
During the project, the building height was reduced in height by 1m and the use of virtual modelling allowed us to reduce the structural zones to match, including the redesign of the floor and roof structures on a tight timetable to allow the showroom to be opened in time for Christmas 2017.
The final challenge was the design of the roof above the main entrance to the building. The architect’s vision was for an 8m long cantilevered roof projecting from the building line over the terrace to provide a continuous eaves line around the perimeter of the building. The contractor erecting the frame expressed doubts about the capacity of the steelwork to cantilever that distance and so a series of load tests were undertaken to demonstrate that the performance of the building was consistent with the prediction of our computer models.
The design won the LABC West of England Regional Award for Best Large Commercial Building in 2017 and went on to be Finalist in the LABC Grand Final Awards the same year.
