Based on the manufacturer's BIM model, the Matrix engineers created a 3D finite element analysis model to calculate the various stresses throughout the entire structure. In addition, it was necessary to ensure that the deflection of the stairs would be kept to a minimum so that no damage would occur to the terrazzo flooring.
The stair stringers (which also function as fall protection) as well as the steps are made of steel sheets t = 0.98 in. with a steel quality S275. The height of the stringers is approx. 4.59 ft. The Steel Design and Stress-Strain Analysis add-ons were used for the design in RFEM.
