The multi-story hotel is situated in seismic zone 2. RFEM allowed modeling and calculating the complex geometry in a realistic way. Using the RF‑DYNAM add-on module, the seismic design could be performed without problems.
Structure and Design
The entire design of the multi-story hotel was carried out in a spatial FEA model in RFEM. In addition to the load cases, self-weight, live load, snow, and wind, equivalent seismic loads have been taken into account.
The building, consisting of several segments, is stiffened by reinforced concrete frames and a staircase core. Due to the structure shape and the necessity to determine the natural frequencies, it was obvious that a spatial calculation would be advantageous.
The hotel has a length of 134 ft, a width of 105 ft, and a height of 51.5 ft. The total mass is approximately 2,314.8 tons.
The structural model consists of 626 nodes, 92 surfaces, and 123 members. The FE mesh has 12,758 nodes and 12,923 finite elements. The calculation time for all load cases (linear analysis) was about 30 seconds.
"The multi-story hotel building is located in seismic zone 2. RFEM made it possible to model and calculate the complex geometry in a realistic way. By using the RF‑DYNAM add‑on module, seismic design could be performed without problems. With a conventional analysis, a realistic calculation of the structure wouldn’t have been possible and would have led to significantly increased construction costs," says Anton Rohmer, the responsible structural engineer.
