Accounting for Architectural Demands and Construction Phase in Structural Design
The structural design of a three-story building in Palmela, near Lisbon, Portugal, is analyzed. Because of architectural constraints, the main facade of the first floor was designed in a setback of the second floor, which created a 13.0 m (42.6 ft) span between supports. To comply with deflection requirements a Vierendeel girder was projected between the second and third floor slabs. Taking advantage of the reduced size of the structure and therefore low computation demand, two nonlinear analyses were conducted. To account for the effect of creep in the construction phase, a physically nonlinear analysis was performed. Furthermore, the second-order effect on the vertical elements was accounted for through a geometrically nonlinear analysis. The nonlinear analyses allowed for a more slender and cost-efficient design when compared with values obtained from the traditional abacus to account for viscoelasticity.
