How Were RISA Products Utilized?
With the unique soil challenges and the need to keep the structural system exposed, engineers at Advanced Structural Design, Inc. relied on the full RISA Suite to efficiently deliver a robust and coordinated design. RISAFloor and RISA-3D were utilized to model the three-story concrete frame, design the two-way elevated slabs and supporting beams, and verify the performance of the concrete shear walls that provide the building’s main lateral-force-resisting system. Integration with RISAFoundation was also utilized to design the concrete footing elements bearing on vibro stone columns, helping to address the poor soil conditions while keeping foundation sizes compatible with the superstructure layout. Throughout the project, the ability to pass models and loads seamlessly between RISAFloor, RISA-3D and RISAFoundation allowed the team to maintain uniform beam and form sizes, respond quickly to architectural changes, and adjust reinforcement where needed without sacrificing constructability or schedule.
