Medical Office Building: Structural Engineering above three parking levels
Two levels of medical office space above 3 levels of partial subterranean parking. The structure has irregular geometry. The front and rear of the building are laid out on varies radii. The sides are non-parallel. Other challenges include high seismic area, non-parallel lateral force resisting systems, in-plane discontinuity of lateral force resisting systems, offset lateral force resisting systems, reentrant corners and diaphragm discontinuity.
BSE performed a dynamic analysis to optimize the lateral force system. The upper structure is special concentric braced frames above special concrete shear walls at the parking levels.
