Seismic Structural Engineering

Seismic structural engineering designs buildings to resist earthquake forces — lateral load-resisting systems, shear walls, moment frames, diaphragms, and connections designed to ASCE 7 and local seismic requirements. Apex Grid provides seismic engineering for new construction across all seismic design categories and seismic retrofit engineering for existing buildings.
