Which lateral system is most suitable for repair bays that have large openings?

Rigid frames are particularly suitable for repair bays with large openings due to their ability to efficiently handle both vertical and lateral loads while providing the necessary clearance. This system employs a combination of beams and columns that are connected in such a way that allows for significant spans without needing supporting walls or columns at every interval. This design permits larger open spaces, which is ideal for repair bays that require unobstructed areas for equipment and vehicle access.

Rigid frames distribute lateral forces, such as those from wind or seismic activity, through the frame itself, effectively maintaining structural integrity while accommodating large openings. The capability of rigid frames to maintain strength and stability is crucial in environments where high-load applications and equipment movement are common, making them the preferred choice in this scenario.

In contrast, conventional wall systems typically require more structural walls for support, which limits the size of openings. Shear walls, while effective for lateral stability, also restrict the design flexibility to accommodate large spans. Post and beam structures can achieve large openings but might not provide the same level of overall rigidity and lateral force resistance as rigid frames do, making rigid frames the optimal choice for the requirements of a repair bay with large openings.
