Final Answer:
The minimum thickness requirement for a masonry bearing wall exceeding one story is typically dictated by structural considerations and building codes. Therefore, the answer depends on the specific structural and design requirements of the project.
Step-by-step explanation:
The minimum thickness of a masonry bearing wall for a multi-story structure is not universally standardized but is governed by structural engineering principles and local building codes. The thickness is influenced by factors such as the height of the building, the type and quality of the masonry material, and the expected loads the wall will bear.
Structural engineers analyze these factors to determine the appropriate thickness that ensures the wall's stability and ability to support the vertical loads imposed on it. Building codes provide guidelines to ensure safety and compliance with structural standards, allowing for variations based on specific project requirements.
