In a location classified as wind exposure category C with a design wind speed of 115 mph, what is the minimum uplift force for roof to wall connections?

To determine the minimum uplift force for roof-to-wall connections in an area classified under wind exposure category C with a design wind speed of 115 mph, one must refer to the established standards outlined in building codes, such as the International Building Code (IBC) or the American Society of Civil Engineers (ASCE) standards for wind loads.

The uplift force is calculated taking into account factors such as the design wind speed, the type of building, and its geographical exposure. Wind exposure categories are defined based on the terrain characteristics surrounding a building. Category C typically indicates urban areas or suburban settings with a mix of buildings and some obstructions that increase wind turbulence.

For a design wind speed of 115 mph in this exposure category, the corresponding uplift force is crucial for the structural integrity of roof-to-wall connections. Design load codes specify that these loads need to be adequately addressed to ensure safety and compliance.

In this context, the value of 474 lb has been determined to meet or exceed the requirements based on the calculations outlined in the codes. This value reflects the appropriate safety factors and load considerations put forth by the standards, ensuring that the connections can withstand the forces exerted by wind under the specified conditions. This definitive calculation emphasizes the importance of adhering to code requirements
