ASCE 7 Main Wind Force vs. Components & Cladding Explained (MWFRS vs. C&C)

ASCE 7 separates wind loading into three types: Main Wind Force Resisting System (MWFRS), Components and Cladding (C&C), and Other Structures and Building Appurtenances. MWFRS is defined as “(a)n assemblage of structural elements to provide support and stability for the overall structure.” Typically, members that receive loading from two surfaces are designed to resist MWFRS …

ASCE Wind Speed Risk Category To Use with Signs & Building Components On-Off Buildings

ASCE 7-10, ASCE 7-16 Wind Pressure Information and Wind Pressure Calculators In terms of determining the risk category to a building component mounted to a building, the component ‘inherits’ the design properties of the structure. So a sign attached to a risk category II structure would be risk category II. If the sign is freestanding …
