ASCE 7 Wall Zones Explained

ASCE 7-16 has expanded on the definition of component & cladding wind zones from previous ASCE 7 standards. ASCE 7-22 continues with this definition.   Per ASCE 7-22 &16, buildings are composed of 5 different zones, depending on the wind loading they are subjected to. Zones ‘4’ & ‘5’ relate to wall zones & are …

ASCE 7 Least Horizontal Dimension – Minimum Building Width

From ASCE 7 (ASCE 7-22,16, 10 & previous standards):   The “Least Horizontal Dimension” can be taken as the shortest possible distance that can be taken between two parallel lines that fully encompass the building The Least Horizontal Dimension is further demonstrated as follows: Where ‘B’ is the Least Horizontal Dimension.   For further reference, see our …

ASCE 7 Basic Wind Speed

Per definition by ASCE 7-22, ASCE 7-16 & ASCE 7-10, Section 26.2 is defined as:   BASIC WIND SPEED (V): Three-second gust speed at 33ft above the ground in Exposure C (see Exposure Categories) as determined in accordance with ASCE-7  Section 26.5.1. The wind shall be assumed to come from any horizontal direction. The basic …

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 7 Risk Categories Explained

ASCE 7 Risk Category Background Building codes require that buildings be classified by their level of importance in determining the risk taken with safety factors against their failure under critical design loads. Calculations for the structure’s overall stability, flexure, and fatigue are all based on the assumption of a given risk category design level.  ASCE …
