Then the area required to support that load is calculated based on strength of material. A third section presents stability criteria for members subject to buckling and for members subject to special conditions.
Dead load and wind load analysis is performed in staad pro. Tension members strength of materials tension physics. One measure of the effectiveness of a member such as an angle connected by one leg is the distance, x, measured from the plane of the connection to the centroid of the area of the whole section. The single angle and double angle sections fig 2a are used in light roof trusses as in industrial buildings.
