WebLoad application from the residential floors above can be the most troublesome part of the design process. Bearing walls can be irregularly spaced, staggered with plan offsets and feature concentrated loads from posts and hold-downs. Design is iterative – walls move, framing orientation changes, and wall openings are modified. WebFeb 3, 2024 · 1607.9.1.2Heavy live loads.

WebDating back to the 1940s, AASHTO had used three basic live load models to approximate the vehicular live loads that would be experienced by a bridge: the H or HS design trucks, the design tandem, and the design lane loading. The HS design truck, or standard truck, is a three-axle truck intended to model a highway semitrailer. WebWhere uniform roof live loads are reduced to less than 20 psf (0.96 kN/m 2) in accordance with Section 1607.13.2.1 and are applied to the design of structural members arranged so as to create continuity, the reduced roof live load shall be applied to adjacent spans or to alternate spans, whichever produces the most unfavorable load effect.
