Errata are intended to correct editorial issues with the standard, but not to make technical change. Reasons are never posted for errata. Ordinary concrete cantilever columns have never been permitted in Seismic Design Category C, D, E or F for building structures. The section 12.5. limitation on axial ...

Dollin Good catch. In earlier editions of ASCE 7 (16, 10, etc) the rule was that if the weight of the nonstructural component exceeded 25% of the combined weight of the structure and component, then explicit modeling of the component with the structure was required. ASCE 7-22 modified this requirement ...

No. However, 12.2.5.1a does apply to pre-engineered metal buildings, permitting their use in higher SDCs ------------------------------ Ronald Hamburger, SE Consulting Principal Simpson Gumpertz & Heger ------------------------------

Many, but not all, cantilever column structures are also inverted pendulum structures. What is special about an inverted pendulum structure is that the mass at the top of the structure has considerable rotational mass moment of intertia that is resisted only by the column (or columns). The elevated water ...

That section of ASCE 7 is intended to permit the use of ordinary steel moment frames in typical low-rise residential construction, commonly composed of repetitively framed wood stud or cold formed steel stud walls. It is not uncommon in such construction to use moment frames as the lateral support along ...
