POORLY WORDED, ILL-CONCEIVED, AND UNNECESSARY CODE PROVISIONS

摘要

Both the Uniform Building Code (UBC) and the International Building Code (IBC)—to some degree or another— have poorly worded provisions that are unnecessarily complex, are ambiguous, are not justifiable, and/or are overly restrictive. This paper presents just a few of these provisions, the reported justification for these provisions, and suggestions to simplify and improve the codes. Provisions discussed in this paper include the redundancy/reliability factor, the vertical earthquake, minimum base shear and drift limits, and accidental torsion.
