Design Guide for Twisting Moments in Slabs

447R-2018 发布历史

This design guide applies to slabs of both uniform and nonuniform thicknesses@ including drop caps and drop panels@ except where noted in the text. This guide does not apply to waffle slabs@ or the beams of beam-and-slab floor systems. Chapters 3 through 6 address slabs and walls in which the response is determined purely by bending. Chapter 7 addresses shells for which the response is determined by bending and membrane action. Chapter 6 and the theory sections of this guide are applicable to walls. Chapter 7 and the theory sections of this guide are applicable to shells@ with the caveat that equations presented in Chapter 3 are not valid for curved shells.
