Consideration of Drop Caps and Drop Panels for Punching Shear Design

ADAPT-Builder v22 now includes the ability to model a Drop Cap and a Drop Panel at the same support. The Punching Shear check considers both Drop Caps and Drop Panels when creating critical sections for the Two-Way Shear Design. Whether modeling a Drop Cap, a Drop Panel, or a Drop Cap within a Drop...

Precompression in Two-Way Post-Tensioned Slabs

Introduction In the design of two-way post-tensioned slabs, whether it be by use of unbonded or bonded tendons, precompression or “average minimum precompression,” is a critical serviceability requirement in ACI318. It is used to serve as a means for selecting a prestressing force and/or quantity...
