Can Firestop Systems Be Used to Address Gaps Around Fire Door and Fire Window Assemblies?

Ryan Kolodetsky and Matthew Winston
Reading time: < 10 minutes
Firestop systems cannot be used to address gaps around fire door assemblies or fire window assemblies. Gaps around fire door and fire window frames should instead be resolved through the applicable opening protective listing, manufacturer’s installation instructions, NFPA 80 requirements, or direct guidance from the door/window assembly manufacturer.

How Can ACI 318-19 Provisions be used for Extension Design of Post-Installed Reinforcing Bar?

Richard T. Morgan, P.E.
Reading time: < 10 minutes
Post-installed reinforcing bars evaluated per AC308 Table 3.8 can be designed using the ACI 318-19 development and lap splice provisions applicable to cast-in reinforcing bars. Development length (ℓd) and tension lap splice length (ℓst) are calculated using Chapter 25 requirements.

What is the Difference Between Mechanical vs. Adhesive Post-Installed Anchors?

Cara Green
Reading time: < 10 minutes
Mechanical anchors transfer load by friction, bearing, or mechanical interlock and can be loaded immediately after installation. Adhesive anchors transfer load through bond between the anchor, adhesive, and base material, offering greater flexibility in embedment depth, diameter selection, and edge distance requirements and cannot be immediately loaded.
