STRUCTURE Articles

The past decade has witnessed an increasing adoption of mass timber buildings in North America. These innovative structures primarily feature large, engineered wood products, such as glued-laminated timber (glulam) and cross-laminated timber (CLT). Recognized for their sustainability, these materials align […]

Fall Protection Anchorage Design Insights Heidi Lopez-Hidalgo, P.E. 2022-10-01 6:45:00 The design of structures utilized to support fall protection systems (FPS) for workers at height is a topic that is often researched and questioned but is not a straightforward process. […]

Robust Anchorages to Concrete Structures Christoph Mahrenholtz, Ph.D.2022-09-01 7:05:00 Anchor Channels in Industrial Structures, Bridges, and Tunnels Anchor channels with channel bolts enable the robust anchorage of components to reinforced concrete structures. State-of-the-art systems comprised of anchor channels and channel […]

Anchor Bolt Provisions in the Masonry Code Richard M. Bennett, Ph.D., P.E.2022-05-01 7:05:00 The phrase “the devil is in the details” applies to anchor bolt design in masonry structures. The anchorage of masonry members is essential both for load transfer […]

Undercut Anchors for Structural Applications Philipp Mahrenholtz, Ph.D. 2022-04-01 7:10:00 Ductility is Critical Undercut anchors are the ultimate post-installed anchor category as their load transfer mechanism is bearing, similar to that of headed studs cast into concrete. Tensile loads are […]

Integrating Shear Lug Design with Anchoring-To-Concrete Provisions Richard T. Morgan, P.E. Erratum Figure 2(b) and Figure 3(b) in the article incorrectly show the bearing area (Aef,sl) as a T-shaped configuration. This configuration is only relevant when stiffeners are used. Since the shear lug […]

Large Anchor Grout Pockets for Foundations Silky Wong, Ph.D., S.E., P.E., CEng MICE A Review of Design Considerations Grout pockets are man-made holes in concrete structures (pre-installed before concrete placement or drilled after concrete placement) to allow the installation of […]

Federal Changes for Post-Installed Adhesive Anchors T. J. Bland, P.E. April 2020 The wheels of change turn slowly when it comes to government regulations. For federal highway infrastructure, some of the regulations for new construction have not been modified for […]

Beyond Bond Strength of Adhesive Anchors Alexis A. Clark, P.E. Testing, Design, and Specification A variety of factors influence an engineer’s decision to use  cast-in anchors or post-installed anchors including working principles, installation, and the impact on project timeline and […]

Analysis of Anchoring Attachments Using Finite Element Modeling Richard T. Morgan, P.E. Anchoring-to-concrete provisions in the American Concrete Institute’s Building Code Requirements for Structural Concrete (ACI 318) are used to calculate anchor design strengths that consider possible anchor failure modes.
