Apr 3, 2025 · A Steel Base Plate Shear Lug is a steel embedment used as a part of an anchorage that transfers shear loads from the structural components to a concrete substrate through different …

A shear lug refers to a steel embedment, which forms part of an anchorage that transfers lateral loads to a concrete foundation. Typically, a welder attaches it to the base plate of an anchor in applications …

This detail complies with the installation requirements of ACI 318 Section 26.7.2, which require proper consolidation of concrete or grout around the shear lugs to be verified using base plate inspection …

It references two types of shear lugs welded to a base plate: “cast-in-place” shear lugs and “post-installed” shear lugs. Cast-in-place shear lugs are cast into the concrete as shown in Figure 1a.

Dec 8, 2020 · Shear lugs are steel elements welded to the underside of base plates to resist shear loads. The design of shear lugs is now included in the ACI 318-19 anchorage provisions, with some …

This spreadsheet is to design shear key or shear lug using ACI 349-06 and AISC 360-10 code. It provides both using or not using anchor reinforcement options for concrete shear breakout check.

Oct 31, 2023 · Friction will resist the shear force until the base plate begins to slide a tiny bit, then the shear lug will take the rest of the shear.

Base plates are usually the interface between two different materials (namely steel and concrete). As a result, although technically straight-forward, a comprehensive design considering all potential failure …

We’re excited to introduce a new feature in the Steel Joints add-on – the ability to define a shear lug within the Base Plate connection.

Shear lug provisions have been introduced into the American Concrete Institute (ACI) publication Building Code Requirements for Structural Concrete (ACI 318-19). This article discusses these …
