Anchoring reinforcement according ACI

Concrete

Detail 3D

ACI (USA)

IDEA StatiCa is a tool for solving complex 3D tasks and is fully verified for anchoring in concrete. This solution allows you to perform designs without oversimplifications and provides checks based on the Ultimate Limit State (ULS).

Together with IDEA StatiCa Connection for anchorage verification, Detail provides a comprehensive solution for everyone dealing with steel-to-concrete connections. In Connection, you can evaluate anchors in a plain concrete block, while in Detail, it is possible to assess the impact of additional reinforcement.

This workflow is already proven by users in real practice who use Eurocode, for whom it has been possible to solve 3D tasks since version 24.1. See the release note: Detail out of beta.

IDEA StatiCa Detail

IDEA StatiCa Detail is now fully integrated with the ACI standard, now including 3D in Detail. The environment supports both imperial and metric units, and assessments are conducted in full compliance with the ACI standard.

Models can be created either from scratch or using predefined templates directly within the application.

For non-conforming anchorage evaluations based on ACI formulas for plain concrete, the model can be exported from IDEA StatiCa Connection. The export includes loads, anchor parameters, and basic dimensions. Only the reinforcement needs to be added. More about the import can be found in the article: Import of Anchoring from Connection to Detail.

The results are presented in accordance with ACI standards, incorporating proper nomenclature, strength reduction factors, and relevant design provisions. Described in more detail in the Theoretical Background in chapter dedicated to ACI.

Known limitations for 3D in Detail

Since Detail is just a tool and cannot replace engineering judgment, a safe understanding of its functions, benefits, and limitations is necessary. Read the limitations that must be taken into account:

The solution is suitable only for reinforced concrete.
Verified only for anchoring.
The application provides ULS checks.
Only one concrete block is supported in Detail.
In Detail, the anchors are only checked for tensile strength. It is necessary to use Connection for shear and interaction checks.
Only models anchored via the base plate and only Direct contact can be imported to Detail (from Connection).
Imported loads and user-input loads cannot be combined within one model.
