The causes of these high concentration of forces can be introduced by a column, concentrated force, or nodal support. Connecting walls can also cause these concentrated loads at wall ends, corners, and ends of line loads and supports. ![Punching Shear Design in RFEM 6 acc. to ACI 318-19 and CSA A23.3 – Part 1](https://community.dlubal.com/uploads/default/original/2X/4/4f4c123e81c0e0021ccc824a206901d0d1aba9e0.jpeg) * * * 👊 [Punching Shear Design in RFEM 6 acc. to ACI 318-19 and CSA A23.3:19 – Part 2](https://www.dlubal.com/en/support-and-learning/support/knowledge-base/001966) > **Read More** > > This article outlines new enhancements introduced to punching shear design in RFEM 6, expanding on the initial feature set discussed in Part 1.

There's a new article explaining the calculation of moments of inertia for punching shear checks according to ACI and CSA and comparing the method implemented in RFEM 6 with analytical approaches from the literature. 👊 [Polar Moment / Moment of Inertia for Punching Shear Checks in ACI 318 and CSA A23.3](https://www.dlubal.com/en/support-and-learning/support/knowledge-base/002003) > **Read More** > > The article addresses the calculation of moments of inertia for the punching shear check according to ACI and CSA. In RFEM 6, a generally applicable formula from ACI 421.1R-20 was implemented. > > In various technical literatures, in addition to this exact method, there are also analytical calculation formulas depending on the type of punching object. At the end of the article, the different results are compared with each other. ![Polar Moment and Moment of Inertia for Punching Shear Checks in ACI 318 and CSA A23.3](https://community.dlubal.com/uploads/default/original/2X/f/f74c335be254229e3eac5738be14969fd7adefbf.png)
