Failed the Ductility Verification? How to Pick a Higher εmu, the Maximum Compressive Strain

The addition of boundary elements to MASS Version 4 (as well as CSA S304-14) means that failing a ductility verification is not the end of the line   Boundary elements allow for the confinement of reinforcement in compression. Not only does this unlock more flexural capacity as steel in compression Read more…
