Secondary moments in prestressed beams with FEA

Posted on 09/01/2023 by dougaj4

Secondary (or hyperstatic) bending moments occur in prestressed beams that are continuous over internal supports, or have other redundant support conditions. Any eccentric prestress force will cause a beam to deflect, and if these deflections are restrained at internal supports, … Continue reading →
