Title: Strut-and-Tie Models versus sectional Shear Design - A Discussion Contribution
Author(s): Karl-Heinz Reineck
Publication: Special Publication
Appears on pages(s): 1-18
Abstract:The sectional shear design in B-regions of beams according to the empirically derived rules given in Ch. 11 of ACI 318-08 leads unavoidably to discrepancies when separately designing the adjacent D-regions by using a strut-and-tie model according to Appendix A of ACI 318-08. A “full member design” with the truss is the only model providing a consistent transition from B- to D-regions, in which the angle of the inclined struts in the webs of beams can be derived from the rules given in Ch. 11 of ACI 318-08.
Furthermore two important D-regions in beams are dealt with, which are the D-region where a point load is applied near the support and the D-region where a beam is indirectly supported by another beam.
Finally a list of references is given for further guidance in application of strut-and-tie models or could serve as basis for writing such a document.
