Verifying the Shear Load Capacity of Simultaneously Horizontally and Vertically Reinforced Masonry Walls by the V Rd – N Ed Interaction Diagram

This paper describes principles of verifying load capacity of masonry walls subjected to horizontal and vertical loading in accordance with EN 1996 - 1 - 1:2010 and the draft version of Eurocode 6 (prEN 1996 - 1 - 1:2017), As in the V method (where only vertical reinforcement is present) or in the H method (where only horizontal reinforcement is present), the VH method analyses simultaneously the vertical and horizontal reinforcement. The analysis included cases a, b, and c, which differed in the distribution of normal stresses at the wall edges determining the form of equations for ultimate limit states (ULS). Necessary equations for determining load capacity of a section against vertical load N Ed are presented. There are also representative V Rd – N Ed interaction diagrams.
