Abstract

Large reductions in embodied carbon can be achieved through the optimisation of concrete structures. Such structures tend to vary in depth along their length, creating new challenges for shear design. To address this challenge, nineteen tests on non-prismatic steel reinforced concrete beams designed using three different approaches were undertaken at the University of Bath. The results show that the assumptions of some design codes can result in unconservative shear design for non-prismatic sections.
