通过优化混凝土结构可以大幅减少隐含碳。这种结构倾向于沿其长度沿着变化深度，从而为剪切设计带来新的挑战。为了应对这一挑战，在巴斯大学进行了19项试验，对采用三种不同方法设计的非棱柱形钢筋混凝土梁进行了试验。结果表明，某些设计规范的假定会导致变截面截面抗剪设计的不保守。
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.
