A 8.5 meter simply supported reinforced concrete beam on
parallel rectangular column, where the column width is 300 mm is shown in Figure carries a
uniformly distributed variable action of 10 kN/m and permanent action of 9 kN/m (including
self-weight of beam). The clear cover of beam for class XC-1 is 25 mm, diameter of main and
shear reinforcement are 20 mm and 8 mm respectively. The characteristic material strengths
are fck = 30 N/mm² and fyk = 500 N/mm². Apply variable Strut Inclination Method to design
the shear reinforcement (links) for the beam.

Implement a cross-sectional analysis based on a layered discretisation of the cross- section as required at the following. 1) Develop the implementation of an analysis to estimate the nonlinear response of the composite steel-concrete section, of the reinforced concrete section and of the steel section shown in following slides (using material nonlinear models provided in the support files). Provide the details of the numerical implementation with clear explanations of all steps. Hint: the implementation can be done in Excel. 2) Discuss how the 3 cross-sections (shown in the next slides) compare to each other in terms of embodied carbon under the condition that the cross-sections possess the same nominal moment capacity (i.e. the peak moment achieved in the moment-curvature diagram).
