Consider the cross-sections illustrated in the next slides. 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).
The discussion should include at least 2 sets of the sections (each set
contains one composite section, one reinforced concrete section and
one steel section with same nominal moment capacities) and should
consider the effects of different material and geometric properties.
Make sure to support your discussion with quantitative results that can
be presented in tables/figures.
3) Comment as to why the number of sections, material and geometric
properties considered in your answer to Question Part 2 are sufficient
to provide the requested overall trend on how these sections compare
to each other in terms embodied carbon for equivalent ultimate
responses.

Notes:
1) Assume the y axis to be pointing downwards.
2) Equations of material properties and other support information
are/will be provided in separate file/s.
