[20] carried out a similar study for RC moment frames, while Medeiros
and Kripka [21] proposed the minimization of monetary and environmental
costs of rectangular RC column sections. The work of
Fernandez-Ceniceros et al. [22] presents a decision criterion based
on the embodied CO2 and the overall cost of one-way floor slabs.
This paper addresses the sustainability challenge by incorporating
the CO2 emission objective in the search for the optimum design of
precast–prestressed concrete U-beam road bridges.
