Relationship Between Economy And
Sustainability For A Multi-storey Reinforced
Concrete Frame Structure

Abstract
Reinforced concrete structures are not generally known as sustainable ones due
to the excessive use of limited limestone resources and due to the possible
negative impact on the environment of using large quantities of energy for
producing the rebar and the structural concrete. Unfortunately, understanding the
shortcomings of these structures is not equivalent to finding alternative structural
solutions with much lower environmental impact, which could respond to the
same design theme. If a multi-storey, multi-bay reinforced concrete frame
building is given, choice of proper concrete and reinforcing steel quality can lead
to substantial savings, but how can the savings be related to the environmental
impacts? In order to study the relationship between the economy and the
environmental impact for the same given frame structure the structural design
has been carried out for two versions of material use, where the first version is
based on concrete class C16/20 and reinforcing steel class PC52 while the
second version uses concrete class C30/37 and reinforcing steel class S500. The
next step is the comparison of the structural solutions by means of the material
lists and the realization costs of the structures, but the final conclusions could not
be deducted without taking into account the estimated required energy for
realizing both structures. Based on the calculated structure the paper concludes
by providing the relationship between the economy and the sustainability of the
used structural materials.
Keywords: sustainability of concrete structures, economy and sustainability,
