The Seismic Performance of Reinforced Sustainable Concrete Low-Rise Structures

Abstract

The utilization of sustainable concrete in producing reinforced concrete structures subjected to seismic actions is one of the leading research topics of recent years. With the technical exhibition that this concrete may be used in conventional reinforced concrete structures, a significant threshold for this sustainable material is accomplished. In the scope of this study, the seismic behavior of five different reinforced concrete structures under seismic actions, which are considered to be produced from sustainable concrete and conventional concrete, was investigated in detail. The geometrical, cross-section, and longitudinal section dimensions of these reinforced concrete structures are convenient for the equivalent seismic load method to use effectively. Furthermore, the Turkish Building Seismic Code limits were considered for the numerical simulation of reinforced concrete structures. Based on this detailed seismic simulation, the equivalent seismic load method may be used in earthquake simulation of reinforced concrete structures incorporating sustainable concrete. Furthermore, the numerical simulation results obtained from the sustainable concrete structures were extensively compared with the conventional concrete structures results. It may be concluded from these results that there are negligible differences between the seismic performance indicators of reinforced sustainable concrete structures and conventional concrete structures.

Sustainable precast composite deep beams including concrete with partial replacement (50%) of recycled coarse aggregate

“…[12] investigated experimentally the impact of steel bers on the shear behavior of concrete deep beams using 100% recycled concrete aggregate (RCA). SARIBAŞ [13] used RCA in four different ratios: 25%, 50%, 75%, and 100%. It was found that deep beams with 25% and 50% RCA behaved similarly to conventional deep beams.…”
