Special Issue Information

Dear Colleagues,

It is my pleasure to announce this Special Issue of Materials, entitled “Analysis and Performance of Reinforced Concrete Structures.” which will focus on analysis and performance of reinforced concrete structures. As we all know, reinforced concrete structures, built for meeting the various functional requirements in engineering construction, have wide use in civil engineering. More recently, the performance of reinforced concrete structures and that of ultra-high-performance concrete (UHPC) in extreme condition have undergone intensive investigation and aroused great interest among researchers. Studies have tended to target application in harsh environments, which has significantly advanced our understanding of reinforced concrete structures.

This Special Issue aims to provide a platform for the analysis and discussion of the performance of reinforced concrete structures used in all the areas of civil engineering. This includes not only building engineering, but also transport infrastructure and special engineering.

Abstract

Strain-hardening cementitious composites (SHCC) are an attractive construction material with obvious advantages of large strain capacity and high strength, as well as excellent workability and easy processing using conventional equipment. Moreover, SHCC can be designed with varied mix proportions in order to satisfy various requirements and expectations to overcome the shortages of existing construction materials. However, the behavior of SHCC in the structural application is varied from that of SHCC material, which is reviewed and presented in this paper, focusing on the flexural and shear behavior of the SHCC member and the SHCC layer used for strengthening reinforced concrete (RC). The reviewed results demonstrate that both the zero-span tensile behavior of the stress concentration and the uniaxial tensile behavior of the bending effect can influence the crack propagation patterns of multiple fine cracks in the SHCC strengthening layer, in which the crack distribution within the SHCC layer is limited near the existing crack in the RC substrate member in the zero-span tensile behavior. Moreover, the crack propagation patterns of the SHCC strengthening layer are changed with varied layer thicknesses, and the SHCC strengthening layer, even with a small thickness, can significantly increase the shear load carrying capacity of the shear strengthened RC member. This work provides the foundations for promoting SHCC material in the structural application of repairing or retrofitting concrete structures. Full article
