Ductility improvement of GFRP-RC beams using precast confined concrete block in compression zone

Frontiers of Structural and Civil Engineering doi: 10.1007/s11709-023-0968-8

Abstract: However, owing to the lack of ductility in this material and the quasi-brittle behavior of concrete,FRP-reinforced concrete (FRP-RC) beams, even with flexural failure, do not fail in a ductile manner.Because the limited deformation capacity of FRP-RC beams depends on the ductility of their compressionzones, the present study proposes using a precast confined concrete block (PCCB) in the compression

Abstract:

Over the past few decades, one of the most significant advances in dam construction has been the inventionof the rock-filled concrete (RFC) dam, which is constructed by pouring high-performance selfcompactingconcrete (HSCC) to fill the voids in preplaced large rocks. The innovative use of large rocks in dam construction provides engineers with a material that Prospects for next-generation concrete dams are discussed from the perspectives of environmental
