DOI: 10.1007/s12205-020-5145-1
Abstract: Frequently, construction requirements demand to provide service pipelines passing laterally within slab thickness near the slab-column connections of flat slabs. The flat slabs including such conducted pipelines are expected to undergo a significant reduction in… read more here.

DOI: 10.1016/j.engstruct.2018.11.073
Abstract: Abstract One of the main collapse modes of reinforced concrete flat slabs is the punching of the slab-column connection in which the load is applied in a reduced area. Such condition generates significant shear stresses… read more here.

DOI: 10.1016/j.engstruct.2020.110483
Abstract: Abstract One of the major disadvantages of conventional fibre-reinforced polymer (FRP) strengthening techniques is the premature debonding of the FRP, leading to an underutilization of the materials. The externally bonded reinforcement on grooves (EBROG) method,… read more here.

DOI: 10.1016/j.engstruct.2020.111745
Abstract: Abstract The growing use of fibre reinforced concrete (FRC) for structural purposes has led several guidelines to include design-oriented models that allow the partial (and even total) substitution of the steel reinforcing bars. Among those,… read more here.
