Slabs strengthened for punching shear with post-installed steel and CFRP connectors
Revista IBRACON de Estruturas e Materiais, 2019 Structural accidents due to punching shear failures have been reported in flat slab buildings. Design recommendations presented by codes can lead to entirely different punching shear resistance estimates for similar situations.

The shear behavior of CFRP Strengthened RC beams
Magazine of Civil Engineering, 2020 The primary objective of this paper is to study the effectiveness of using externally applied CFRP composites as a method of shear strengthening. The parameters investigated in this study included CFRP amount and distribution (i.e., sheet versus strips), bonded surface (i.e., web sheet versus U-wrap), and fiber orientation (i.e., 90° fiber direction ...
