Numerical Simulation on Dynamic Behavior of Slab–Column Connections Subjected to Blast Loads [PDF]
Applied Sciences, 2021 Although many studies on the blast-resistant performance of structures have focused mainly on single members such as beams and columns, there is little research on the behavior of joints that are subjected to blast loads.

Design of biaxially loaded external slab column connections
Engineering Structures, 2021 Abstract The paper investigates the influence of biaxial loading on punching resistance at square and elongated edge columns of flat slabs which is virtually neglected in the literature. In the absence of experimental data, the influence of biaxial loading is determined using nonlinear finite element analysis (NLFEA) with 3D solid elements.

Experimental and Numerical Investigations of Punching Shear Strengthening of Slab-Circular Column Connection Incorporating UHPC and Galvanized Threaded Steel Bolts [PDF]
International Journal of Concrete Structures and MaterialsPunching shear failure poses a critical risk in flat slab–column structures, potentially leading to catastrophic collapses. Retrofitting methods typically involve flexural or shear strengthening.

Punching shear analysis of slab‐column connections [PDF]
Engineering Computations, 2013 Purpose – The paper aims to present an experimental testing program regarding reinforced concrete slabs, with and without shear reinforcement, submitted to punching under both symmetric and eccentric loading. Comparisons between numerical simulations and experimental behaviour results are carried on.

Post punching shear pattern and progressive collapse of flat slab building [PDF]
Revista IBRACON de Estruturas e Materiais, 2023 The possibility of the occurrence of a second punching shear failure and of a Progressive Collapse after a punching shear failure had occurred in one flat slab column connection is investigated in two building structures, using Eberick and SAP2000 ...

Strengthening of bi-axially loaded RC slab-column connection using steel plates and stiffeners
Przegląd Naukowy Inżynieria i Kształtowanie Środowiska, 2021 This paper presented a strengthening technique for enhancement reinforced concrete (RC) slab-column connection behavior using steel plates and steel stiffeners. A bi-axial load was applied with an eccentricity of 150 mm in both x and z directions.
