Strengthening of Slab-Column Connections with CFRP Strips / Wzmacnianie Połaczen Płyta-Słup Za Pomoca Tasm CFRP

[摘要] The paper describes experimental research of slab-column connections examined on specimen designed as a part of reinforced concrete structure with flat slabs. The aim of the research was to verify the efficiency of slab reinforcement concept against punching shear by increasing slab’s mechanical reinforcement ratio by applying additional external reinforcement in the form of carbon fiber reinforced polymer (CFRP) strips. The capacity enhancement in comparison to unstrengthened slab obtained 36%.
