Shear design of HSC beams with combination of links and horizontal web steel [PDF]

open access: yes, 2005
The existing recommendations in Eurocode 2 and the British Code of Practice for the shear design of beams are derived from research conducted essentially on normal-strength concrete (NSC) with cube strengths up to 50 MPa, and it was found that the shear ...

Simplified Effective Compressive Strengths of Columns with Intervening Floor Slabs

open access: yesInternational Journal of Concrete Structures and Materials, 2020
The current design codes discuss the effective compressive strengths of columns, which reflect a decrease in load transfer performance that can occur when columns and slabs have different concrete compressive strengths. The effective compressive strength
