Dual potential capacity model for short and deep reinforced concrete members containing steel fibers

Structural Concrete, EarlyView.
Abstract This study presents an analytical model for estimating the shear strength of short and deep steel fiber‐reinforced concrete (SFRC) members with a shear span‐to‐depth ratio less than 2.5. To this end, a dual potential capacity model (DPCM) is developed based on the demand‐capacity approach for evaluating the shear strength of SFRC beams that ...

Nonlinear analysis of flat post‐tensioned concrete slab–edge column connections

Structural Concrete, EarlyView.
Abstract This study presents nonlinear finite element analyses to investigate the punching shear behavior of unbonded post‐tensioned concrete flat slabs at slab‐edge column connections. A parametric analysis was conducted to evaluate the influence of four critical parameters on the punching shear resistance: the distribution of prestressing tendons ...

Experimental study of the size effect on punching shear of steel fiber reinforced concrete slabs

Structural Concrete, EarlyView.
Abstract As the behavior and design of steel fiber reinforced concrete slabs subjected to punching still remain an area of concern, the present work aims to provide a further contribution to the knowledge on punching behavior of slabs without transverse reinforcement.

Numerical analysis of the effects of corrosion on the punching shear capacity of reinforced concrete flat slabs with openings

Structural Concrete, EarlyView.
Abstract The reinforcement corrosion is one of the main degradation mechanisms in reinforced concrete structures. Its effects can harm structural elements by reducing mechanical capacity, mainly due to diminished reinforcement properties and expansive reactions within the concrete.

Evaluation of prestress losses in concrete beams using destructive and non‐destructive methods

Structural Concrete, EarlyView.
Abstract Over the past few decades, prestressing techniques have become essential in the construction of key structures, infrastructure, and bridges. The serviceability and safety of prestressed concrete (PC) elements are closely tied to the effectiveness of the prestressing process.
