Sensitivity study on accuracy and relevant parameters in numerical modeling of internal tendon breaks

Structural Concrete, EarlyView.
Abstract This study investigates the numerical modeling of internal tendon breaks in prestressed concrete structures and evaluates the key parameters affecting accuracy. A combined approach is followed, involving global sensitivity analysis via the Elementary Effects Method and subsequent model calibration using experimental data from distributed fiber‐

Rotation capacity of continuous reinforced concrete slab strips revisited

Structural Concrete, EarlyView.
Abstract Rotation capacity is a key characteristic of statically indeterminate reinforced concrete structures, as it (i) enables bending moment redistributions, whether intentionally introduced through optimized reinforcement layouts or arising from unforeseen self‐equilibrated stress states, and (ii) promotes large rotations at failure load, thereby ...

Effective axial strength of laterally strengthened RC pier heads with post‐tensioning method

Structural Concrete, EarlyView.
Abstract This study investigates the structural performance enhancement of reinforced concrete (RC) pier heads laterally strengthened with unbonded post‐tensioning (PT) to accommodate increased design loads following a deck replacement of an existing railway bridge.

Experimental and analytical investigations on the effect of steel fibers on the crack behavior and strength of dapped‐end connections

Structural Concrete, EarlyView.
Abstract Reinforced concrete (RC) dapped‐end connections feature a sharp re‐entrant corner subjected to high stress concentrations, leading to wide cracks under service loads and potential durability issues such as reinforcement corrosion. Effective crack control is therefore essential in the design of new dapped‐end connections. Steel fiber reinforced

Three‐parameter kinematic theory for shear assessment of reinforced concrete short columns

Structural Concrete, EarlyView.
Abstract This work presents a rational kinematics‐based model for assessing the shear capacity of rectangular reinforced concrete short columns. Due to their high stiffness and brittleness, short columns are particularly vulnerable to seismic forces, often exhibiting critical failures.
