Strip loading in reinforced concrete: Mechanical modeling and experimental validation

Structural Concrete, EarlyView.
Abstract Strip loading of reinforced concrete is a common problem in engineering practice. The concrete compressive strength at the load introduction can be several times higher than the uniaxial concrete compressive strength, which can be attributed to geometrical and passive confining stresses caused by load dispersion and reinforcement, respectively.

Effect of stirrup spacing on strengthening beams with insufficient shear capacity using innovative mechanical steel stitches

Structural Concrete, EarlyView.
Abstract This study investigates experimentally and analytically the effect of stirrup spacing variation on the behavior of reinforced beams in the 45°‐inclined innovative mechanical steel stitches (MSSs) application for the strengthening of reinforced concrete beams with insufficient shear capacity.

A new smooth failure criterion for concrete inspired by Lubliner's condition

Structural Concrete, EarlyView.
Abstract A new failure criterion with 10 parameters is proposed, based on Lubliner's idea of joining two Drucker–Prager cones. The novelty lies in the way of introducing deviatoric shape variation: through two Podgórski's functions. This feature allows for improving plane stress cross‐section's compatibility with experimental data.

Numerical analysis of debonding behavior of FRP sheets bonded to concrete focusing on mortar skin

Structural Concrete, EarlyView.
Abstract This paper proposes a novel simple method for finite element analysis (FEA) to simulate the debonding behavior of fiber‐reinforced polymer (FRP) sheets bonded to concrete. This study focuses on the mortar skin of the concrete surface layer, which fails during FRP sheet debonding.

Framework for X‐ray mirror surface shape fitting

Journal of Synchrotron Radiation, EarlyView.
The closed‐form expressions for elliptic cylinders, hyperbolic cylinders, ellipsoids, hyperboloids, and diaboloids used for X‐ray mirror surface shapes are summarized. Additionally, a four‐layer framework to fit the measured surface shape data in slope or height for convenient X‐ray mirror surface characterization is proposed.For accurate ...
