Evaluations of the effectiveness of the near‐surface mounted steel materials in strengthening short RC wall‐like columns with openings

Structural Concrete, EarlyView.
Abstract In practice, reinforced concrete (RC) wall‐like columns often have openings to facilitate building services, which creates stress concentrations around the opening, resulting in the weakening of their load‐carrying capacity. This study proposes innovative strengthening methods using near‐surface mounted (NSM) incorporating steel materials to ...

Flexural performance of concrete‐filled steel tubular beams with wood chip aggregate

Structural Concrete, EarlyView.
Abstract This study investigates the flexural performance of concrete‐filled steel tubular (CFST) beams with partial replacement of aggregates by wood chips (0%–25%) through experimental and numerical analysis. This study is novel in that it experimentally and numerically investigates the flexural behavior of CFST beams with partial replacement of ...

Numerically efficient mechanical modeling of reinforced concrete membrane elements with fixed, interlocked cracks

Structural Concrete, EarlyView.
Abstract Compression field approaches such as the Cracked Membrane Model with fixed, interlocked cracks (CMM‐F) are efficient tools for the mechanical modeling of reinforced concrete elements, providing the mechanical model σ=fε$$ \boldsymbol{\upsigma} =f\left(\boldsymbol{\upvarepsilon} \right) $$ required for finite element analyses.

Pre‐failure behavior of continuous post‐tensioned and post‐grouted beam in case of tendon failure

Structural Concrete, EarlyView.
Abstract Grouted tendons are a common solution for long‐span bridge structures. The grout provides bond and corrosion protection for prestressing steel. However, if the grouting is defective, corrosion of the prestressing steel may initiate and eventually lead to tendon failure.

Enhancing durability of steam‐cured precast concrete culverts using SCMs: A comparative study with delithiated beta spodumene

Structural Concrete, EarlyView.
Abstract Steam curing is commonly used to manufacture precast culverts to accelerate early strength development. This study investigates the effect of supplementary cementitious materials (SCMs) on the permeability properties of steam‐cured precast concrete culverts.
