Abstract

Determination of the maximum shear capacity of reinforced concrete (RC) beams and slabs has been a challenging task for over 100 years. Recently, the shear crack propagation theory (SCPT) was developed as a unified mechanics-based solution to determine the ultimate capacity and to explain the phenomenon of one-way shear in RC members without shear reinforcement. The proposed theory is not limited to steel-RC members and can be applied to members with nonmetallic reinforcement accounting for their material parameters and constitutive relationships. Further, the SCPT does not focus only on the ultimate state but also on the behavior during the entire loading process up to failure. In this paper, the application of the SCPT is extended to RC members with longitudinal fiber-reinforced polymer (FRP) reinforcement without stirrups for the first time. A parametric study is first presented to explore the effect of FRP bar properties on shear behavior and shear transfer mechanisms in RC beams. Subsequently, the experimental results of 44 beam tests reported in the literature are used for validation. The results showed that the SCPT provided accurate estimates of the shear strength of FRP-RC beams that compared favorably with those from current design codes. [ABSTRACT FROM AUTHOR]

Abstract

Summary: Background: To prevent complications of paediatric ulcerative colitis (UC), it is critical to understand their predictors. The Paediatric Inflammatory Bowel Disease Ahead (PIBD Ahead) program identified the relevant outcomes and their potential predictors. However, external validation of these results in larger cohorts is required. Aims: The aim of this study is to investigate these outcomes and their predictors. Methods: We included 743 patients aged under 18 years with UC from the multicentre German‐Austrian CEDATA‐GPGE registry. We performed Cox regressions, Kaplan–Meier estimator, and receiver operating characteristics curve analyses to analyse predictors of poor outcomes. Results: Older age at diagnosis was associated with relapse, hospitalisation, the use of immunomodulators, use of biologics, and therapy escalation. Higher disease activity, as in acute severe colitis in the first 3 months, was significantly associated with further acute severe colitis and the need for biologics. Upper gastrointestinal tract involvement was a risk factor for the need of intravenous corticosteroids and biologics. A faecal calprotectin of >685 μg/g was associated with a higher risk of subsequent acute severe colitis with a sensitivity of 79.0% and a specificity of 59.1%. A lower haematocrit at diagnosis was predictive of the use of biologics. Colectomy was rare. Conclusions: This study validates predictors of poor outcomes in paediatric patients with UC. Our results might help physicians to anticipate poor outcomes and initiate appropriate treatment strategies at an early stage. [ABSTRACT FROM AUTHOR]

Abstract

Despite of intensive research on concrete fatigue, the transfer of fatigue characteristics determined at the material level to the structural level remains a challenging issue. In this paper, the propagation of fatigue‐induced damage through the concrete structure is analyzed using a microplane fatigue model for concrete recently developed by the authors. To this end, our recent experimental study in which the fatigue propagation was monitored at the structural level represented by prestressed concrete beams is used to derive a general interpretation of the stress redistribution process using of the developed model. The numerical studies show that the developed microplane fatigue model provides a powerful computational tool for in‐depth analysis of the correspondence between the fatigue behavior at the material and structural scales in a wide range of load configurations. In addition, the thermodynamically based constitutive model allows for the quantification of the energy dissipation during the process, revealing the possibility of deriving material‐specific energetic characteristics that can further help to make the predictions of fatigue life more accurate. Highlights: Structural experiments validate the constitutive fatigue hypothesis.Damage‐induced energy dissipation is an objective value for fatigue characterization.Insights into the fatigue life extension of concrete at the structural level are provided.Structural stress redistribution induces variable load amplitudes at local level.
