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.

Prediction of prestressing losses for long term operation of nuclear reactor buildings
EPJ Web of Conferences, 2011 Prestressed concrete is used in nuclear reactor buildings to guarantee containment and structural integrity in case of an accident. Monitoring and operating experience over 40 years has shown that prestressing losses can be much greater than the design ...

Low frequency acoustic properties of bilayer membrane acoustic metamaterial with magnetic oscillator
Theoretical and Applied Mechanics Letters, 2017 A bilayer membrane acoustic metamaterial was proposed to overcome the influence of the mass law on traditional acoustic materials and obtain a lightweight thin-layer structure that can effectively isolate low frequency noise. The finite element analysis (

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.

Structural Concrete, EarlyView.Abstract Steel fiber reinforced concrete (SFRC) enhances the flexural capacity of flat slabs and, due to its effectiveness in statically redundant bi‐dimensional elements, represents a viable alternative to conventional reinforcement. Although numerous studies have investigated the flexural behavior of SFRC slabs with and without bonded reinforcement ...

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‐

FINITE ELEMENT ANALYSIS OF POST-TENSIONED CONCRETE BOX GIRDERS
Journal of Engineering, 2007 The behavior of prestressed concrete box-girder bridges has been studied under short term loading. The 20-noded isoparametric three-dimensional brick elements have been used to model the concrete in the box-girder with its two cantilever flanges.
