Moment redistribution in continuous FRP reinforced concrete beams [PDF]

Construction and Building Materials, 2013
Abstract The main purpose of this paper is to assess moment redistribution in continuous concrete beams reinforced with fibre reinforced polymer (FRP) bars. A numerical technique based on equilibrium of forces and full compatibility of strains has been developed to evaluate the moment–curvature relationships and moment capacities of FRP and steel ...

Local Buckling Influence on the Moment Redistribution Coefficient for Composite Continuous Beams of Bridges

The Baltic Journal of Road and Bridge Engineering, 2010
The present paper is concerned with the elastic design optimisation of continuous composite beams. This optimisation is based on the analysis of the beam in the inelastic range including the concrete creep and shrinkage, the tension stiffening and ...

Tunable cationic distribution and structure-related magnetic and optical properties by Cr3+ substitution for Zn2+ in nanocrystalline Ni-Zn ferrites

Results in Physics, 2021
We report a microwave-combustion synthesis and structure-related physical properties of Ni0.4Zn0.6−xCrxFe2O4 (0.0 ≤ x ≤ 0.6) nanocrystals in a study of effects by substitution among cations with different oxidation states, Cr3+ for Zn2+.

Quantifying moment redistribution in FRP-strengthened RC beams [PDF]

Proceedings of the Institution of Civil Engineers - Structures and Buildings, 2016
Consideration of moment redistribution (MR) in the design of continuous reinforced concrete (RC) beams results in an efficient and economical design. Adding fibre-reinforced polymer (FRP) materials to reinforced structures to enhance flexural capacity leads to a reduction in ductility, such that design standards severely limit use of the MR in their ...

Stress Redistribution in Statically Indeterminate Corroded Reinforced Concrete Beams

Железобетонные конструкции
The paper deals with the issues of bending moment redistribution in statically indeterminate corroded reinforced concrete beams. It is noted that the ability of a reinforced concrete beam to rotate is crucial for both operational and limit states, as it ...

Premature destruction of two-span RC beams exposed to high temperature caused by a redistribution of shear forces

Journal of Civil Engineering and Management, 2017
When multi-span RC elements are exposed to fire one usually observes a yielding of span cross-sections while a safety reserve of support cross-sections is still significant. Due to this phenomenon a redistribution of bending moments occurs and the values

Moment redistribution in cold-formed steel continuous beams [PDF]

Thin-Walled Structures, 2016
Abstract The external envelope of steel framed industrial buildings normally involves the use of purlins and rails spanning between the main hot-rolled frames to support the roofing/cladding. These purlins are typically light-gauge cold-formed steel members of complex shape for which the thin-walled nature of the material means that local ...

Moment Redistribution in UHPC Continuous Beams Reinforced with High-Strength Steel Bars: Numerical Investigation and Prediction Model

Buildings
Considering moment redistribution in the design of ultra-high-performance concrete (UHPC) statically indeterminate structures can fully exploit the load-bearing potential of members, simplify reinforcement details, and save construction costs. Due to the

Cell‐cycle‐specific lesion evolution rather than inhibition of double‐strand‐break repair underpins cisplatin radiosensitization

Molecular Oncology, EarlyView.
We analyze cisplatin–DNA adducts (CDAs) and double‐strand breaks (DSBs) in a cell‐cycle‐dependent manner. We find that CDAs form similarly across all cell cycle phases. DSBs arise only in S‐phase. CDAs might not directly impair DSB repair, but S‐phase DSB lesions evolve in the presence of CDAs and disrupt repair in G2, also causing radiosensitization ...
