Advanced control of non‐isothermal axial dispersion tubular reactors with recycle‐induced state delay

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract We develop a delay‐aware estimation and control framework for a non‐isothermal axial dispersion tubular reactor modelled as a coupled parabolic‐hyperbolic PDE system with recycle‐induced state delay. The infinite‐dimensional dynamics are preserved without spatial discretization by representing the delay as a transport PDE and adopting a late ...

Post-fire rehabilitation of reinforced concrete columns: effectiveness of ferrocement jacketing under different cooling regimes

Journal of Engineering and Applied Science
Fire exposure severely reduces the strength of reinforced concrete (RC) columns, with residual performance strongly influenced by cooling regimes. This study examined 27 columns subjected to 150–600 °C, cooled in air or water, and retrofitted with ...

Experimental and Numerical Investigation on the Behavior and Strengthening of Fire-Damaged Reinforced Concrete Walls Using Self-Compacting Concrete Jacketing

Medžiagotyra
Fire exposure significantly compromises the load-bearing capacity of reinforced concrete (RC) structures, highlighting the critical need for effective post-fire rehabilitation strategies. There remains limited knowledge of the post-fire rehabilitation of

Interface slip model for reinforced concrete columns strengthened with concrete jacketing

Revista de la construcción, 2020
Retrofit and rebuilding are two potential solutions for reinforced concrete (RC) structures with columns that have insufficient detailing or strength to withstand seismic loads or other extreme events. Demolition and rebuilding can be expensive and time-consuming. Thus, retrofitting and strengthening of columns can be an efficient solution.

On the preservation of reinforced concrete architectural masterpieces: The challenges of the REcube project

Structural Concrete, EarlyView.
Abstract The preservation of reinforced concrete masterpieces from the 20th century poses a complex challenge. These structures often combine architectural, historical, and technological value, which standard engineering codes and conservation practices are not fully equipped to address. The Erasmus+ REcube project responded to this gap by promoting an

Self-Compacting Concrete Jacketing – Tests and Analysis

AASRI Procedia, 2012
Abstract This study presents experimental and analytical results obtained from the application of a reinforced self-compacting concrete jacketing technique for the rehabilitation of shear damaged reinforced concrete beams. Three shear-dominated beams were initially subjected to monotonic four-point bending loading.

Seismic strengthening of beam-column joints with multidirectional CFRP laminates [PDF]

, 2012
An experimental program was carried out to analyse the potentialities of a technique based on the use of multidirectional CFRP laminates (MDL-CFRP) for the seismic repair and strengthening of reinforced concrete (RC) beam-column joints. This experimental

Computational intelligence model for predicting the compressive strength of FRP‐confined concrete column

Structural Concrete, EarlyView.
Abstract Fiber reinforced polymer (FRP) wrapping technology is commonly used to enhance the compressive strength (CS) of reinforced concrete (RC) members. Accurate prediction of the compressive strength of FRP‐confined concrete columns is crucial for optimizing structural design and helps reduce the time and costs associated with physical testing ...
