Thermo-mechanical compatibility of CFRP versus steel reinforcement for concrete at high temperature [PDF]

open access: yes, 2014
Optimization of the design of concrete structures has become a driver for the use of nonconventional reinforcing materials. One example of this is the emerging use of non-corrosive, highstrength, and lightweight carbon fibre reinforced polymer (CFRP ...

Simple and detailed modeling of corrosion‐affected slender shear critical RC beams

open access: yesStructural Concrete, EarlyView.
Abstract The corrosion of steel bars compromises both the safety and the serviceability of reinforced concrete (RC) structures. Consequently, reliable tools are required to estimate the detrimental effects of corrosion on the structural response of RC members subjected to transverse loads.

Structural capacity of precast concrete walls with openings: A parametric study on connection types and reinforcement ratios

open access: yesStructural Concrete, EarlyView.
Abstract The structural role of precast concrete walls with openings is often overlooked in design practice due to concerns about reduced stiffness, stress concentration, cracking around openings, and potential unexpected failure modes under seismic loading.

SHALLOW FLAT SOFFIT PRECAST CONCRETE FLOOR SYSTEM [PDF]

open access: yes, 2014
A precast concrete floor system that eliminates the need for column corbels and beam ledges while being very shallow. The main advantages of the present system include a span to-depth ratio of 30, a flat soffit, economy, consistency with prevailing ...

Sensitivity study on accuracy and relevant parameters in numerical modeling of internal tendon breaks

open access: yesStructural 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‐

Prestress loss of post-tensioned clay diaphragm and fin brickwork [PDF]

open access: yes, 1994
Unlike calcium silicate and concrete block masonry which undergo shrinkage with time, clay brickwork has been known to expand instead. Expansion of brick units in prestressed masonry will cause an increase in the prestressing force instead of prestress ...

Decoupling Seasonal Seismic Velocity Changes on Slow‐Moving Slopes in Southwest China Using Tree Ensemble Machine Learning

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Changes in seismic properties can help assess slope damage, which is influenced by external factors such as temperature, relative humidity, rainfall, air pressure, and local seismicity. However, the contributions of these factors, and how the dominant factor modulates transient and seasonal seismic velocity changes (δv/v $\delta v/v$), remain ...

Deflection control of prestressed concrete elements considering uncertainties

open access: yes, 2019
Excessive deflections can affect serviceability e.g. by causing damage to connecting building components and resulting in problems related to drainage in roof slabs.
