The article discusses the fragility assessment of reinforced concrete bridges exposed to seismic loads and corrosion over time.

 It examines the effects of these factors on the safety and performance of the bridges, and suggests methods for assessing and mitigating the risks associated with them.

 Overall, the article highlights the importance of considering the long-term effects of seismic loads and corrosion in the design and maintenance of reinforced concrete bridges.

Description

The paper aims to discuss the advantages and disadvantages of the double composite section in high-speed railway bridges from the design, construction and maintenance point of view. The paper is centred around the differences between single and double composite sections.

In engineering practice, fiber addition is a frequently used method to improve the tensile property of asphalt mixture.

The results indicated that asphalt mixture reinforced with 0.50 wt% granular lignin fiber exhibited ideal direct tensile fatigue performance with respect to fatigue life and accumulative dissipated energy.

Researchers in the UAE and Egypt found the iron-based shape memory alloy can help strengthen reinforced concrete beams. Researchers wrote "it can be concluded that using Fe-SMA bars embedded in a shotcrete layer attached to the beam's soffit is a viable and promising strengthening strategy."

Dynamic Response of Reinforced Recycled Aggregate Concrete Pavement under Impact Loading

Author(s): Jifeng Yuan, Jin Wu, Tian Su, 5ORCID andDadi

Episode Info:

Chinese researchers compared four reinforced recycled aggregate concrete pavements with varying thickness and ratios of reinforcement and one reinforced normal concrete pavement to determine its potential use for airport runway pavement.

 Researchers concluded the dynamic performance of reinforced recycled aggregate concrete pavement was worse than reinforced normal concrete due to lower elastic modulus and weaker interfacial transition zone, though performance improved with increasing thickness and reinforcement ratio.
