Study on Mechanical Behavior of Longitudinal Wet Joints of Prefabricated Assembled Beam

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
This study investigates the impact of various interface construction techniques on the bending strength of longitudinal wet joints in bridge superstructures through experimentation. A functional relationship between measured bending strength and theoretical shear strength values is established by finite element simulation.

SSI‐induced seismic earth pressures on an integral abutment bridge model: Experimental measurements versus numerical simulations and code provisions

Earthquake Engineering &Structural Dynamics, Volume 53, Issue 15, Page 4830-4852, December 2024.
Abstract Integral abutment bridges (IABs) generate strong soil–structure interaction (SSI) effects due to their high structural stiffness and transmission of inertial and thermal loads generated at the deck directly to the abutments. Despite an increasing number of experimental and numerical studies available in the literature, there is a lack of ...

Simplified modified tension chord model: An alternative crack width calculation model to Eurocode 2 and fib model codes

Structural Concrete, Volume 25, Issue 6, Page 4586-4608, December 2024.
Abstract This paper proposes a new design code formulation for calculating crack widths for regular and more special reinforced concrete (RC) members. The more comprehensive Modified Tension Chord Model (MTCM) has been simplified (SMTCM) to facilitate an alternative method for calculating crack widths to Eurocode 2 and fib Model Codes.

Chemical prestressing of concrete structures; state of the art review

Structural Concrete, Volume 25, Issue 2, Page 1450-1464, April 2024.
Abstract Chemical prestressing was developed during the 1960s; however, and due to technical difficulties at that time, the technology was not considered as an alternative to conventional prestressing; instead, it was only used as a shrinkage compensating method. Still, recent development in concrete technology encouraged several researchers to revisit

Effect of Stacking Sequence on Mechanical and Water Absorption Characteristics of Jute/Banana/Basalt Fabric Aluminium Fibre Laminates With Diamond Microexpanded Mesh

International Journal of Polymer Science, Volume 2024, Issue 1, 2024.
This research focuses on hybrid woven fibre metal laminates (HWFMLs), specifically on the innovative hybridization of natural woven fibres (NWFs) with aluminium diamond microexpandable mesh (Al‐DMEM) in thin laminates. More specifically, it investigates the effect on the mechanical and water absorption properties of incorporating basalt (B), jute (J ...

Retrofitting of a Multi-Span Simply Supported Bridge into a Semi-Integral Bridge

Applied Sciences
Thousands of multi-span, simply supported beam bridges with short or medium spans have been built in China. They often suffer from problems of cracks in the link slabs over piers, and the deterioration and damage of deck expansion joints at abutments. To
