COMPARISON BETWEEN TWO MODELING ASPECTS TO INVESTIGATE SEISMIC SOIL STRUCTURE INTERACTION IN A JOINTLESS BRIDGE

, 2019
Seismic waves propagate through a series of rock and soil layers before they interact with the foundation and superstructure. Besides the original characteristics of the earthquake motion at the instant of fault rupture, it is also important how the soil

Numerical investigation on primary and secondary cracks in thick concrete members

Structural Concrete, Volume 27, Issue 1, Page 96-110, February 2026.
Abstract This study investigates the crack formation process in thick reinforced concrete members subjected to imposed deformations, focusing on the development of secondary cracks in addition to geometrically set primary cracks. A validated nonlinear fracture‐plastic finite element model is used to analyze the influence of reinforcement layout, member

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.

Bending performance of prefabricated ultra-thin UHPC unit plate reinforced orthotropic steel bridge decks

Frontiers in Materials
To address the challenges related to lengthy construction period, complex maintenance requirement, and the elevated risk of shrinkage cracking associated with cast-in-place UHPC reinforcement of orthotropic steel bridge decks. This paper proposes a novel

Simplified Material Solution for Orthotropic Symmetrical GFRP Laminates for Structural Facades

Advances in Civil Engineering, Volume 2019, Issue 1, 2019., 2019
GFRP (glass‐fiber‐reinforced polymer), as a composite material, possesses many favorable properties including high strength and low weight and is amenable to unique processing methods; therefore, it is a potential free‐form surface material. However, the complex design theory owing to anisotropy limits its application.

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 ...

Experimental and Numerical Analysis and Prediction of Ground Vibrations Due to Heavy Haul Railway Viaduct

Mathematical Problems in Engineering, Volume 2019, Issue 1, 2019., 2019
The ground vibration wave induced by the viaduct section of the heavy freight wagons is transformed into the ground vibration problem under the condition of point source excitation after it is transmitted to soil through pier. When the speed and axle load of wagon become larger and larger, the impact on the surrounding buildings will also increase.

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
