Analysis of the shear stress at the interface between steel and cement grout

Abstract

The selection of materials for bridge construction is crucially based on cost-effectiveness and efficient on-site assembly. The integration of prefabricated slabs in mixed bridges expedites construction but presents challenges with conventional connections, often prolonging site work. Addressing this challenge, a novel adhesive connection has emerged as a structural innovation, aiming to establish a robust bond between steel and prefabricated concrete slabs, there by optimizing construction timelines.This study scrutinizes the performance of the cement-steel interface under shear forces. Through numerical analysis, our research investigates the distribution of shear stress and normal stress within the compact element of the assessed interface. Methodologically, our analysis initially utilized Catia software for conception, followed by transforming the model into Ansys software for simulation purposes. This process elucidates the behavior and durability of the adhesive connection.Our research specifically focuses on two geometric configurations: AR1, where the grooves of the steel plats are oriented perpendicular to the applied loads, and AR2, where the grooves run parallel to the applied loads, shedding light on the distinctive advantages of this innovative connection approach.
