“…Two types of shear connectors in the study are headed studs and perfobond strips, and their layout corresponds to the cast-in-place and precast slab construction methods. The material model of truss element for the shear connector is established based on the nonlinear relationship between shear force and slip of the head studs specified in Japanese design standard JSCE [8] and perfobond rib shear connector in the author' s previous study [9,10]. The results on the load -deflection relationship, the stress behavior of steel girder and concrete slab, and the slip behavior of the shear connector are discussed.…”

The key to improve the accuracy of behavior analysis of the steel composite girder lies in the reasonable modelling the intergration between the reinforced concrete slab and the steel girder. Based on design requirements and construction methods, the type and layout of the shear connectors between the concrete slab and the steel girder are different, significantly affecting the behavior of the composite girder. This study is conducted to (i) investigate the applicability of a truss element available in the popular simulation software Abaqus in modelling the shear connectors of composite girders, (ii) compare the flexural behavior of composite girders with different types and layouts of shear connectors. Two types of shear connectors considered in the study are headed studs and perfobond strips, and their layout corresponds to the construction methods using the cast-in-place and precast concrete slabs. The study results show that a truss element can be used to simulate the shear connector behavior through reasonable assignment of its shear force-slip relationship. With the design principle that the total shear capacity of the shear connector per unit length remains constant, the nonlinear behavior of the composite girder is significantly affected by the type and layout of the shear connectors.

“…These reinforcing materials are generally added in the form of fibers that can be synthetic or natural [23]. The most commonly used synthetic fibers are glass fibers [24], basalt [25], steel [26], carbon [27] and polypropylene [28], which have demonstrated their technical feasibility to improve the mechanical properties of masonry mortars, especially by increasing their flexural strength and decreasing shrinkage [29]. For their part, the most commonly used natural fibers in the manufacture of mortars are hemp [30], coconut [31] and wood [32] fibers, which have also allowed improving the physical and mechanical properties of masonry mortars, although they generally experience lower durability and greater deterioration with the passage of time [33].…”

The reuse of construction and demolition waste is a necessary way to achieve greater sustainability in building, introducing the criteria of the so-called circular economy in the design of the production process of new construction materials. This research focuses on analyzing the properties of mortars made with recycled aggregates from concrete waste and reinforced with aramid fibers. For this purpose, an experimental campaign was carried out, including chemical, physical, mechanical and durability tests, performing a statistical analysis to discuss the different properties analyzed. The results show how the incorporation of aramid fibers in the matrix of cement mortars made with recycled concrete aggregate improves their technical performance and mechanical resistance, thus increasing their application possibilities and achieving similar results in some properties to those obtained with traditional mortars made with natural aggregate.
