Finite element modelling of shear connection for steel-concrete composite girders
… package ABAQUS was used to conduct the analysis. Push-off tests with both types of slabs were simulated taking into consideration all material nonlinearities of the components. The models are able to predict the headed shear stud capacity, the load-slip characteristic of the shear connection and …

Evaluation of deck fasteners functioning as shear connectors for composite steel joists
… steel joists is studied. Results of thirty-six push-off tests are evaluated in terms of strength and behavior. Six types of deck fasteners are considered. They are: 1. #12-24 Teks/5 self-drilling, self-tapping screws. 2. 1/4-14 Teks/3 with a 1 1/4 in. stand-off sleeve. 3. 1/4-14 Teks/3 with a 1 …

Behaviour of demountable shear connectors in composite structures
… shear connectors in composite structures through push off tests and composite beam tests. Push off tests were conducted to examine the shear strength, stiffness and ductility of demountable shear connectors in composite structures. The experimental results showed that demountable shear connectors …

Horizontal Shear Transfer Between Ultra High Performance Concrete And Lightweight Concrete
… Ductal® and Lightweight concrete. Twenty-four push-off tests were performed to determine if the current horizontal shear design equations could accurately predict the horizontal shear strength of composite Ductal® and Lightweight concrete sections. Effects from various surface treatments, …

Interface Shear Strength in Lightweight Concrete Bridge Girders
… and normal weight concrete. Thirty-six push-off tests were performed to determine if the current code equations accurately predict the horizontal shear strength of precast girders and cast-in-place decks for both normal weight and lightweight concrete. The different test series …

Horizontal Shear Connectors for Precast Prestressed Bridge Decks
… the main impetus for this project. A total of 36 push-off tests were performed to develop a method for quantifying horizontal shear strength and to recommend the best practice for the system. Test parameters included different haunch heights, different grout types, different amount and different …

Horizontal Shear Transfer for Full-Depth Precast Concrete Bridge Deck Panels
… predicted by current equations. A total of 29 push off tests were performed to quantify peak and post-peak shear stresses at the failure interface. The different series of tests investigated the surface treatment of the bottom of the slab, the type and amount of shear connector and a viable …

Recommendations for Surface Treatment for Virginia Inverted T-Beam Bridge System
… ten different surface textures was tested using push-off tests to determine which interface roughening methods would prove adequate for use in the bridge system. The strength was found to depend on both the amplitude and the geometry of the undulations on the beam-to-slab interface. Using this …

Shear and Peel Stresses at the Interface between Hollowcore Slabs and the Topping Concrete
… surface finishes. Three types of tests were performed: pull-off, push-off and full-scale. They provided an overall understanding of the interfacial shear and peel behaviors at the interface between hollowcore slabs and the topping concrete. The tested slabs were found to sustain …

Experimental Evaluation and Analytical Modeling of Shear Bond in Composite Slabs
… property derived from full scale performance tests. In numerical modeling, the interaction property is obtained from a variety of elemental push off tests which, for the most part, do not represent actual slab bending. This research comprises experimental, analytical and numerical …
