Behaviour of reinforced concrete deep beams
Twenty five model beams were progressively loaded to failure in order to investigate the influence of the following variables on the behaviour of reinforced concrete deep beams : i) Concrete compressive strength ii) Reinforcement iii) Geometry. The model beams were all of 1500mm span, with a depth …

Automated Design of Reinforced Concrete Deep Beams
… in reinforced concrete structures. Deep beam were chosen because their behaviour encompasses all the difficulties associated with modelling reinforced concrete structures under a state of generalised stress, and also for their ease of manufacture and testing. The rationale for the …

Behaviour of continuously supported self-compacting concrete deep beams
… structural behaviour of continuously supported deep beams made with SCC. A series of tests on eight reinforced two-span continuous deep beams made with SCC was performed. The main parameters investigated were the shear span-to-depth ratio, the amount and configuration of web reinforcement and …

Shear strength and bearing capacity of reinforced concrete deep beams
Reinforced concrete deep beans with small span/depth ratios usually fail by crushing of concrete in the bearing zone above the supports. In order to increase the load carrying capacity of deep beans, bearing strength around the supports should be enhanced. The first part of this study involved the …

Behaviour of continuous concrete deep beams reinforced with GFRP bars
… bars (GFRP) reinforced continuous concrete deep beams. For this purpose, experimental, analytical and numerical studies were conducted. Nine continuous concrete deep beams reinforced with GFRP bars and one specimen reinforced with steel bars were experimentally tested to failure. The …

Shear strengthening and repair of deep beams with and without web reinforcement using near-surface mounted CFRP bars
… structural concrete elements including deep beams. In this research, the behaviour of deep beam strengthened with carbon fiber reinforced polymer (CFRP) as Near Surface Mounted (NSM) bars was studied. Five groups of deep beams i.e. G1, G2, G3, G4 and G5 were studied. Each group of deep …

Numerical study on shear strengthening of reinforced concrete (RC) deep beams with and without stirrups using near-surface mounted FRP bars
… on NSM strengthening using FRP bars on RC deep beams are available. In this research, a numerical investigation was carried out on RC deep beams strengthened in shear with NSM-FRP bars using the ABAQUS

Kinematics-Based Modelling of Deep Transfer Girders in Reinforced Concrete Frame Structures
Reinforced concrete deep beams often carry heavy loads as transfer girders in high-rise buildings, pile caps in bridges or other important structural members. Due to their small slenderness, they exhibit shear failure with disturbed deformation patterns differently from slender beams. Many …

Behavior of Deep Reinforced Concrete Beams under Monotonic and Reversed Cyclic Load
Non-slender reinforced concrete beams find extensive application in cases where heavy loads need to be transferred over a given span. The safety of this kind of structural elements is often critical for the safety of the structure as a whole. The research described in this thesis is devoted to …

Comparison of design methods for shear in reinforced concrete beams
… the design of reinforced concrete slender and deep beams. The results of this study suggest that the truss model is better suited for the design of deep reinforced concrete beams because it models the dominant mechanism that happens in the beam which is the force transfer from load to reaction …

Modelling Reinforced and Prestressed Concrete Structures Subjected to Shear and Torsion
… provisions. To assess the nonlinear response of beams subjected to the six stress resultants, a companion method to Shell II is presented, it is called VAST II. The finite element program is based on the variable angle space truss model for beams and can be used to rapidly model the full …

Static and Dynamic Response of Elastic Skeletal Structures using an Enhanced Beam Element
… elastic instability of slender beams is also investigated. The buckling loads associated with this type of analysis are computed in the same manner as for the natural frequencies. The use of the new element is extended to a space frame with asymmetrical loading.<br/><br/>The free …

Shear strengthening of RC beams using carbon fiber reinforced polymer laminates
… In order to investigate the shear behavior of RC beams with externally bonded CFRP shear reinforcement, experimental programs as well as analytical studies were conducted in this research. The research consists of three parts. They are 1). Regular beams with CFRP shear strengthening; 2). Deep …

C-Grid as Shear Reinforcement in Concrete Bridge Girders
… its development length. Four 18 ft long 19 in. deep beams, modeled after prestressed Bulb-T beams, were created to test the C-Grid, as well as steel and CFCC stirrups. The beams were loaded with a single point load closer to one end to create a larger shear load for a given flexural moment. …

Shear strength of reinforced concrete wall-beam structures: upper- bound analysis and experiments
… of previous work on shear failure in R. C. beams demonstrates the need for a rational analysis approach which broadly represents the important physical characteristics and mechanics of shear failure and which can reliably predict the shear capacity. The rigorous theory of plasticity in shear …

Shear strengthening of reinforced concrete beams with bi-directional carbon fiber reinforced polymer (CFRP) strips and CFRP anchors
… to evaluate the behavior of reinforced concrete beams strengthened in shear with bi-directional CFRP strips and CFRP anchors so that the findings from the previous work can be understood and implemented. Four 24 in. deep T-beams were fabricated at the Phil M. Ferguson Structural Engineering …
