Non-linear finite element analysis of reinforced concrete panels and infilled frames under monotonic and cyclic loading. Structures under plane stress loading are analysed up to and beyond the peak load. Non-linear material properties including cracking, crushing and the non-linear behaviour at the interface of members are considered.
… by analysing five reinforced concrete panels, a deep beam, a shear wall, and eight infilled frames. The accuracy of the analytical results was assessed by comparing them with the experimental results and those obtained analytically by other workers and shown to be good. A study of the effects of …

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 …

Shear strengthening and repair of deep beams with and without web reinforcement using near-surface mounted CFRP bars
Shear failure of a reinforced concrete beam is catastrophic because it occurs suddenly and without warning. Recently, CFRP sheets and bars have been rapidly employed in strengthening structural concrete elements including deep beams. In this research, the behaviour of deep beam strengthened with …

Developing and Validating New Bolted End-Plate Moment Connection Configurations
… depths. Hence, it was concluded that two deeper tests need to be performed for this configuration. A full-scale testing program was conducted for ten specimens covering three configurations. The two new configurations (six bolt flush unstiffened and twelve bolt multiple row extended …

Buckling of cantilever thin plate with free end subjected to uniform shear
… in 1899, based on the equilibrium condition of a deep beam. The author baa used the energy method based on the thin plate theory to attack the problem. After the displacement is assumed, the potential energy can be formulated. From the condition that the potential energy assume a minimum value in …

Development and Validation of a Twelve Bolt Extended Stiffened End-Plate Moment Connection
… 30 percent of currently available hot-rolled beam sections. The strength of this configuration is limited by bolt strength. There is a need for a stronger end-plate moment connection, hence the reason for the development and validation of a twelve bolt configuration. Equations were developed …

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 …

CFRP as Shear and End-Zone Reinforcement for Concrete Bridge Girders
… grid was determined. Next, an 18 ft long 19 in. deep beam, modeled after prestressed Bulb-T beams, was created with NEFMAC grid reinforcement. The beam was loaded with a single point load near the support to induce shear failure. Beams were fitted with instrumentation to capture shear cracking …

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 …

Shear strengthening of RC beams using carbon fiber reinforced polymer laminates
… advanced warning, thus it is desirable that the beam fails in flexure rather than in shear. Many existing reinforced concrete (RC) members are found to be deficient in shear strength and need to be repaired. Deficiencies occur due to several reasons such as insufficient shear reinforcement or …
