Shear behaviour and stiffness of naturally cemented sands
The behaviour of natural soils is highly influenced by structural features arising from their geological history and was recognised to lie outside current frameworks which account only for the stress-volume state of the soil. The objective of the research was to compare the shear behaviour and …

THE SHEAR BEHAVIOUR OF THE REINFORCED CONCRETE FOUR-PILE CAPS
… BS5400 and BS8110 in the prediction of the shear capacity of 2-way spanning reinforced concrete pile caps from bending theory-based empirical design formulae. This causes designers difficulty to predict an accurate shear capacity of the pile cap. The inherently empirical character of the …

Distributed Sensing to Assess the Shear Behaviour of Reinforced Concrete Beams
… technologies was undertaken to investigate the shear behaviour of reinforced concrete (RC) beams. In the first test series, seven reinforced concrete specimens with different stirrup spacing and longitudinal reinforcement ratios were instrumented with nylon coated FOS and tested in three point …

Laboratory Investigation of Shear Behaviour in Rock Joints Under Varying Boundary Conditions
… and govern the material response. Discontinuity behaviour can have a large impact in geotechnical design, and therefore it is essential to determine their geomechanical properties in order to predict rockmass behaviour and prevent any potential failure that would pose a threat to personnel safety …

Shear Behaviour in Slender Reinforced Concrete Beams with and without Transverse Reinforcement
This study investigates shear crack behaviour in slender reinforced concrete (RC) beams, focusing on the critical shear crack (CSC) geometry and its impact on crack kinematics and shear transfer mechanisms. Existing models often oversimplify CSC shape assumptions, potentially leading to …

Experimental study of shear behaviour of high density polyethylene reinforced sand under triaxial compression
… soil to increase its engineering properties like shear strength, settlement, cohesion and bearing capacity. In consideration of this, a series of triaxial tests were undertaken to investigate the reinforcing effect of High-Density Polyethylene (HDPE) plastic material in Cape Flats sand, …

An experimental study and finite analysis of punching shear failure in steel fibre-reinforced concrete ground -suspended floor slabs
… using steel fibre-reinforcement on the punching shear behaviour of ground-suspended slabs with internal columns. The main objectives of this research were to develop a constitutive model for steel fibre-reinforcement (SFRC), to study experimentally the punching shear behaviour of SFRC with no …

Behaviour of lightweight concrete beams strengthened with carbon fibre reinforced polymer in shear
… ailing reinforced concrete structures, for both shear and flexure. This technology provides unique features compared with conventional retrofitting systems. Among these FRP has good corrosion resistance, lightweight and excellent mechanical properties. Furthermore, the manual lay-up system allows …

On The Shear Strength Of Partially Grouted Concrete Masonry
Masonry shear walls are one of the most common structural elements in buildings. The in-plane shear capacity of load-bearing walls is of great importance in the seismic design of structures. This study focuses on the shear behaviour of wide-spaced reinforced partially grouted (WRPG) concrete …

Optimum shear strengthening of reinforced concrete beams
… polymer (CFRP) straps can be used to strengthen shear deficient reinforced concrete (RC) structures. The strengthening system is associated with a number of parameters including the number of straps, strap locations, strap stiffness, and strap prestress. The initial goal of this research was to …

Modelling Reinforced and Prestressed Concrete Structures Subjected to Shear and Torsion
… require the assessment of members subjected to shear and torsion. To develop a better understanding of the behaviour of such structures, twelve shell element tests were conducted to investigate the influence of combined loads, reinforcement ratios and concrete strength on shear and torsion …

Monolithic beam to external column joints in reinforced concrete
… HSC [1]. However, there are concerns about the shear behaviour of HSC beams and BCJ used in the construction of these buildings. HSC beams have equal or less shear resistance compared to normal strength concrete (NSC) beams [2], and the brittleness of HSC material could be unsuitable for BCJ as …

Experimental and Theoretical Investigations of a New Flat Slab System Incorporating GFRP Stay-In-Place Structural Forms and Embedded I-Beams
… of the floor were investigated. Flexural behaviour in the direction transverse to the I-beams was investigated in the positive and negative moment regions using 2,575×610×225 mm slab segments, incorporating bonded connections and away from connections. A design-oriented analytical model …

Continuity development between precast beams using prestressed slabs, and its effect on flexure and shear
… The effect that such a slab has on flexural and shear behaviour of the bridge deck has been studied both analytically and experimentally by considering composite beams based on M-8 standard precast beam section. Comparison of the design of bridge decks with a prestressed slab and a reinforced …

Shear Strengthening of Reinforced Concrete Beams Using Externally Bonded Carbon Fibre Reinforced Plates
… aim of this study was to investigate the behaviour of reinforced concrete beams strengthened in shear by the addition of Carbon Fibre Reinforced Plastics (CFRP). An experimental programme was devised to investigate the shear behaviour of reinforced concrete beams strengthened by the …

Structural Behaviour of Self Consolidating Steel Fiber Reinforced Concrete Beams
When subjected to a combination of moment and shear force, a reinforced concrete (RC) beam with either little or no transverse reinforcement can fail in shear before reaching its full flexural strength. This type of failure is sudden in nature and usually disastrous because it does not give …

Kinematics-Based Modelling of Deep Transfer Girders in Reinforced Concrete Frame Structures
… Due to their small slenderness, they exhibit shear failure with disturbed deformation patterns differently from slender beams. Many experiments have revealed the complexity of the shear mechanisms of deep beams, and a number of formulations and models have been proposed attempting to explain …

Biocementation of Road Foundations: Element Testing, Physical Modelling, and Micro-Scale Characterisation
… triaxial tests were conducted to examine the shear behaviour of uncemented and biocemented aggregates. The observed changes in stress-strain responses, strength and stiffness evolution, and stress dilatancy are consistent with those reported for biocemented and conventionally cemented soils. …
