Shear Performance

This paper presents a study of shear behaviour of reinforced concrete beams. The major parameters used were type of shear reinforcement, namely stirrups alone, wire mesh alone and combination of both wire mesh and stirrups as shear reinforcement. The replacement of wire mesh was done on the basis of weight with stirrups. The experimental program includes four beams. All the beams were tested using two point loading system. It is evident from the result that the use of wire mesh enhanced improved shear performance and bearing capacity in the examined beams. Beams with wire mesh as shear reinforcement and combination of both wire mesh and stirrups exhibited some amount of increase in shear capacity with respect to the beams with stirrups alone as shear reinforcement. Furthermore beams with wire mesh and combination of wire mesh and stirrups as reinforcement exhibited less number of crack patterns compared beams with stirrups.

Identical Series

This paper presents test results of eight large-scale reinforced concrete flat plate edge connections. The test specimens consisted of two identical series. Each series consisted of four specimens, two with openings, in the vicinity of the column, and the other two without openings. One of the specimens without an opening contained shear studs as shear reinforcement. The tests were designed to study the effect of high moment-to-shear ratio on the punching shear behaviour of the slab-column edge connections with openings. Each series was subjected to a different moment-to-shear ratio. The test parameters were the location of openings around the column, the shear reinforcement, and the moment-to-shear ratio. The openings in the specimens were square with the sides parallel to the sides of the column. The square dimension of the openings (150 × 150 mm) was 60% of the square column dimension. The slabs contained typical flexural reinforcement (ACI 318-95 and CSA A23.3-94) with the additional reinforcement added on the sides of the openings (equivalent to that interrupted by an opening). The design procedures in the Canadian and American codes (CSA A23.3-94 and ACI 318-95) are discussed and compared with the test results.Key words: columns, edge connections, flat concrete plates, punching shear, shear strength, high moments, openings, failure, shear reinforcement, reinforced concrete.

Shear Performance

The shear performance of reinforced concrete beams with rectangle cross-section and two different continuous rectangular spiral shear reinforcement under monotonous loading is numerically evaluated. Further, the behaviour of two continuous shear reinforcement systems named, “Single Square Spring Shear Resistance System” (SSSSRS) and “Double Square Spring Shear Resistance System” (DSSSRS) as transverse reinforcements are compared with conventional discontinuous system “Stirrups”. The finite element study includes three (3) beams. The results clearly show that the application of continuous shear reinforcement system delivered improved shear behaviour and enhanced bearing capacity in beams. Beams with Single Square Spring Shear Resistance System (SSSSRS) and Double Square Spring Shear Resistance System (DSSSRS) exhibited 14.4% and 19.8% increased shear performance in comparison with conventional control beam. It was concluded that under the same deflection higher forces was achieved for “Single Square Spring Shear Resistance System” (SSSSRS) and “Double Square Spring Shear Resistance System” (DSSSRS) compared to control specimens.

Concrete Damaged Plasticity

The problem of damage accumulation in fiber-reinforced concrete to structures supporting underground workings and tunnel linings against dynamic loading is insufficiently studied. The mechanical properties were determined and the mechanism of destruction of fiber-reinforced concrete with different reinforcement parameters is described. The parameters of the Concrete Damaged Plasticity model for fiber-reinforced concrete at different reinforcement properties are based on the results of lab experiments. Numerical simulation of the composite concrete was performed in the Simulia Abaqus software package (Dassault Systemes, Vélizy-Villacoublay, France). Modeling of tunnel lining based on fiber-reinforced concrete was performed under seismic loading.
