Provision of openings in serviceable reinforced concrete beams may result in a substantial decline in the beam's capacity and integrity; pointing out the necessity of opening strengthening. The present study investigates the response of reinforced concrete T-beams with strengthened openings disposed in shear span. The experimental program consisted...

A parametric study using Non-Linear Finite Element Analysis (NLFEA) was carried out to investigate the response of slabs on grade to industrial trucks with single wheel axles loading. The studied parameters were the load position in relation to slab edges, slab proportions, the reinforcement content, method of reinforcement arrangement, and the mod...

The behavior of high strength concrete colu mns; HSCC with steel fibers under cyclic loading was investigated. Fourteen half-scale column specimens were tested under cyclic lateral load. The key variables covered in this investigation include the steel fibers ratio ranging from 0.00% to 1.50%. The concrete st rength varied from 50 MPa to 100 MPa. T...

A practical least cost design of pre-cast reinforced ledge beams is presented , The objective function is chosen to be-. the cost of the beams. The design variables are represented by the cross-sectional dimensions and flexural , shear,. and torsion reinforcements. All structural behavior constraints in accordance with the ultimate strength limit s...

A non-linear finite element analysis was carried out to conduct a parametric study on the response of slabs on grade to industrial trucks with single wheel axles loading. The study covers the load position in relation to slab edges, slab proportions, the reinforcement content and its method of arrangement, and the modulus of subgrade reaction. In t...

A non-linear finite element analysis was carried out to investigate the ultimate behavior of reinforced concrete wall panels with openings subjected to in-plane uniform vertical loads. The loads were applied at an eccentricity of one-sixth of the panel thickness, representing an accidental eccentricity during construction. The panels were analyzed...

A well experimentally correlated method for shear analysis of reinforced concrete corbels is outlined herein. The method was employed to conduct parametric study on the ultimate shear strength of r.c. corbels. The study cover shear span-to-depth ratios between 0.25 and 1.50, horizontal stirrups content ranges. Between 0.25% and 3.0%, main tension r...

The methods specified by the codes of practice for the shear design of rc corbels are based either on shear-friction hypothesis or on strut-and-tie analogy, overlooking the predominant shear action in cc corbel. The shear response is significantly affected by vertical compressive stresses. Based on the modified compression field theory, a method is...

Strictly based on experimental evidence, a non-linear material model is presented for concrete subjected to membrane stresses. The model assumes a smeared rotating crack approach, tension stiffening, stress degrading effect for concrete parallel to the crack direction, and shear retention of concrete on the crack surface. In addition, the concrete...

Slender and thin-walled forms of construction are a natural choice for any large-scale structure employing reinforced concrete. Reinforced concrete flanged beams provide structural strength and stability, and their applications range from buildings, offshore structures, flotation units for housing in marshy land to floating hotels. Tests were carri...
