Analysis of a reinforced concrete beam in torsion
Eight reinforced concrete beams with two different concrete strengths and four different schemes of reinforcing were tested to failure in pure torsion. SR⁻⁴ strain gages were used to measure the concrete strains at the surface of the test beams. A review of analytical and experimental studies in …

Damage classification in reinforced concrete beam by acoustic emission signal analysis
… (PA) was used to evaluate the reinforced concrete (RC) structure. This study has proposed and tested the absolute energy parameter in the evaluation for determining the damage level in RC structure. In addition, the cracks patterns in RC beam have been identified according to the type of …

Analysing method for acoustic emission clustering system on reinforced concrete beam
… types of damage occurring in reinforced concrete (RC) beam. In spite of these advantages, difficulties still exist in using the AE technique for monitoring applications particularly in analysing recorded AE data due to the large quantity of data involved. Other than that, the main problem …

The upturned concrete beam system : an investigation of structural, environmental, and constructability performance
… building system. Through the use of upturned concrete T-beams, designers created a naturally ventilated workspace that employs the thermal mass of an exposed concrete ceiling. This concrete absorbs heat during the day and is purged at night by cool breezes. This study investigates the inherent …

Joint Shear Behavior of Reinforced Concrete Beam-Column Connections Subjected to Seismic Lateral Loading
An extensive experimental RC beam-column connection database (of 341 subassemblies in total) was constructed. RC joint shear behavior (joint shear stress v. joint shear strain) was described as an envelope curve by connecting key points displaying the most distinctive stiffness changes. At the …

Structural performance of precast self-compacting concrete beam consisiting banana skin powder and coir fibre under flexural load
… waste as a construction material like concrete. The agricultural waste widely used as supplementary cementing material, filler and fibre reinforcement. In this research Banana Skin Powder (BSP) and Coir Fibre (CF) utilized as partially cementing material and filler respectively, to …

Comparative study on the behaviour of concrete reinforced with FRP and steel singly reinforced beams
Maintenance and repair of concrete infrastructure account for a large amount of financial resources. This is due to the deterioration of reinforced concrete through the corrosion of steel reinforcement. The depassivation of the steel creates an environment prone to chloride ingress and carbonation. …

The State-based Peridynamic Lattice Model and Reinforced Concrete Structures
… This assumption is unrealistic for reinforced concrete structures, which become discontinuous as cracks form. Silling has proposed a nonlocal theory called peridynamics and Gerstle has specialized his idea to develop the state-based peridynamic lattice model (SPLM). The SPLM sufficiently models …

Lifting Analysis of Precast Prestressed Concrete Beams
… research study provides a method for predicting beam behavior during lifting, with application in the construction of bridges. A beam lifting cracking limit state is developed based on analytical equations for calculating the roll angle of the beam, the internal forces and moments, the weak-axis …

Structural engineering model of irregular and efficient concrete beams: Application to topology optimized shapes and integrated textile reinforcement
Concrete remains one of the most widely used construction materials due to its strength, durability, and availability. However, it is responsible for a large share of the global carbon emissions. Within the 40% of the global emissions attributed to the building sector, 5-8% alone accounts for the …

Fracture analysis of debonding mechanism for FRP plates
Inevitable flaws in the concrete-FRP interface govern plate debonding, and are not amenable to finite element analysis because the models require far more detail than will ever be available for the interface. This thesis describes a global-energy-balance based fracture-mechanics model for the …
