Pulse compression technique applied to ultrasonic nondestructive testing of concrete
The pulse compression technique is successfully and widely used in many fields for improving the signal to noise ratio (SNR); which is especially useful when the environment is noisy and the SNR is poor. Since high frequency ultrasound is strongly attenuated in concrete, only low frequency ultrasound can be used in ultrasonic nondestructive testing (NDT) of concrete. In this study the pulse com...
متن کاملSeismic Behavior of Steel Reinforced Concrete Beam-Columns and Frames
The ability to perform accurate nonlinear simulations is a key component in the assessment of the behavior of seismic force resisting systems. A three-dimensional distributed plasticity formulation for composite beam-columns suitable for nonlinear static and dynamic analyses of composite seismic force resisting systems has been developed. New uniaxial constitutive relations are developed for th...
متن کاملExperimental and Analytical Study on Reinforced Concrete Deep Beam
ABSTRACT: Several reinforced concrete deep beams with different L/D ratios (1.5, 1.6, 1.71) were cast and tested in order to investigate the strain distribution pattern at mid-section of the beam. This paper describes analysis of deep beams subjected to two point loading with three different L/D ratios (1.5, 1.6, 1.71) using Non-linear Finite element method (ANSYS 9.0 software). In ANSYS 9.0 so...
متن کاملTapered Polymer Fiber Sensors for Reinforced Concrete Beam Vibration Detection
In this study, tapered polymer fiber sensors (TPFSs) have been employed to detect the vibration of a reinforced concrete beam (RC beam). The sensing principle was based on transmission modes theory. The natural frequency of an RC beam was theoretically analyzed. Experiments were carried out with sensors mounted on the surface or embedded in the RC beam. Vibration detection results agreed well w...
متن کاملAthletics impulsively traits: A comparison between contact and noncontact sports
The aim ofthisstudy was to investigatedifferentaspects ofimpulsivityin the athletes of contact and non-contactsports. volunteer participants were 60 athletes of contact (age: 25.9±4.6 years) and non-contact (age: 27.6±4.9 years) sports. Participants were asked to complete the Barratt’s Impulsivity Scale (BIS-11) and participate in continuous performance test(CPT). Multivariate analysis of varia...
