چکیده

Abstract Apart from the general state of the tendon the quantity of the stress in the prestressed steel is of prime importance for the safety assessment of prestressed structures and/or anchor systems. On account of precaution reasons it was necessary to create a reliable, sturdy and competitive measuring device for the direct stress monitoring in prestressing steel elements being used in sensitive infrastructure buildings and other building structures subjected to high demands as e. g. bridges.

Influence of changes in the prestress force on dynamic specifications of the prestressed concrete beam

Pre-stress techniques tend to increase cross-sectional capacity and optimize design. Such features have made these techniques rather popular. Over time, these structures tend to fail, and the reduction of pre-stress force over the lifetime of the structure is said to be one of the most significant destructive factors in these structures. This decrease in force occurs due to various reasons. In ...

Torsional Waves in Prestressed Fiber Reinforced Medium Subjected to Magnetic Field

The propagation of torsional waves in a prestressed fiber-reinforced half-space under the effect of magnetic field and gravity has been discussed. The problem has been solved analytically using Whittaker function to obtain the exact solution frequency equations. Numerical results for stress, gravity and magnetic field are given and illustrated graphically. Comparisons are made with the results ...

A wireless micro-sensor for simultaneous measurement of pH, temperature, and pressure

In response to a magnetic field impulse, magnetostrictive magnetoelastic sensors mechanically vibrate. These vibrations can be detected in several ways: optically from the amplitude modulation of a reflected laser beam, acoustically using a microphone or hydrophone, and by using a pickup coil to detect the magnetic flux emitted from the sensor. Earlier work has shown that the resonant frequency...

Ultimate Tendon Stress in CFRP Strengthened Unbounded HSC Post-Tensioned Continuous I-Beams

The use of unbounded tendons is common in prestressed concrete structures and evaluation of the stress increase in unbonded tendons at ultimate flexural strength of such structure has posed a great challenge over the years. Based on the bending experiment for two-span continuous post-tension beams with unbounded tendons and externally applied CFRP sheets, the monitoring of the stress increment ...

Blocking Non-Specific Binding for Phage-Based Magnetoelastic Biosensors

The magnetoelastic (ME) biosensors are used to detect pathogen in fresh juice or milk by solenoid coil, and also developed for real-time, direct pathogen detection on food surfaces by surface-scanning coil. This paper presents blocking effect of different reagents on non-specific binding for detecting Salmonella typhimurium in apple juice using phage-based magnetoelastic biosensors. Three diffe...
