Detection of Concrete Cover of Reinforcements in Reinforced Concrete Wall by Microwave Thermography with Transmission Approach

Hysteretic Behavior of Conventionally Reinforced Concrete Coupling Beams in Reinforced Concrete Coupled Shear Wall

This paper presents the experimental results of four full-scale coupling beams in which only horizontal reinforcements are placed, without diagonal reinforcements, with the aim to develop reinforcement details for coupling beams used in connecting side walls in a wall-slab structural system. Each coupling beam specimen was designed according to the deep-beam design procedure that does not use d...

Review of Active IR Thermography for Detection and Characterization of Defects in Reinforced Concrete

Active thermography methods enable structural investigations of reinforced concrete elements taking into account many different testing problems. The goal of this review is to provide an overview on the state-of-the-art regarding the use of active infrared thermography (IRT) for detection and characterization of defects in reinforced concrete. The paper will provide the physical background, equ...

Cracking of Concrete Cover in Frp Reinforced Concrete Elements under Thermal Loads

Synopsis: The effects of thermal loads on the structural performance of FRP reinforced concrete elements are analyzed in this paper. The difference in transverse coefficient of thermal expansion (CTE) between FRP and concrete causes the presence of tensile stresses within the concrete and, eventually, the formation of cracks when the temperature increases. As part of an inter-university experim...

Damage Detection of Carbon Fiber-reinforced Concrete Under Bending Test

Scale Effect on the Shear Strength of Reinforced Concrete Columns with Termination of Main Reinforcements

A number of RC bridge columns which are similar with the columns which suffered extensive damage during the 1995 Kobe, Japan earthquake due to premature shear failure resulting from the termination of longitudinal reinforcements with insufficient development and the lack of shear reinforcements still exist. To improve the seismic performance, some of them were retrofitted. Evaluation of shear s...
