The study aimed to contribute to condition assessments of historic bridges in Izmir, Turkey and the estimation of their predictable functional lifetime after the Samos earthquake. This document is a summary of the study into the reliability of Non-Destructive Techniques (NDT) for testing the state of different historic bridges impacted by the Octob...

Over the past years, a remarkable number of bridges have been collapsed or failed worldwide, underlying the growing importance of condition assessment of bridge structures within the context of health monitoring of structures and their life cycles become important to prevent such events. If utilised correctly, advanced Non-Destructive Techniques (N...

This paper reports on the fundamental role played by Ground Penetrating Radar (GPR), alongside advanced processing and presentation methods, during the tunnel boring project at a Dam and Hydro–Electric Power Station. It identifies from collected GPR data such issues as incomplete grouting and the presence of karst conduits and voids and provides fu...

In this paper, we aim to share the experiences, lessons learned from the summer school entitled ‘Spatial Information Technologies in Archeology’. The course was jointly organized by Akdeniz University and Antalya Bilim University between April 9-12th 2018 at the Patara Ancient Site, which celebrates its 30th year anniversary of excavations. The cou...

Ground penetrating radar (GPR) uses data collected with the aid of electromagnetic waves transmitted into a structure by antenna to assess and monitor the structural health of many different kinds of civil infrastructure. With GPR technology promoting their system with promises of the achievement of in excess of 1000 sample points per scan, this re...

This study presents an examination and a presentation of ground-penetrating radar (GPR) on a heavily used high-speed railway bridge in Turkey. This study also considers GPR mapping using two different antennas (2 GHz and 500 MHz), and their reliability in terms of locating subsurface features, such as rebar (lower and upper reinforcement) and the p...

Ground-penetrating radar (GPR) uses electromagnetic waves to investigate the structures. In this investigation method, an electromagnetic wave is transmitted using an antenna and the received signal is recorded. Detection of beam positions in this GPR data requires the skills of a trained human operator. This study utilized a multi-layer neural net...

This paper describes the specific application of the non-destructive testing methods of visual inspection and ground penetrating radar (GPR) to a pedestrian bridge in Izmir, Turkey. The paper concentrates on the implementation of a deconvolution neural network (DNN) which is a procedure that employs neural network algorithms. By introducing collect...

Structural Health Monitoring (SHM) is commonly used in the health assessment of wind turbines. The system is installed during construction of the structure and consists of wired sensors connected to a central data acquisition unit via cables. In most cases, the data acquisition unit is located on the wind turbine itself. SHM is verified by comparis...

Ground penetrating radar (GPR) is a highly researched area; however, despite this, there is a lack of knowledge about the well-known problem of moisture distorting the results of GPR surveys. This research analyses the results of a GPR survey on a Case Study Bridge structure in order to analyse this effect, specifically when checking for the positi...

This study aims to enhance the body of knowledge available in relation to the mechanical performance of historical structures and the assessment of the expected service life of such structures. The reliability of non-destructive techniques (NDT) is examined, in particular in connection with the technique's application to a historic Ottoman building...

According to the website of Mary Robinson Foundation for Climate Justice, 2.7 Million people worldwide, most of them being extremely poor and 1.3 billion of them with no access to electricity, rely on solid fuels such as traditional biomass and coal for cooking and heating. In this world where a number of experts are concentrating their research on...

Considerable research into the area of bridge health monitoring has been undertaken; however, information is still lacking on the effects of certain defects, such as moisture ingress, on the results of ground penetrating radar (GPR) surveying. In this paper, this issue will be addressed by examining the results of a GPR bridge survey, specifically...

In this paper two protocols of Wireless Sensor Networks (WSN) are examined through both a simulation and a case study. The simulation was performed with the optimized network (OPNET) simulator while comparing the performance of the Ad-Hoc on demand Distance Vector (AODV) and the Dynamic Source Routing (DSR) protocols. This is compared and shown wit...

This paper presents the results of the application of several Non-Destructive Techniques (NDT) on the Pentagon Road Bridge, in Chatham, Kent, England. This provides crucial structural information such as rebar position, moisture ingress and deflection. A FEM (Finite Element Model) of the bridge was created using data from the visual inspection and...

The main objective of this investigation is to provide an alternative method for damage detection and assessment of bridge structures based on comparisons between Finite Element (FE) modelling/analysis and field data. The field data reported in this paper refers to the application of a non-destructive structural testing method (IBIS-S sensor system...

This paper presents the essence of two case studies by the authors on two major bridges in the UK. The first case study reports on the applications of GPR and associated work carried out on the Forth Road Bridge near Edinburgh, Scotland, with the main objective of identifying possible structural defects including damaged rebar and moisture ingress...

Inspection and assessment of bridge structures within the context of health monitoring of structures as well as the life cycle of structures is of paramount importance for structural engineers and bridge owners. No doubt the early detection of structural defects in particular internal structural elements such as bridge deck delamination, formation...
