Real Records Scaling Factors Optimization To Fit The Syrian Design Spectra Using Genetic Algorithm, Seraj Jdyd

Journal of the Arab American University مجلة الجامعة العربية الامريكية للبحوث

After selecting real seismic records it is necessary to scale these records to match the intensity of the earthquake expected for the site. Generally, scaling can be made by ground motions uniform scaling in time domain which is simply scaled up or down the ground motions uniformly to best match (in average) the target spectrum within a period range of interest. It’s an engineer’s job to find the best scaling factors to best match the target spectrum, which is a complex task, so we employed the Genetic Algorithm (GA) in finding those scaling factors to achieve the best ...

Conversion Of Legacy Inspection Data To Bridge Condition Index (Bci) To Establish Baseline Deterioration Condition History For Predictive Maintenance Models., Nicola Ann Stevens, Myra Lydon, Kristopher Campbell, Thomas Neeson, Adelle Marshall, S. E. Taylor

Civil Engineering Research in Ireland 2020

Bridge Management Systems (BMS) have been introduced across the world with the goal of aiding the decisions regarding maintenance, rehabilitation and replacement (MR&R) of bridges. Deterioration modelling is the most important part of the BMS because the ability to predict the future condition is vital as it will determine the quality of the decisions made. Markovian-based models are the most common predictive maintenance tool utilised in existing BMS, by obtaining probabilities of transition of bridge condition from one state to another based on historic bridge inspection data. Prior to the introduction of the Bridge Condition Index (BCI) the use ...

Developing A Common Framework For A Bridge Management System At National Level, Thomas Neeson, Myra Lydon, Kristopher Campbell, Nicola Ann Stevens, Adelle Marshall, Aleksander Novakovic

Civil Engineering Research in Ireland 2020

Transport infrastructure is directly impacted by climate change as extreme weather conditions account for 10-35% of delays/service interruptions to road and rail infrastructure. The current reactive method of maintaining bridges within these infrastructure systems results in a lack of contingency capacity and ultimately a reduced ability to adapt to uncertain future needs. To allow infrastructure providers to prepare for future events, there is a need to develop asset management systems (AMS) with embedded decision-making support which considers factors such as climate change and population growth. A National approach would enable strategic risk assessment to mitigate the consequences of climate ...

Hydraulics Of Scour In The Vicinity Of A Flexiarch Bridge, Prabuddha Sathurusinghe, Gerard Hamill, Su Taylor, Desmond Robinson

Civil Engineering Research in Ireland 2020

Floods and scour are major causes of failure of bridges and with the increase in short-duration and high intensity rainfall events the occurrence of such failures is increasing. While standard free flow scour at bridge piers is an extensively researched area, the increased scour that occurs when the upstream water level is at or above the crown of an arch bridge (pressure-flow scour) is comparatively less well studied. As the frequency and magnitudes of floods increase, more bridges may be at a higher risk of being subject to pressure-flow scour. A modern masonry arch bridge system called the ‘FlexiArch’, that ...

Civil Engineering Research in Ireland 2020

A recent survey of Europe’s highway infrastructure has concluded that almost half of Europe’s bridges are nearing the end of their design live. Work in the wider Structural Health Monitoring sector is aiming to develop reliable and cost-effective methods for verifying condition, remaining service life and safety of ageing structures. Most bridge condition assessment methods are based on deflection, acceleration or strain measurements. This paper looks at the possibility of using rotation measurements as a main parameter to identify damage. This study looks at numerical analyses of a moving point load on a one-dimensional bridge model to provide ...


A Numerical Analysis Of Stone Masonry Arch Bridges And Structural Backing, Thomas Kerr, Tomás O'Flaherty 2020 Department of Civil Engineering and Construction, Institute of Technology Sligo; National Roads Office, Drumlonagher, Donegal Town, Donegal

A Numerical Analysis Of Stone Masonry Arch Bridges And Structural Backing, Thomas Kerr, Tomás O'Flaherty

Civil Engineering Research in Ireland 2020

Masonry arch bridges are a significant part of the transport network system in Ireland. Therefore, it is essential that we maintain the existing masonry bridge stock as a valuable asset and protect these bridges from a heritage viewpoint. The increased structural demands placed upon these bridges coupled with more sophisticated analysis methods have required and enabled a greater understanding of the response of masonry arch bridges to ever increasing traffic loading. When loaded, the structure acts in compression and the arched configuration enables the transmission of loads through the individual masonry units to the supporting piers or abutments. The stability ...


Probabilistic System Analysis – Practical Examples For Railway Bridges, Lorcan Connolly, Marko Duranovic, Róisín Donnelly 2020 Roughan & O'Donovan Innovative Solutions

Probabilistic System Analysis – Practical Examples For Railway Bridges, Lorcan Connolly, Marko Duranovic, Róisín Donnelly

Civil Engineering Research in Ireland 2020

The issue of maintenance of ageing bridges with insufficient budget allocations is well documented throughout Europe and beyond. To combat the issue of out of date assessment standards, insufficient structural information and deteriorating bridges, probabilistic assessment bridge techniques have evolved significantly over the past number of years. Previously, probabilistic analysis methods have been applied at the element level, where the highest element failure probability is assumed to govern for the structure. This fails to account for inherent redundancy which is often present in bridge structures. For example, the development of a plastic hinge due to elastic failure in a steel ...


Case Study: Calculating Bridge Displacement From Accelerations For Load Assessment Calculations, Andrew Bunce, David Hester, Su Taylor, James Brownjohn, Yan Xu 2020 Civil Engineering, School of Natural and Built Environment, Queens University Belfast,

Case Study: Calculating Bridge Displacement From Accelerations For Load Assessment Calculations, Andrew Bunce, David Hester, Su Taylor, James Brownjohn, Yan Xu

Civil Engineering Research in Ireland 2020

Recovering displacement from accelerations has been demonstrated on bridges previously, with the main challenges being the presence of low frequency noise and the need for user-calibrated filters to overcome this. Therefor this paper presents a case study of a low-cost load test procedure, using bridge acceleration to calculate displacement. Typical approaches look use filtering or signal collecting methods to mitigate noise, however this study uses an aviation grade accelerometer to minimise noise in the acceleration signals and employs a quality control procedure to alert the user to the quality/reliability of the results. A live/open bridge is tested using ...

Towards Automated Uav Assisted Bridge Inspections Using Photogrammetry And Image Processing Techniques, Habeene Habeenzu, Patrick Mcgetrick, David Hester, Su Taylor, Louie Wong

Civil Engineering Research in Ireland 2020

At the heart of addressing bridge condition challenges are bridge inspections. The main activity during a bridge inspection is close, arm’s length visual inspection of the entire bridge structure. During this process, all defects such as cracks, spalls and material degradation are manually recorded on the bridge itself and on inspection forms. Where access is difficult such as where a safe working platform cannot be mounted under bridge decks, or on high bridges, expensive underbridge equipment is required which when used results in expensive lane closures. Furthermore, visual inspections have been shown to lack consistency from inspector to inspector ...
