Bridge Loading -Measurement and Modelling
Loading is the most variable term in the structural reliability problem. Since resistance modelling is fairly well understood, in the assessment of existing bridges in particular, the accurate estimation of loading can obviate or reduce the need for replacement and rehabilitation measures, potentially offering bridge owners (and society) enormous savings. Continuiiung on from the success of this mini-symposium at IABMAS 2014, this mini-symposium will examine all forms of loading for pedestrian, highway, and railway bridges, including, but not limited to, long-and short-span bridges, vehicle and traffic modellingand measurements, dynamics, statistical analysis, earthquakes, pedestrians and non-linear modelling methods. Those involved in the measurement and modelling of loading, both static and dynamic and the calibration of theoretical models, are particularly encouraged to submit their work for presentation in this mini-symposium.
Novel techniques regarding the assessment and monitoring of bridges
Assessment and monitoring concepts for bridges become more and more important in the intervention planning (e.g., maintenance, repair, rehabilitation, replacement) for new and existing bridges. Nevertheless, there is still a strong demand for the development and efficient use of novel techniques for monitoring and assessment of bridges. These techniques affect intervention and maintenance strategies and in consequence cost optimization concepts. Therefore, the objective of this Mini-symposium is to highlight the recent developments in science and practice and to formulate the next necessary steps. This Mini-symposium provides the opportunity to disseminate and discuss novel techniques regarding assessment, monitoring and maintenance techniques of bridges.
Submerged Floating Tunnel and Research Progress
The Submerged Floating Tunnel (SFT) is an innovativeand great potential traffic structure for crossing long waterways and deep straits. At current, the design and construction technology of SFT has attracted great attention and special research from scientists and engineers in Italy, China, Korea and Norway etc. The aim of Mini-symposia(MS) on SFT is to share the new research results and ideals in the field, discuss some of Issues related to SFTs, and explore the application prospect of SFT. MS will focus on:
A: Design, analysis, constructionand maintenancemethod of SFT
B: Safety monitoring andriskcontrol of SFT
C: HPPC and composite material and application of SFT
D: Multi-disaster prevention and mitigation of SFT
Prolonging the life of steel and steel composite bridges
The traffic density is growing during the last decades. As a consequence numerous new roads and railwaylines were built or are planned to be realized in the near future. On the other hand existing bridges mustcarry the increased traffic. Most of these bridges were not originally designed for the high service loads and the amount of traffic of today. Many of the structures are aged and, depending on the maintenance andrepair carried out, do not longer suit the purpose. Refurbishment and strengthening is required. According to statistics short span bridges are the most frequent category. This MS deals with results of a recent research project on the framework of RFCS (EU Commission) called PROLIFE focusing on determination of bridge condition through the measurements(monitoring) and structural assessment carried out for innovative solutions and improved methods for repair and strengthening especially of beam and truss steel bridges. The methods are mostly based on a stepwise evaluation with increasing effort in basic data collectionand recalculation if the higher level of accuracy is required. The solutions to update and retrofit existing bridges will be presented and deepen with lectures of this MS. This MS is reserved for partecipants of Prolife project.
