Behavior of Orthotropic Steel-UHPC Composite Bridge Deck under Cyclic Loading

In recent years, ultra-high performance concrete (UHPC) has been introduced in the design of orthotropic steel decks (OSD) to reduce the risk of fatigue cracking. To investigate the fatigue behaviour and fatigue damage process of the orthotropic steel-UHPC composite bridge deck, a fullscale specimen was designed and tested under cyclic loading....

Shear performance of replaced bolt shear connectors in prefabricated composite beams

Bolt shear connectors have the advantage of efficient installation and demolition when used in prefabricated composite beams. When bolt shear connectors are damaged in the service period and replaced by new ones, the shear performance of replaced bolts is to be affected by the existing structural damage. This paper investigates the shear...

Experimental investigations of welding induced temperature gradients and distortions in a segment of an OSD

Orthotropic bridge decks are susceptible to fatigue cracks which are influenced by the thickness of their components, welding procedure, type of the weld, the position of the considered detail in relation to the local loading condition and by residual stresses due to welding. The above-mentioned parameters determine the detail category for...

Case studies for quantifying the value of structural health monitoring information: Lessons learnt

This paper provides an overview, insights, results and a classification related to development and analyses of case studies within the scientific networking project COST Action TU1402 on the value of Structural Health Monitoring (SHM) information. With an outline of the framework and approaches, a procedure on how to quantify the value of SHM...

Innovative Ways of Dealing with Existing Problems: How to reliably Assess the Cause of Damage of Masonry Structures in an Area with Man-induced Earthquakes?

Groningen, a province in the northern part of the Netherlands, suffers from earthquakes because of gas drilling. The residential building stock in Groningen was not designed for these loads. Over the years a lot of smaller and larger damage has developed, possibly - but not necessarily - caused by the effects of gas drilling. Delft University of...

Innovative system for the construction and management of student residences - Frameup system

Sweden has a strong demand on the construction of student accommodations and consequently significant efforts have been taken to increase and streamline construction methods. In addition, the fluctuation on the number of students admitted at each year, in each university, lead to periods of house shortage or, in opposition to that, to...

Application of Probabilistic Robustness Framework: Risk Assessment of Multi-Storey Buildings under Extreme Loading

Risk assessment is a requirement for robustness design of high consequence class structures, yet very little guidance is offered in practice for performing this type of assessment. This paper demonstrates the application of the probabilistic risk assessment framework arising from COST Action TU0601 to multi-storey buildings subject to extr eme...
