Virtual portfolios for earthquake insurance related risk simulations
(2018-04-05)
Seismic Risk, a combination of Hazard, Vulnerability and Loss, is becoming a mainstream topic due to an increase in the losses and damage caused by earthquake related effects worldwide.
Therefore, it has become an important aspect for insurer and reinsurers since it is extremely difficult to assess due to the lack of the necessary data compared, for example, to car insurance (chapter 1). As described in chapter 2, where the state of the art of seismic risk assessment and simulation is described alongside a more ...

Large Numerical Models in Continuous Hybrid Simulation
(2016-10-20)
Hybrid simulation is a technique that combines experimental and numerical testing and has been used for the last decades in the fields of aerospace, civil and mechanical engineering. During this time, most of the research has focused on developing algorithms and the necessary technology, including but not limited to, error minimisation techniques, phase lag compensation and faster hydraulic cylinders. However, one of the main shortcomings in hybrid simulation that has pre- vented its widespread use is the size of the ...

Generic Finite Element Model for Mechanically Consistent Scaling of Composite Beam-to-column Joint with Welded Connection
(2013-06-26)
To study the behaviour of beam-to-column composite connection more sophisticated finite element models is required, since component model has some severe limitations. In this research a generic finite element model for composite beam-to-column joint with welded connections is developed using current state of the art local modelling. Applying mechanically consistent scaling method, it can provide the constitutive relationship for a plane rectangular macro element with beam-type boundaries. Then, this defined macro ...
