1. Seismic Response of Connection Details in Traditional Groningen Houses
Onur Arslan PhD Candidate, TU Delft
Introduction
The Groningen gas field, in the north-eastern part of the Netherlands, is the largest gas field in Western Europe. The field was discovered in 1959 with drilling of the Slochteren-1 well.
Induced seismicity of the Groningen gas field is caused by the production of gas. Since 1986, seismic events have been recorded in the northern part of the Netherlands, which is thought to be a tectonically inactive region. Seismicity in the north of the Netherlands, ranging in Magnitude from ML 0.8 to ML 3.6, has occurred over various small gas fields and is considered to have been induced by gas production.
Starting in 2003, the number of events and magnitudes started to increase. In 2012, the largest event (ML 3.6) occurred, which caused the most damage to date and in the second largest event (ML 3.4) occurred in the beginning of 2018.

Experiment
Experiment is focused on the definition of the complete load-deflection behaviour of each considered connection; the tests aim at identifying stiffness, strength, ductility, and dissipative behaviour of the connections.
The tests will involve monotonic and cyclic loading protocols to be able to define the load and displacement response of the connection reversal loads, such as earthquakes, as well as the development of failure mechanisms under such loading cases. Also, dynamic tests will be performed.
Conclusions
Numerical models will be created and calibrated versus the experimental findings. Characteristic hysteretic behaviours of the examined connection types will be provided for the use of engineers and researchers.
