The increased seismicity due to the exploitation of natural gas in the Groningen region has put many residential buildings in the region at risk of sustaining seismic induced damages. This has prompted many studies on the seismic behavior of the residential buildings, particularly the ones built from unreinforced masonry (URM). One experimental...

When a breakwater is under heavy wave attack, the concrete armour units will occasionally move, causing a collision between two concrete armour units. This process is called rocking, and induces stresses in the concrete, that may lead to breakage of the concrete armour units. This MSc Thesis provides a probabilistic method to predict breakage of...

In the last decade, maintenance and adaptive reuse, of the existing building stock, have gained ground in the construction sector. For the adaptive reuse of a building, it is required to analyze, meticulously, the existing structure. Unreinforced masonry structures are indicative of the Dutch built environment. For the assessment of their...

In the past decades, gas productions in the province of Groningen in The Netherlands have caused a significant amount of shallow human-induced earthquakes. Its building stock has shown to be highly vulnerable to these unexpected events. Among various building typologies, damage has been reported for approximately 12.9% of the churches in...

This thesis describes the creation of the Equivalent Shear Masonry Model (ESMM). This is an orthotropic material model for low bond strength masonry that uses a smeared cracking approach. It was developed as an improvement of the Engineering Masonry Model (EMM) and adopts that model’s constitutive relations for the behaviour normal to the bed...

An explosion event, having a low probability of occurrence but severe consequences, due to a possible structural collapse, is a so-called "Low Probability and High Consequences (LP-HC)" event[13]. Due to the severe consequences, blast puts a great threat to public security. Thus, civil engineers should take these extreme cases into consideration...

Old bridges in the Netherlands are reassessed to prove their structural safety because of the increased traffic loads. The Eurocode model for the shear capacity of prestressed concrete beams with sufficient shear reinforcement was found to be very conservative for small amounts of transverse reinforcement, which is typical for old bridges. Code...

The demand for sustainable high-rise buildings is growing. Such sustainable high-rise could be realized by the use of mass timber for the structural design instead of more conventional building materials such as steel and concrete. Timber is a renewable resource which can be CO<sub>2</sub> neutral if reforestation takes place to close its carbon...

Swart, Wouter (author)
The numerical simulation of brittle failure with nonlinear finite element analysis (NLFEA) remains a challenge due to robustness issues. These problems are attributed to the softening material behaviour and the iterative nature of the Newton-Raphson type methods used in NLFEA. However, robust numerical simulations become increasingly important,...

This thesis research focusses on the development of a reliable and efficient 3D calculation model of an existing high-rise, reinforced concrete building in the Groningen area, in order to analyse the dynamic behaviour of the existing and subsequently retrofitted main bearing structure of this high-rise building. The assessment of the existing...

The present thesis has the objective to create a procedure for the automatic preliminary design of reinforced concrete structures, based on the Evolutionary Structural Optimization method (ESO). The developed algorithm performs heuristic topology optimization based on multiple criteria, in subsequent optimization cycles executed in series. In...

de Jong, Justin (author)
Probability calculations are used to determine the possible failure of civil structures which includes bridges. The Eurocode uses a conservative form of these probability calculations and this could have a negative economic impact. Having said this, more advanced probability calculation methods are developed to decrease the negative economic...

Verbrugge, Marnix (author)
This thesis is a study towards in-plane behaviour of masonry shear walls modelled through a predefined crack pattern at macro level. The Semi-Lumped method, proposed by Messali (2015), is analysed in detail to confirm the consequences of the SLM assumptions. This is achieved via literature and numerical validations. The final part of the thesis...

The complex mechanical behaviour of timber makes it hard to predict the failure modes in connections made of timber in Finite Element Models (FEM). The combination of various failure modes (brittle and ductile) , anisotropic behaviour, contact of steel elements and large deformations that can occur in a timber joint challenges the use of FEM. To...
