Assessment of consequence class two (CC2) buildings: Exploration to an effective and efficient assessment method for existing consequence class two buildings

Numerous structural failure incidents have occurred in the past years. It was found that current methods, such as NEN 2767, fall short in guaranteeing the structural safety of existing buildings. Although structural failure incidents infrequently result in casualties, there are also social and economic consequences that impact both building user...

Sustainable structural timber floors: The influence of vibrational performance on the sustainability of structural timber floors

The recent developments in the building industry to build more sustainable should result in the use of light constructions with a low environmental impact. Timber is a suitable material for this purpose. To reduce the environmental impact of a building, an improvement in an often used structural element can have a significant impact on the...

A design approach to implement reuse of existing concrete bridge girders

To stop the depletion of natural resources, reduce climate change and fight biodiversity loss a circular economy in 2050 is pursued. In the upcoming years a challenging opportunity arises. Many existing bridges and viaducts with bridge decks consisting of prefabricated concrete girders have to be replaced. These girders although not designed...

Vertical Extension of Council Estates: An effective method to optimize timber top-up designs, considering structural limits and environmental impact

The challenge of global warming is an increasing concern of the 21st century. The concept of sustainability is therefore considered of high importance. A major problem of the Dutch government is the growing housing demand. Also after the WWII, the Netherlands faced a housing crisis, resulting in about 847,000 council houses. The massive number...

Het effect van ontwerpmaatregelen bij trein-geïnduceerde trillingen in woongebouwen

Dit onderzoek richt zich op het verminderen van trillingshinder in CLT- en betongebouwen, zodat ze voldoen aan de richtlijnen en er meer naast het spoor gebouwd kan worden. De centrale vraag van het onderzoek is hoe specifieke ontwerpmaatregelen kunnen leiden tot een vermindering van trillingshinder in overeenstemming met de richtlijnen. Een...

Data-Driven Decision-Making for Circular Building Design: Development of an automated decision-support framework for an improved circular design workflow

The transition to a circular economy requires reducing waste and rework in construction projects. Thereby, the evaluation of building circularity in the early design phase is of great importance. However, due to the current design workflow, such practice is hindered because there is not enough information to evaluate building circularity in...

Balancing design and circularity: Optimizing the reuse of steel elements in the design of frame structures

The steel sector is responsible for 4-5% of the total greenhouse gas emissions in the world. Reusing structural steel elements can potentially decrease the need for the production of new steel. However, designing a load-bearing structure with reusable elements poses challenges to the design process. The starting point of the process is different...

Circular floor system for residential buildings: Development of a post-tensioned and modular floor system applicable as a stoery floor in ground-based housing units and apartment buildings

Sustained economic growth based on a linear production model is not feasible on a planet with finite resources and a limited capacity to absorb wastes. By 2050, the world's population has grown exponentially to 9.7 billion and a tripling of the global use of materials can be realistically expected. Therefore, the transition towards a circular...

Reclaim and reuse potential of load-bearing components of se school buildings: Research into the criteria to define the reclaim and reuse potential of load-bearing components of SE school buildings in the Netherlands at an early stage

Global awareness has arisen for sustainable development to reduce the burden of the building sector on the earth’s ecosystems. One of these sustainable developments is the transition towards a 100% circular building economy with high-quality reuse. However, the sector has insufficient knowledge and understanding about the possibilities and...

Factory in a Digital Model: Encoding a timber framed façade panel manufacturing knowledge to improve its design process

Façades within the building industry ore one the most important and expensive aspect of a project. They are the outer skin of a structure and are responsible for improving energy efficiency, while being both innovative and attractive. At the same time, façades need to accommodate requirements to withstand the outdoor environmental conditions. ...

Development of a modular system for circular timber highway bridges

The infrastructure industry currently deals with two issues: the deterioration of (highway) bridges, and the urge to reduce emissions by the construction sector. Rijkswaterstaat must repair or replace hundreds of bridges in the upcoming decades. At the same time, the impact of human behaviour on climate change becomes more visible and must be...

Development of a building adaptability indicator to encourage designing adaptable high-rise buildings: A study to the development of a building adaptability measurement tool

Policy makers have set the goal to reach a completelycircular economy by the year 2050 in the Netherlands. This means that theconstruction industry should shift from its current ‘take-make-waste’ approachtowards a circular approach. The number of buildings of more than 100 m inheight are increasing in the Netherlands, due to...

Improving fall from height risk reduction: Creating a safer construction site with the use of BIM technology

Innovative solutions for safety and risk management on construction sites are required to reduce the amount of accidents that occur globally, as too many occupational accidents still happen in the Architecture, Engineering and Construction industry. A particular problem is the fall from height (FFH) accidents on construction sites, due to...

Timber Upward Extension: Exploration of the use of parametric modelling and machine learning for initial building extension design

The concept of sustainability takes into account a problem of urbanisation which causes a phenomenon of urban sprawl. In order to fight it, the strategy of urban densification is introduced and building upward extensions is one of the methods. However, investigating the feasibility of placing an extension on top requires a significant amount of...

Detaillering langsnaden van breedplaatvloeren met vierzijdige krachtsafdracht bij nieuwbouw: Een onderzoek naar de methodes die door verschillende partijen in de bouw op dit moment worden toegepast in de detaillering van plaatnaden in breedplaatvloeren onder invloed van een positief moment bij nieuwbouw en hoe deze methodes onderbouwd worden.

Uit onderzoek naar de ingestorte parkeergarage bij Eindhoven Airport in 2017 blijkt dat het tot die tijd gebruikelijke detail voor voegen in breedplaatvloeren met krachtsafdracht in twee richtingen onder invloed van een positief buigend moment niet goed werd ontworpen en uitgevoerd. Een breedplaatvloer is in eerste instantie bedoeld om een...
