Timber terraced housing: Assessment of transverse stability

The transverse stability of timber terraced houses can be provided by CLT stability walls where decoupled timber terraced houses are preferred to meet acoustic requirements leading to rather large thicknesses for the CLT stability walls and many large connections for anchorage to the foundation. The main goal of this research was to investigate...

Air Pollution from High-rise Construction in Rotterdam: Comparison of black carbon (BC), ultrafine (UFP)and particulate matter (PM2.5 and PM10) ambient concentrations from conventional and biobased (Cross-Laminated Timber CLT) construction methods

This research addresses the challenge of climate change and air quality, focusing on the construction industry's impact in the Netherlands. The construction sector, a significant source of air pollution, necessitates sustainable practices for mitigating the effects of climate change and reducing pollutants. The study emphasises the need for...

Almere Pampus - A timber city steering towards a nature-inclusive urbanism

Cities are constructed with extractive, finite resources that put enormous pressure on global climatic conditions. The building and construction sector is responsible for 36 percent of the global energy demand and 37 percent of the carbon dioxide emissions worldwide. With the prospect of massive urbanization, the built environment will...

Building a sustainable future: a comparative life cycle assessment of a cross-laminated timber and a lightweight steel frame building

The Netherlands has faced rapidly increasing housing prices over the previous years. As a counter measure, the government is aiming to increase the construction of new houses from around 70 thousand annually to 100 thousand annually, to achieve 900 thousand new houses by 2030. At the same time the world is facing a climate crisis and the...

Sound transmission in cross-laminated timber buildings: A numerical approximation of the sound transmission through CLT elements and junctions

Low-frequency sound transmission in a cross-laminated timber apartment building can result in annoyance, even if the acoustic requirements of the building code are fulfilled. Cross-laminated timber is an upcoming material in the building industry. But there are also problems arising when building with this relatively new material. CLT is a...

Creating a city for a new generation of integration: In which young people with migration background have a sense of belonging

The Netherlands experienced a large influx of refugees over the past years, which peaked in 2015. Many of these refugees have recently had their temporary residency extended into a permanent residency. In spite of this, there is a disproportionately high percentage of unemployment among refugees and many experience a lack of social and academic...

Onbeperkt Wonen: Living independently in a stimulating residential environment for young people with a mild intellectual disability

“In which way can the design of the residential environment contribute to the social self-reliance of young people with a mild intellectual disability?” We are facing a huge challenge in the Netherlands: we have to build up to ‘1 Million Homes’ by 2030. But such a huge assignment raises the question if those new dwellings will be inclusive...

Environmental friendly living: A conscious start for young people in the city

Starters are facing an almost impossible task to find a dwelling on a housing market where there is scarcity. At the same time a changing climate and other environmental issues demand a different way of building, that differs from the traditional building methods and uses materials that have a positive impact to these environmental issues. A...

A Post-tensioned Cross-Laminated Timber core for buildings

This master thesis is on post-tensioning cross-laminated timber stability cores for multiple story buildings. When designing a CLT core, significantly larger core sections will be needed than when designing a stabilizing core in concrete. This is for one part due to the limited stiffness of the CLT compared to concrete. For another part it is...

Integral Design Process of CLT Structures and Robotic Fabrication: An integral workflow for the preliminary structural design of CLT connection panels with the use of customized robotic fabrication

Timber and complex designs are making a move in the building industry, as the building industry is on the brink of a significant change toward a 100% customized, more sustainable architecture. Robotic fabrication and Cross-Laminated Timber (CLT) can play an important role in this change, but there is a lot of uncertainty and ignorance about the...

Self-extinguishment of cross-laminated timber

Cross-laminated timber, or CLT, is receiving attention for its potential application in tall building structures. As a combustible material, one of the main challenges for the construction of these buildings is the fire risk that results from its use in the structure.<br/><br/>Unprotected CLT can burn along with the fuel load present in a...

Hollow Core Cross-Laminated Timber: Optimized for a more efficient use of material

Wood is an important building material that has been used for thousands of years throughout the world. It is the most widely used building material and due to its characteristics suitable for a wide range of applications. Still, for the last century steel and concrete have been the materials of choice for large buildings. Part of the reason for...

Self-extinguishment of cross-laminated timber

Cross-laminated timber, or CLT, is receiving attention for its potential use in tall buildings. As a combustible material, one of the challenges for the construction of these buildings is the fire risk that results from its use in the structure. Unprotected CLT can burn along with the fuel load present in a compartment. Irrespective of its fire...

The structural feasibility of timber wind turbines in the Netherlands

Inspired by the world's first timber tower for a multi-megawatt turbine, an investigation has been carried whether or not this design would be suited for Dutch wind conditions as well. Demands from design codes have been summarized and the frequency behaviour of these timber towers has been studied. Apart from the original softwood Cross...

Self-extinguishment of cross-Laminated timber

Cross-laminated timber, or CLT, is currently receiving attention for its potential use in tall building structures. Timber being a combustible material, one of the main challenges for the construction of these buildings is the potential fire risk that results from its use in the structure. For tall buildings, there is an increased severity of...

Lateral behavior of post-tensioned cross laminated timber walls using finite element analysis

Cross laminated timber (CLT) has been rapidly developed and utilized for multi-rise constructions in recent years, even high-rise CLT buildings with 40 stories have been proposed and designed. A use of unbonded post-tensioning (PT) steel bars through over CLT walls of the high-rise CLT buildings to take up the tensile forces produced by wind...

Necklace for IJsselmeer

This project is a proposal to reactivate rural region, that prospered in the past, by tourism with small architectures. It is difficult to attract people to such area by one special existence. However, there is a possibility to engage the interest of people by invisible ring made by architecture and landscape. The balance of design in the...
