Development of a re-mountable timber car park

This Master Thesis research is carried out to investigate the most efficient re-mountable timber car park in terms of feasibility and structural performance. Applying the re-mountability principle with a sustainable material like timber is important to help the construction industry tackle environmental problems like global warming. Specifically...

Feasibility of Circular Bio-based Unitised Facade Systems

This thesis project proposes the introduction of bio-based materials in the design of unitised curtain wall façade systems. The work investigates a circular bio-based unitised façade design to understand its feasibility regarding thermal, technical, and environmental performance. The research is divided in four phases, including the material,...

Utilizing crosswise self-growing connection as load-bearing element in building design

Within the context of utilizing alternative materials to promote sustainable construction in the building industry, Living Architecture is a concept that uses living organisms as the building materials. As a rather unconventional approach, it possesses benefits such as low cost, not requiring considerable workforce or industrial material, carbon...

Strength classification of Okan from Gabon by the combination of visual and machining grading

Timber as a renewable source has been extensively applied among European countries in the construction field. Among more than 1000 available wood species which could be potentially applied as engineered wood, tropical hardwood takes up a significant portion and has advantages of high mechanical resistance and remarkable biological durability...

Timber Creep of Historic Urban Quay Walls: The influence of timber creep on the assessment of inner-city quay walls

Amsterdam and many other cities consist of a network of old quay walls, which sometimes have been constructed over a century ago. A large uncertainty exists concerning the current safety of these quay walls and their remaining service lifetime. In the current framework for the assessment of old urban quay walls, the influence of timber creep in...

W/C ratio estimation of concrete through optical microscopy, electron microscopy and thermogravimetric analysis

W/C is a fundamental parameter for concrete mix design, it defines the properties in the fresh and hardened state as well as the durability of the material. Nevertheless, once the concrete has hardened, it is very difficult to estimate the W/C in the original mix design, so far only 2 methodologies has been accepted as a standards. Because of...

Density determination of tropical hardwoods with the Resistograph

This research focused on the question whether it is possible to predict the density of tropical hardwoods with acceptable accuracy based on drill resistance measurements. To assess the feasibility, the influence of the characteristics of the drill resistance measurement tool; the Resistograph® and the wood species have been investigated. With...
