Walking-induced vibration control in multifamily timber buildings: Analysis of floor configurations and support conditions using classical vibration theory

Practical combinations of floor configurations and support conditions are studied for the development of a lightweight timber building method that is suitable for multi-family residential buildings. Classical vibration theory forms the base for a methodology that is developed to assess transmittance of vibrations to adjoining floor fields....

Estimating the (remaining) service life of timber bridges with the use of factor methods: And incorporating these methods in the calculation of the total costs of ownership

Timber bridges are much applied structures in the Dutch landscape. In contrast to the other two most common building materials, concrete and steel, the use of timber is however almost exclusively limited to bridges for lighter traffic, e.g. pedestrians and bicycles. Examples of timber traffic bridges in Germany, Scandinavia and even in the...

Retrofitting of Unreinforced Masonry with Timber Elements

Due to gas extraction, seismic activity has become a major problem in the province of Groningen. Existing buildings are not designed to withstand seismic loads and are likely to be structurally unsafe. Two storey terraced houses with concrete floors and large openings in the ground floor façade walls are onsidered vulnerable, since the in-plane...

Long-span Timber Roof Structure for the New Feyenoord Stadium

Timber structures are experiencing a revelation in the build environment due to new technologies and production techniques. However, the longest spans created with timber structures still don't compete with the span widths of structures made of steel. This thesis provides a preliminary design for the long-span football stadium roof structure of...

Strength influencing parameters of iroko glued laminated timber

As timber is being used for several millennia as construction material, glued laminated timber (glulam), a highly engineered timber product, exists for about hundred and fifty years. In Europe, it is nowadays common practise to make glulam from softwood species, though in the last few decades glulam made from different kinds of hardwoods emerged...

Fire Performance of Cross- Laminated Timber: Investigating adhesives, compartment configuration and design guidelines

Cross-Laminated timber (CLT), and other engineered timber products, are under high demand due to their prefabricated nature and environmental benefits. A key concern surrounding the application of CLT in buildings is its combustible nature and subsequent contribution to a compartment fire. Previous research has shown that exposed CLT, under...

The Current State of the St. BavoChurch Tower: A Verification Study and Structural Analysis of the Wooden Tower of the St. Bavo Church in Haarlem,The Netherlands

The structural reliability of the wooden tower of the Grote of St. BavoChurch in Haarlem has been assessed with the regular methods. In addition to the regular methods, some modern technologies have been used in the structural analysis. The mechanical properties of the timber have been determined with longitudinal vibration tests and visual...

Monitoring foundations

It is estimated that about 400.000 houses in the Netherlands – both shallow and wooden pile foundations – could be facing problems with their foundations. Although, house owners are becoming increasingly aware of the fact that problems (and thereby costs) can be prevented if remedial measures are taken in time. Monitoring of the foundation can...

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...
