DYNAMIC RESPONSE OF TALL TIMBER BUILDINGS UNDER SERVICE LOAD - RESULTS FROM THE DYNATTB RESEARCH PROGRAM Open
Wind-induced dynamic excitation is a governing design action determining size and shape of modern Tall Timber Buildings (TTBs).The wind actions generate dynamic loading, causing discomfort or annoyance for occupants due to the perceived ho…

NEW CRITERIA FOR VISUAL STRENGTH GRADING OF SAWN TIMBER FROM BIRCH GROWN IN SWEDEN Open
Today there is no standard for strength grading and CE-marking sawn timber of Birch grown in Sweden, which makes it impossible to use this material as structural timber.Internationally, there are standards for visual grading of hardwood in…

EXPERIMENTAL AND NUMERICAL ANALYSES OF A CONNECTION FOR CLT STRUCTURES Open
Although building systems made of cross-laminated timber (CLT) have become common in Sweden in the past 20 years and they have developed rapidly during the same period, steps remain to be taken to simplify the assembly of such systems, esp…

FORCED RESPONSE MEASUREMENTS ON A SEVEN STOREY TIMBER BUILDING IN SWEDEN Open
Forced vibration tests have been conducted on the seven-storey timber building Eken in Mariestad inSweden. The main objective is to estimate the building’s dynamic properties from test data. The eigenfrequencies, modeshapes and their scali…

LOAD LEVELS AND CRITICAL DESIGN ISSUES IN A MULTI-STOREY RESIDENTIAL TIMBER BUILDING BUILT UP BY PREFABRICATED VOLUMETRIC ELEMENTS Open
The use of structural timber in residential buildings has increased considerably in Sweden during the last decade.Concomitantly, there has been an emphasis on augmenting the level of prefabrication for such structures.A simultaneous need f…

Literary socialisation through education. A comparative study of Swedish and French upper secondary school students’ reception of a narrative text Open
Different ways of teaching literature in school are often a result of tradition, cultural heritage, and the underlying assumptions of the motivating reasons for studying literature at all. This paper presents results from a comparative stu…

Modelling local bending stiffness based on fibre orientation in sawn timber Open
Strength of structural timber depends to a high degree on the occurrence of knots and on the local fibre deviation around such defects. Knowledge of local fibre orientation, obtained by laser scanning, has been utilized in a previously dev…

Optimal timing of early genetic selection for sawn timber traits in Picea abies Open
In breeding Norway spruce, selection for improved growth and survival is performed at age 10–15 years in order to optimize genetic gain per year. We investigated whether a selection based on wood traits such as density and grain angle, mea…

Dynamical properties of a large glulam truss for a tall timber building Open
When designing a tall timber building, the accelerations due to wind loads are in many cases decisive. The parameters governing the dynamic behaviour of the building are the structure’s stiffness, damping and mass together with the loads. …
