1. 1. Design for Serviceability - A probabilistic approach

   Författare :Daniel Honfi; Avdelningen för Konstruktionsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; design codes; long-term deflections; structural reliability; serviceability;

   Sammanfattning : In many design situations the acceptable performance of structures is defined by serviceability requirements. To estimate the probability of serviceability failure three main design aspects should be considered: (1) the relevant exposures, (2) the structural response and (3) the performance criteria.

3. 2. Vibrations in Lightweight Buildings - Perception and Prediction

   Författare :Juan Negreira; Teknisk akustik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Psycho-vibratory evaluation; Vibrations; Timber floors; Lightweight; Measurements; Serviceability criteria; Vibration annoyance; Vibration acceptability; Elastomer; Finite element method; Prediction Tools.;

   Sammanfattning : When the Swedish construction code (in 1994) allowed wooden multi-storey buildings to be built, this type of lightweight construction became popular due to its low cost and ease of construction, and also because wood is a plentiful resource in Sweden. Drawbacks in such buildings are disturbing vibrations and noise propagating in the construction, especially through junctions. LÄS MER

4. 3. Vibration of Low-Frequency Floors - Dynamic Forces and Response Prediction

   Författare :Per-Erik Eriksson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : This thesis deals with methods for predictive calculations of the vibration response of low-frequency floors, i.e. floors with the lowest natural frequency below 7 to 8 Hz, subjected to pedestrian traffic and other dynamic forces. LÄS MER

5. 4. Development and Evaluation of Mechanical Joints for Composite Floor Elements with Cross Laminated Timber

   Författare :Nicolas Jacquier; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

   Sammanfattning : One of the important issues in the development of a multi-storey timber construction system is the definition of the floor solution. This thesis focuses on the development of composite floor solutions where Cross Laminated Timber (CLT) panels are used as a base element. LÄS MER

7. 5. Subjective assessment of vibrations in lightweight floors

   Författare :Junye Wang; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

   Sammanfattning : Lightweight steel floors arise a lot of attentions because of its advantages, such as cost effective, recyclable, and having a short construction period. On the other hand, low frequency vibrations induced by normal human activities get more and more complains for these types of structures. LÄS MER
