Vertical displacements in a multi-story building with load bearing timber frame structure (English)
Abstract [sv]

Arbetet är ett förberedande underlag inför Linnéuniversitetets experiment på ett planerat flerbostadshus på Torparängen i Växjö. Under experimentet ska klimatförändringar som fukt och tempratur i och runt konstruktionen beaktas för att studera dess inverkan på vertikalförskjutningar i konstruktionen. Arbetet beskriver och motiverar placering av de sensorer som mäter klimatändringarna och vertikalförskjutningarna. Även teoretiska beräkningar av de vertikalförskjutningar huset kommer utsättas för redovisas

Abstract [en]

Wood is a recyclable building material and a natural supply. Building in wood is environmentally friendly and is becoming increasingly demanding. But building high structures in wood has its difficulties. That wood becomes deformed by both loadstrain and moisture variation is one of these difficulties. This report is a basis for the experiments that Linnaeus University is going to perform to study these deformations, so called vertical displacements. At Torparängen in Växjö, Derome will build a number of multi-story residential buildings of modules with load-bearing wooden frames. At the highest of these houses, data for temperature, relative humidity, moisture content and vertical displacements in and around the house's body will be collected using sensors. The sensors will be placed in the construction during the erection of the building. Based on previous experiments in the field, preparations for placement of the sensors have been made and motivated. A theoretical calculation of vertical displacement was also made. This in order to later compare the theory with reality. The main conclusion of the work was to minimize the proportion of wood loaded perpendicular to the fibers. Because it is the weakest part in the construction for vertical displacements. Furthermore, it was concluded that moisture content variation in the wood is the main reason for the total vertical deformations.
