  1. 1. Axially loaded screw joints in wooden structures exposed to fire : Fire tests in furnace and numerical calculations in TASEF of different screw mounting variations

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Henrik Pettersson; Emma Wiklund; [2022]
    Keywords : Fire; wood; screw joints; strength; temperature; TASEF; Brand; trä; skruvförband; bärförmåga; temperatur; TASEF;

    Abstract : To achieve sufficient stability of a structure in a fire scenario, a thorough design of joints in wooden structures are as important as the design of the construction itself. As an earlier study points out, there are no existing design method available to determine the load capacity of an axially loaded screw joint in wooden structures, which complicate the process of a thorough design of the joint in a fire scenario.

  2. 2. Att läsa brandspår i skogslandskapet: olika underlag för att förstå naturlandskapets branddynamik

    University essay from SLU/School for Forest Management

    Author : Anders Dahlberg; [2016]
    Keywords : ASIO; brandspårsfrekvens; skogsbrand;

    Abstract : The purpose of this study is to explore different methods to understand the local history of past fire disturbance regimes in a forest management unit. Focusing on the Bergslagen region in south-central Sweden, which has a very long history of forest management, the frequency of occurrence of fire scars on living trees, burned wood, and macroscopic charcoal in the litter layer and in small peat bogs, were studied in landscape strata different with different biophysical characteristics affecting the probability of fire.

  3. 3. Skalbaggars artsammansättning efter intensiv skogsbrand : en jämförelse mellan artgrupper två år efter brand

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Teresa Leifsdotter; Anna Nilsson; [2015]
    Keywords : specialister; generalister; brandgynnad; rödlistad; funktionella grupper; boreal skog; störning;

    Abstract : Skogsbränder har idag blivit något ovanligt och arter som är beroende av bränder för reproduktion och födotillgång blir därför missgynnade. Idag finns en hypotes om att vissa arter som gynnas av kalhyggesbruk konkurrerar ut brandspecialiserade arter och är en anledning till dessa arters tillbakagång. READ MORE

    Abstract : In this study, the immediate and short term (three months) effects of conservation burning have been investigated in coniferous forests in southeastern Sweden. Five tree species were investigated Picea abies (Norway spruce), Pinus sylvestris (Scots pine), Populus tremula (aspen), Betula pendula (silver birch) and Betula pubescens (downy birch), as well as ground vegetation of mosses, dwarf shrubs and ground lichens.
