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 naturresurserAbstract : 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. Thermal human detection for Search & Rescue UAVs
University essay from KTH/Maskinkonstruktion (Inst.)Abstract : Unmanned Aerial Vehicles (UAVs) could play an important role in Search & Rescue (SAR) operations thanks to their ability to cover large, remote, or inaccessible search areas quickly without putting any personnel at risk. As UAVs are becoming autonomous, the problem of identifying humans in a variety of conditions can be solved with computer vision implemented with a thermal camera. READ MORE

3. CHARACTERISATION OF CROSS LAMINATED TIMBER PROPERTIES
University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaperAbstract : This project concerns an analysis of a hitherto untested method for determining the modulus of elasticity (MoE) and shear modulus parallel to grain, as well as the rolling shear modulus of cross laminated timber (CLT) through 3-point bending tests. A review of analytical models and methods is included, followed by an evaluation of the effect of the annual ring orientation and shear stress distribution at shear loading of individual board cross-sections.

4. Pile subjected to lateral load : Analytical hand calculation implemented by programming
University essay from KTH/Byggteknik och designAbstract : The official recommendations in geotechnical engineering are according to Swedish practice to install inclined driven piles in order to resist external horizontal loads, which usually consist of windloads. These loads gets counteracted by utilizing the pile's axial load-bearing capacity, however when designing a foundation the use of inclined piles has proven to be problematic from a number of different perspectives.

5. Design of column bases concerning bending and shear nibs
University essay from KTH/Byggteknik och designAbstract : The purpose of the thesis is to find out how to design column bases with conventional methods presented by European standards and codes, but above all from the Steel Construction Institute's handbook on structural joints and compare it with finite element analyses. However, today there are no good instructions for how column bases exposed to multiaxial bending should be designed, where assumptions based on structural mechanics also was compared with computer tools.
