1. 1. Numerical analysis of a bearing strength in delaminated composite joint

   University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Author : Olavi Kukkonen; [2023]
   Keywords : Bearing strength; Single-lap shear; Delamination; Countersinking; Hole size;

   Abstract : Composite structures are commonly joined using adhesive or mechanical joints, withmechanical joints being preferred when components need to be removable for maintenancepurposes. However, the presence of mechanical joints introduces a discontinuity in theload path, which can serve as an initiation point for failure and needs to be taken intoaccount in the design of the joint.

3. 2. Back analysis of rock mass properties in the regional fault zone under Lake Mälaren

   University essay from KTH/Jord- och bergmekanik

   Author : Jiaqi Liu; [2022]
   Keywords : Rock mass property; back analysis; tunnel deformation; optimization algorithm; numerical analysis; Bergmassans egenskaper; bakåtanalys; tunnleldeformation; optimeringingsalgoritm; numeriska analyser.;

   Abstract : The properties of the surrounding rock mass in underground projects have significant impacts on the design and construction. However, it is quite challenging to evaluate rock mass properties due to the great uncertainties of the geological conditions. READ MORE

4. 3. Evaluation of a testing method for shear stiffness properties for cross laminated timber

   University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

   Author : Calle Lind; [2022]
   Keywords : CLT; cross laminated timber; EN 16351; four-point bending; rolling shear modulus; FE-modelling; Technology and Engineering;

   Abstract : Cross laminated timber (CLT) is an engineered wood product that was first developed in the 1990s. Since then it has grown in popularity thanks to its many advantages such as: low environment impact, high degree of prefabrication and low weight. As the material is relatively new the standardization process is still in the early stages. READ MORE

5. 4. Performance of reinforced concrete bridges strengthened with Carbon Fiber Reinforced Polymers : Case study: Essinge Bridge over Pampaslänken

   University essay from KTH/Bro- och stålbyggnad; KTH/Jord- och bergmekanik

   Author : Zeinab Mirzahassanagha; Eva Malo; [2021]
   Keywords : CFRP; External Strengthening Method; RC Bridges; Curved Substrate; Finite Element Modelling; Kolfiberväv; Extern Förstärkningsmetod; Betongarmerade broar; Konkav yta; Finita Elementa Modellering;

   Abstract : This master thesis deals with the performance of existing reinforced concrete bridges strengthened with externally bonded carbon fibre reinforced polymers (CFRP). One of the main aims of this work is to understand the functionality of such an external strengthening method applied to a concave surface in a heavy concrete structure such as a bridge. READ MORE

6. 5. Numerical simulations of shear reinforced concrete beams subjected to blast loads

   University essay from KTH/Betongbyggnad

   Author : Anton Frank; Andreas Fristedt; [2021]
   Keywords : Numerical simulations; shear reinforcement; blast loads; dynamic shear failure; Numeriska simuleringar; tvärkraftsarmering; luftstötvåg; dynamiskt skjuvbrott;

   Abstract : Historical accidents and experimental investigations have made apparent that blast loaded concrete members are prone to fail in brittle shear rather than a ductile flexure mode. Air blasts from accidental detonations or explosives may cause severe damage to buildings and infrastructure and it is of great importance that load carrying members can withstand the impulse that arise to avoid progressive collapses.
