1. 1. Climate improved concrete structures : Possibilities in design and construction

   University essay from KTH/Betongbyggnad

   Author : Dalia Attia; Steve Kiryakos; [2023]
   Keywords : ;

   Abstract : Concrete is an important material for building a sustainable society, serving as the foundation of modern infrastructure. Concrete’s widespread adoption in both commercial and residential construction projects can be attributed to its exceptional versatility, strength, durability, and long-lasting qualities. READ MORE

3. 2. Investigation of Adsorption and Retention of Charged Compounds In RPLC

   University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

   Author : Emma Fryxelius; [2022]
   Keywords : adsorption; adsorption isotherm; charged compounds; promethazine hydrochloride; propranolol hydrochloride; mixed-mode; retention; RPLC;

   Abstract : The adsorption isotherm of two weak bases, Promethazine hydrochloride and Propranolol hydrochloride, were determined with isocratic reversed-phase liquid chromatography, with a 60 w% methanol in 20 mM sodium acetate buffer pH 4 as the mobile phase, and calculated by the elution by characteristic points method. The data obtained from the method were then fitted into the Langmuir isotherm and the electrostatically modified Langmuir. READ MORE

4. 3. Transverse force absorption in column base mounts for steel columns : Screw joints in column bases

   University essay from KTH/Byggteknik och design

   Author : Dejan Jovanovic; Ruslan Khalilov; [2021]
   Keywords : column bases; transverse force absorption; tightening moment; clamping force; non-prestressed joints; Pelarfötter; tvärkraftskapacitet; åtdragningsmoment; spännkraft; icke förspända förband;

   Abstract : It is common to use different construction materials in combination such as concrete, steel, wood and glass in order to optimize buildings. The purpose of this is to reduce weight and increase load capacity, but it also facilitates assembly and reduces construction time. READ MORE

5. 4. Design of column bases concerning bending and shear nibs

   University essay from KTH/Byggteknik och design

   Author : Rodi Kay; [2021]
   Keywords : Column bases; Pelarfötter;

   Abstract : 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.
