Optimering av böjarmering genom FEM-analys & Strut-and-Tie-modellering

Ett koordinerat samarbete och tydlig kommunikation utgör grunden för en välfungerande projektering av ett byggprojekt. I det traditionella tillvägagångssättet utförs arbetet sekventiellt, där projektet passerar mellan de inblandade parterna i turordning. Detta linjära arbetsflöde leder ofta till fragmentering av projektdata och svårigheter att bibehålla en gemensam förståelse mellan inblandade parA coordinated collaboration and clear communication forms the foundation for a well-functioning construction project. In the traditional approach, the work is carried out sequentially, where the project is passed on from one involved party to the next. This linear work flow often leads to fragmentation of work data and difficulties in maintaining a common understanding of the project, which in tur

Humpback whale (Megaptera novaeangliae) location in Southeast Alaska : modeling the influence of mesoscale krill (Euphausiacea) patch depth and size

Humpback whales (Megaptera novaeangliae) require dense prey aggregations due to the high energetic cost of their feeding methods. Modeling studies have shown that when whales are on their feeding grounds, they are closely associated with high prey concentrations. These studies collapse the prey field into a two dimensional measure of prey abundance in horizontal space. However, patchiness is one o

The Sidelined Cross-Cutting Issue: Mainstreaming Environment into the Water, Sanitation, and Hygiene (WASH) Cluster

Energiutvärdering av slitsade stålreglar i utfackningsväggar

Det ställs allt högre krav från myndigheter på våra byggnaders energi-förbrukning, vilket innebär att marginalerna mellan verklighet och beräkning blir mer betydande. Många parametrar är svåra att påverka, så som brukarvanor, men en av de parametrar som går att påverka är uppbyggnaden av väggen och därav konstruktionens U-värde. Idag finns det standardiserade beräkningsmetoder för träregelkonstruk
