Thisrequireseffectivecoordinationbetweenthetwodisciplines and without the right tools problems often arise. The thesis was done by support from structural engineers at Tyréns and in collaboration with a student from the department of architecture. The aim of the thesis was to investigate if the use of parametricdesigntoolsfrombotharchitectsandstructuralengineerscouldbeawayofmakingthe designprocessmoreeffective. Thisthesisalsoincludetestthestructuralplug-insoftheparametric design tools and compare them with the outputs from traditional structural software and hand calculations. The comparison was made for different cases followed by a collaboration project. The cases was targeting different structural features which in turn gave the knowledge needed to develop the collaboration project. The case studies consists of five cases where the first two gives an introduction to parametric modelling. The third case is a steel beam with fully restrained supports loaded by two point loads. It will compare the displacement calculations between the different software. The next case is a concrete slab with different supports along edges loaded by a uniformly load. The analysis includes calculation and evaluation of section forces. The final case is a concrete dome. It is built upbyarchesandfivesupports. Theanalysisofthiscaseincludescalculationandevaluationofthe displacement. The collaboration project is a concrete structure built up by a curved surface lifted by curved columns. The architect worked with the structure in parallel to this this thesis and targeted the development process whilst the authors targeted the structural parts and at the same time gave structural insight to the architect. The results show a difference between the parametric structural tools and the traditional FE software regarding deformation and moments. The hand calculations in the collaboration project show that the amount of reinforcement will not work with the given inputs and assumptions due to practical reasons regarding spacing. The possibility to export models from the parametric environment to traditional engineering soft- ware’s enables a faster analysis, since the modelling capabilities is limited and time-consuming in these. The structural capabilities of the parametric tools are good enough for deciding initial geometry and properties but these will probably change when subjected to an more extensive analysis. iii Sammanfattning De Arkitektoniska och strukturella designprocesserna är nära sammankopplade men traditionellt gjort i två separata steg i byggprocessen. Detta kräver en effektiv samordning mellan de två disciplinerna och utan de rätta verktygen uppstår ofta problem. Uppsatsen genomfördes med stöd från konstruktörer på Tyréns och i samarbete med en student från institutionen för arkitektur. Syftet med uppsatsen var att undersöka om användningen av parametriska designverktyg från både arkitekter och konstruktörer kan vara ett sätt att göra de- signprocessenmereffektiv. Dennauppsatstestadeocksådestrukturellaplug-intilldeparametriska designverktygen och jämförde resultatet med traditionella finita element- och handberäkningar. Jämförelsen gjordes för olika fall följt av ett samarbetsprojekt. Fallen riktade in sig på olika strukturella egenskaper som gav den kunskap som behövdes för att utveckla samarbetsprojektet. Fallstudierna består av fem fall där de två första ger en introduktion till parametrisk modellering. Det tredje fallet är en fast inspänd stålbalk belastad med två punktlaster. Fallet kommer att jämföra deformationsberäkningen mellan de olika programvarorna. Det fjärde fallet är en betong- platta med olika stödvillkor längs kanterna belastad av en jämt utbredd last.

We express our deepest gratitude to our supervisor, Adjunct Prof. Mikael Hallgren for the opportunity to work with this thesis as well as his advice and guidance. We also thank our examiner Professor Anders Ansell for all he has learned us about con- crete structures during our years at the Royal institute of Technology. Furthermore, we thank Tyréns AB for their warm welcome and for an inspiring work environment. Last but not least, we thank Ulf Edgren at the Department of Architecture for the collaboration and sharing his knowledge of architecture and parametric design.
