Parametric design of bridges : Connection between Rhinoceros-Grasshopper and Tekla Structures (English)
Abstract [sv]

I byggbranschen har nya metoder för projektering utvecklats genom införandet av moderna och mer kraftfulla BIM-verktyg. Flera av dagens konstruktioner modelleras enligt tredimensionella principer.Tekla Structures är ett kraftfullt BIM-verktyg som klarar av att hantera både huskonstruktioner och anläggningskonstruktioner. Trots detta kan programmet inte hantera broar med dubbelkrökning på ett effektivt sätt. Projektörer behöver därför utgå från flera program för att kunna hantera komplexa brokonstruktioner.För att kunna utnyttja fördelar med Tekla Structures, behöver programmet att utvecklas eller kompletteras med andra tredjepartsprogram. Detta projekt syftar till att integrera nya arbetssätt och införa en metodik, i form av parametriserade modellering i Tekla Structures. En sådan form av modellering tillåter användaren att modifiera parametrar för en önskad modell.Ett skript är skapad genom ett visuellt programmeringstillägg, som genererar parametriskbaserade bromodeller. Brokonstruktionstyp som modellerades i detta projekt är en plattrambro.Resultatet av projektet pekar mot att parametriserad modellering är ett effektivt sätt att modellera och en lösning för att bland annat hantera broar med dubbelkrökningar.

Abstract [en]

New methods for project designing in the building construction industry have been developed by introducing modern and powerful BIM tools. Several of today’s constructions are designed according to three-dimensional principles.Tekla Structures is a powerful BIM tool that is capable of managing both house and infrastructure constructions. Despite this, the program cannot handle bridges with a horizontal and vertical curvature efficiently. The designers must instead rely on several other applications to manage complex bridge constructions.In order to use the advantages of Tekla Structures, the software needs to be evolved or complimented by other third party softwares. This project aims to integrate new working technics and introduce a method based on parametric design in Tekla Structures. Such form of modeling enables the modification of parameters to a desired model for the user.A script is created through a visual programming extension that generates a parametric based bridge models. The bridge type in this project was designed, is an integral bridge.The project has proved that parametric based design is more effectively and a solution to manage bridges with horizontal and vertical curvature.
