The construction of influence lines with a mechanical interferometer

Sword, James Howard 16 February 2010 (has links)
The experimental investigation of the application of mechanical interferometry to the construction of influence lines has proven successful. The method is similar in principle to other methods of model analysis. Mechanical interferometry offers the advantages of speed and permanence of record over the other methods in present use. The idea seems to offer commercial possibilities. / Master of Science

Automatiserad projektering av gång- och cykelbro- med parameterstyrd dimensionering via Grasshopper / Design Automation of Pedestrial Bridge - Using Parametric Design through Grasshopper

Fintling, Nils, Ling, Johan January 2018 (has links)
En projekteringsprocess av en konstruktion kan ofta delas in i två delar, dimensionering ochprojektering. Dimensioneringen utförs enligt för konstruktionen gällande normkrav ochprojekteringen följer sina egna normer samt den dimensionering som är utförd.Även om 2D-projektering fortfarande är vanligt förekommande i projekteringen har BIMmodelleringblivit allt vanligare och värdet av att lagra information i en modell ses alltmersom en nytta i ett projekt.BIM-modelleringen bygger på parameterstyrning av objekt och egentligen finns inga gränserför vilka parametrar som ska ingå i ett objekt.En av de senaste utvecklingarna i projekteringsprocessen är den visuella programmeringensom ger användare möjlighet att styra parametrar till en BIM-modell med hjälp av ett visuelltskript kopplat till BIM-modelleringsverktyget.Det här arbetet syftar på att visa hur ett skript kan driva modelleringen med hjälp avprojektspecifika indata genom att dimensionering av objekt integreras i programmeringen.Med hjälp av programmeringen kan även dimensioneringen redovisas i en annanprogramvara.Resultatet visar att det är fullt möjligt att skapa en modell med hjälp av objektspecifika indataoch att parametrar kan styras med integrerad dimensionering i ett skript skapat med visuellprogrammering. / A design process of a construction can often be divided into two parts, structural design anddrawing. The structural design is made with current standard requirements for theconstruction while the drawing has its own standard requirements along with the results fromthe dimensioning to follow.Even if 2D- drawing still is common in design of a project, BIM-modelling has become morefrequently used and the value of storing information in a model is see more and more as abenefit in a project.The BIM-modelling is based on parametric design of objects and there are actually no limitsto which parameters that should be a part of an object.One of the most recent developments in the design process is the visual programming whichgives users the opportunity to guide parameters in a BIM-model through a visual scriptconnected to the BIM-modelling tool.This work is aiming to show how a script can push the modelling by using project specificinput and perform structural design of load bearing members integrated in the script. With theuse of the script, results can also be verified in another software.Result is showing that it is possible to create a structurally designed model by using only afew object specific inputs and that parameters can be controlled in a script made with visualprogramming.

Předpjatý komorový most / Prestressed box girder bridge

Štíchová, Kateřina Unknown Date (has links)
The subject of this diploma thesis is the design of a load–bearing structure, whitch is situated in the extravillain between the town of Chomutov and the village Křimov. Main purpose of this structure is to pass a roadway I/7 across the valley. There are three options of design and one of them – the prestressed box girder bridge with slanted walls is chosen for more detailed elaboration. The major load–bearing structure is five–span with lenghts 46.50 + 58.00 + 58.00 + 58.00 + 46.50 m, made of post–tensioned nad cast–in–place concrete. The total lenght of load–bearing structure is 269.00 m and the width of load–bearing structure is 13.50 m, the bridge is straight in plan. The structure is analyzed by several computational models, which are designed in Scia Engineer 20.0 software. The structure is analysed in longitudinal and cross directions. The assessments of load state limit and usability limit state are made according to valid standards. This thesis also included time dependent analysis (TDA), that takes construction stage analysis into account.
