Invloedslijnenberekening voor klap van een brugkraan met twee hangstangen: een
Report 94.3.TT.4370, Transport Engineering and Logistics.
This rapport deals with the development of a program in the computer language
MATLAB. This is specifically applied to a statical undefined problem which
appears when an apron of the bridge unloader is suspended by two tension
rods. The construction is laoded with its own mass and with a prescribed
displacement of the support of one of the tension rods. This prescribed
displacement varies in steps from a defined minimum to a defined maximum.
The developed program calculates, for a number af positions of the prescribed
displacement, the bending moment in the crane girder at a specified location,
the normal forces in the tension rods and the reaction forces.
First the model and the theory is discussed in this rapport. After that a
description of the program and a proof on the correctness of the calculation
are presented. Then, in short, the results are analysed.
