Tvångskrafter i betongbroar : analys och implementering av metod för reducering av tvångskrafter
Nowadays concrete structures are often designed with a complex geometry, which demands finite element analysis. A well known problem in relation to finite element analysis is restraining forces, which may be strongly overestimated in linear analyses of concrete structures. Restraint forces are internal forces that are created when a structure is prevented from movement. Restraint forces can for ex
