Load - LC

The frame "Load – LC" serves to specify individual loading cases (construction, service) and the loading caused by the bridge and approach slab. Verification and dimensioning analyses of the whole bridge abutment or only its part are carried out according to the specified type of LC.

When using analysis according to EN1997 or LRFD, input forces from bridge and plate are not INCREASED by any partial factors. Forces must be entered as design in accordance with standards EN 1990, EN 1991.

No load specified in the case of construction state and the abutment is verified in a given stage of construction without a closure wall and bridge wings. 

In the case of service state the abutment is loaded by the bridge and approach slab, the whole abutment is verified. 

For abutment verification it appears advantageous to exploit the stage of construction and specify in individual stages different load cases (e.g. construction state, service state without live load, service state with all loads). Individual stages then allow inputting different loads, surcharges, terrain shapes, type of pressure analysis (active, at rest), design coefficients, etc.
