Advanced load system

An advanced load system is defined by means of the following parameters:

• given number of load groups,

• type of load group, e.g. loading block consisting of a given number of concentrated load impulses characterised by the fixed mutual distance, size and position related to the reference point,

• percentage of unloading (in the program called percentage ordinates) that is used if a part of the group of concentrated load impulses is positioned on the negative part of the influence line in such a way that the effect of this part on the invoked maximum was changed,

• for several load groups:

• • for the system with more than two load groups, a constant distance between individual groups,

  • for the system of two load groups, the maximal and minimal permissible distance (variable distance),

• the value of distributed load,

• the value of distributed load between two positive parts of the influence line (similar effect as the percentage of unloading – described above)

• in case of one load group it is possible to change the size of the distributed load around the concentrated load impulse between two specified coordinates: the beginning and end of the change of the distributed load.

The coordinates of concentrated loads that define the position of the load group are defined from a reference point.
