~BLSB

 

~BLSB, p, AssemKL, AssemFE, HL, HLMin

Defines surface loads

SOLUTION: BRIDGE AND CIVIL NON LINEARITIES: Bridge model loads

p

Surface load value.

AssemKL

Assembly name containing keypoints and lines defining the road axis.

AssemFE

Assembly name with nodes and elements over which the loads will be applied.

-          Solid Model: SURF154

-          Shell Model: SURF154

-          Beam model: BEAM3, BEAM4 BEAM44, BEAM54.

HL

The part of the surface load that will be applied as a horizontal load (braking or starting load). It must be ³ 0 or blank (in this case it is taken as zero).

HLMin

Minimum values of the aforementioned loads (for the whole vehicle). It must be ³ 0 or blank (in this case it is taken as zero).

Notes

- A positive surface load will be assigned to a pressure in the normal direction towards inside of the structure.

- If the bridge has been generated with the ~BRGEN command and the variable AssemFE has been left blank, the program will define:

AssemFE = BDECK

- If the ~BRSKTCH command has been used and the variable AssemKL has been left blank, the program will define:

AssemKL = BROUTE

- The ~BLSB command must be included in the definition loop of surface loads, the beginning of which is carried out with the ~BLSST command and ends with the ~BLSEND command.
