LOADADD

Bulk Data Entry Defines a static load as a linear combination of load sets defined via FORCE, MOMENT, FORCE1, MOMENT1, PLOAD, PLOAD1, PLOAD2, PLOAD4, RFORCE, DAREA, ACCEL, ACCEL1, ACCEL2, GRAV and LOADADD entries.

The LOAD Bulk Data Entry is also accepted for backward-compatibility and is equivalent to LOADADD.

Comments

  1. The load vector defined is given by:(1)
    P → = S ∑ i S i P → L i
    Where,
    P →
    The static load as a linear combination of the defined load sets
    S
    Scale factor defined in Field 3
    Si
    Scale factors defined in the S1, S2, etc., Sn fields.
    P → L i
    Loads, whose ID's, are referenced by the L1, L2, ..., Ln fields.
  2. All data after the first blank field is ignored.
  3. Load sets must be selected in the Subcase Information section (LOAD=SID) if they are to be applied to the structural model.
  4. A LOADADD entry can reference a set identification number defined by another LOADADD entry. However, two LOADADD entries should not reference each other.
  5. SPCD load SIDs cannot be referenced by LOADADD data.
  6. LOADADD should not share the same ID with other load set Bulk Entries.
  7. This card is represented as a load collector in HyperMesh.
