LOADADD

Bulk Data Entry

LOADADD – Static Load Combination (Superposition)

Description

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

Field	Contents
SID	Load set identification number. (Integer > 0)
S	Scale factor (See comment 1). (Real)
Si	Scale factors (See comment 1). (Real)
Li	Load set identification numbers defined via entry typed enumerated above. The load set identification numbers (Li) must be unique. (Integer > 0)

1.	The load vector defined is given by:

Where,

is the static load as a linear combination of the defined load sets.

S is the scale factor defined in Field 3.

are the scale factors defined in the S1, S2, …, Sn fields.

are the 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 may not reference a set identification number defined by another LOADADD entry.

5.	SPCD load SIDs cannot be referenced by LOADADD data.

6.	This card is represented as a loadcollector in HyperMesh.
