DESCRIPTION:

Global joint masses from the MEMBER ADDED INERTIA command are computed

incorrectly for plane frame members under the following conditions:

1. Member properties are defined as variable with 3 or more segments.

2. The segment cross section properties are defined by AX, IY or IZ

section property values only.

Workaround:

Use space frame members, or in the case of plane frame members, specify

section property values for AX, IX, IY, IZ as a minimum.

DESCRIPTION:

Response spectrum analysis may abort if joint constraints (joint ties/rigid

body elements) having slave releases are present in the model.

Workaround:

If an abort does occur, the use of very stiff, massless members or elements

often may be successfully used as a substitute for joint ties and rigid

body elements.

DESCRIPTION:

If you specify a finite element with incidences but without element

properties or material properties, an abort will occur during any analysis

that you perform (STIFFNESS, DYNAMIC, NONLINEAR).

Workaround:

Specify the element properties and material properties for all elements.

If you go into the Scope Environment, you will get a message indicating

that element properties have not been given. If you go into GTMenu, you

will be told that default element gills are being assumed.

DESCRIPTION:

Transient analysis using direct integration (DYNAMIC ANALYSIS PHYSICAL)

aborts if the analysis problem is described by the direct input of the

stiffness and mass matrices and also includes the input of the damping

matrix. The transient analysis executes successfully if a damping matrix

is not input. An example of the command input for such a problem is shown

as follows:
