T2D2S

2D Linear Truss Using Section

• Number of Nodes: 2
• Number of DoFs: 2 (Translation, Translation)

Syntax

element T2D2S (1) (2) (3) (4) [6] [7] [8]
# (1) int, unique element tag
# (2) int, node i
# (3) int, node j
# (4) int, section tag
# [5] bool string, nonlinear geometry switch, default: false
# [6] bool string, if to use log strain, default: false

Remarks

1. Compared to T2D2 , T2D2S use section instead of material. Hence, sectional area is handled by the corresponding section model.
2. The nonlinearity cannot propagate into the section level. So it is not possible to update area in T2D2S.
