Objects can be linked to:
the element/member length proportion is “H” (half of the member length), “Q” (quarter of the member length), and “3Q” (3 x quarter of the member length)
Use cases:
- P2(H) – section property P2 is linked to half of the member length position;
- E1(Q) – Elastic foundation property E1 is linked to the quarter of the member length position;
Support O1 is placed on the distance of the three quarters of the length of the member S11:
Load LD11 is linked to half of the member length of the member S11:
the intersection of the elements/members (“member_label#:member_label#”)
Use cases:
- P1(S2:S6) – section property P1 is linked to the intersection of the members S2 and S6;
The support with the property of O5 is placed on the member S3 and linked to intersection of the member S3 and S5:
The release with the property of A1 is placed on the member S2 and intersection of the members S2 and S7. The release is located on the intersection S2:S7 in the direction of the end of member S2;
The other release with the property of A1 is placed on the member S7 and intersection of the members S2 and S7. The release is located on the intersection S2:S7 in the direction of the beginning of member S7:
Notes:
- the notation [-] and [+] is valid only for the definition of the releases;
- different placement of the releases on the rigid connectivity joint can cause a different redistribution of forces, like:
* grey color describes rigid part
- the notation by mentioning intersected members #:# (like S3:S17) solves the problem of the inaccuracy of input that can appear by entering the value of the coordinate (like 3.227).
the other object is “object_label#”
Use cases:
Section property P1 is applied on the member S1 from the member beginning till the support O1. Section property P2 is applied on the member S1 from the support O1 till the support O2. Finally, section property P1 is continued from the support O2 till the end of the member:
Load LD1 is applied on the member S1 on the beginning distance linked to the support O1 and the end distance linked to the support O2. Load LD2 is applied on the member S1 and linked to the support O2 coordinate decreased by 2.0 meters:
