Optimal archgrids: Allowance for selfweight
TLDR
In this paper, the optimal design of archgrids for a combination of given external loads and self-weight is discussed, and three different methods are described and illustrated with examples of one-and two-way arch systems.About:

Note on topology optimization of continuum structures including self-weight
Michaël Bruyneel,Pierre Duysinx +1 more
TL;DR: In this article, the authors proposed to investigate topology optimization with density-dependent body forces and especially self-weight loading and showed that important improvements are achieved when the solution is carried out using the gradient-based method of moving asymptotes (GBMMA) approximations.

On plane Prager-structures—I☆
TL;DR: In this paper, a systematic method for constructing plane Prager-structures for any system of vertical loads is outlined and illustrated with examples, where the sign of all member forces must be the same and the vertical location of all external loads is to be optimized.

Optimal Plastic Design: Allowance for Self-Weight
TL;DR: In this article, a modification of the Prager-Shield condition is introduced, which requires the strain rates to be everywhere equal to the gradient of the specific cost function, with a view to optimizing structures for a combination of applied loads and self-weight (bodyforces).
