Extended exact least-weight truss layouts—Part II: Unsymmetric cantilevers

In Part I of this study, the optimal bar layout and adjoint displacement fields were derived for cantilever trusses that are symmetric about a horizontal axis. In this paper, the above results are generalized to unsymmetric trusses and a number of further extensions to other support and load conditions are outlined briefly. Most results are verified by comparisons with discretized optimal layouts of trusses and perforated plates.
