A consistent UVLWT formulation for laminated plane frame analysis considering semi-rigid connections

From the analyzed examples, we can state that the UVLWT formulation and the developed connections presents the following capabilities:(i) geometric nonlinear modeling of laminated 2D frames assembled by slender or thick bars, without presenting problems of locking and system of equations bad conditioning; (ii) geometrically exact modeling of curved bars; (iii) consistent modeling of general flexible or rigid internal corner connections; (iv) consistent modeling of elastic external supports; (v) Zig-Zag effect consideration with accurate transverse stress distribution and (vi) straightforward extension for 3D applications as the finite rotation concept is not used.
