“…In the same spirit, finite elements for solid to beam transitions were introduced a few years later for small strain plane and three-dimensional (3D) problems. [4][5][6] Another linking strategy for continuum and structural numerical models that has been advocated in the past consists in using point-to-point and multipoint constraints (MPC). Examples of this approach can be found for beam-to-shell 7,8 and beam-to-solid connections.…”

Summary Two variational principles are proposed that describe equilibrium problems with connected nonlinear beams and solids. The principles extend the classical principle of minimum potential energy for beams and deformable bodies incorporating constraints that weakly enforce the beam kinematics at the common interface using either Lagrange multipliers or penalty terms. In contrast with existing alternatives, in the new approach, the surfaces of bodies connected to beams can deform in an energetically optimal way while globally behaving as beam cross sections. This allows, eg, warping and Poisson effects in beam/solid interfaces. Finite element implementations of the new principles are described in detail and application examples are provided that illustrate their use.

“…The finite element method has also been applied to analyse coupled shear walls by modelling the walls, coupling beams and beam-wall joints with plane stress elements, beam elements with no rigid arms, and transition zone elements, respectively [11]. These studies were generally based on assumed elasto-plastic or nonlinear load-deflection behaviour of the coupling beams and aimed at evaluating the possible effects of the nonlinear behaviour of the coupling beams on the overall structural performance of the coupled shear wall structure.…”

“…Then a combination of the 3D and 1D technique may be a good method to capture the global-local behavior. Some methods to couple different dimensional elements have been presented (McCune et al 2000;Shim et al 2002) and used upon RC structures (Kim and Hong 1995;Garusi and Tralli 2002;Yue et al 2011).…”

In order to study the mechanical behavior and the failure mode of existing RC frame structure, a real three-story RC frame structure including external masonry walls was tested by lateral loading. The global structure exhibited a column-sway collapse mechanism with shear-flexure hinges at the top ends of the columns at the first story. The external wall along the loading direction at the bottom story exceeded its ultimate capacity indicated by a large through-the-wall diagonal crack. A Local-Fine Model (LFM) is presented to capture the global-local nonlinear behavior of the test structure. Based on the damage law of the frame structure, the test structure is divided into linear regions with one-dimensional elements and nonlinear regions with three-dimensional elements in the LFM. All damages are assumed only occurred in the nonlinear regions. Different dimensional elements are coupled by the multi-point constraint equations. The calculated global failure progress, bearing capacity and the local concrete strain agrees closely with the test. The calculated local steel yield progress is in accordance with the test failure progress. Those results indicate the presented LFM can reflect the global behavior and local damages of the structure accurately.
