“…In surface coupling, there is no overlapping of different models and different models can be coupled using one of the following methods: (a) transition element method; and (b) multipoint constraint (MPC) method. Transition elements can be used for shell-solid transition [23], beam-solid transition [24,25], and beam-shell transition [26]. Unfortunately, the transition elements have not been widely adopted because of its limitations.…”

ABSTRACT:The interruption of electrical service due to failure of transmission tower structures can have devastating economic and social consequences. The current method for analyzing transmission tower structures is often to treat the angle members of the tower as either pin-ended truss elements or fix-ended beam elements. This approach ignores the effects of joint flexibility, local geometric and material nonlinearity, bolt slippage and deformation, making the structural analysis and design of the tower inadequate. In an effort to improve the structural analysis of transmission tower structures, this study aims at developing a multi-scale modeling method for transmission tower structures, in which critical joints of the tower are modeled using solid elements in a great detail while other members are modeled with common beam elements. The critical joint model includes gusset plates, angle members and bolts. The effects of local geometric and material nonlinearity and the contact problem between the bolts, plates and angles are all taken into consideration. New multi-point constraints for beam-to-solid connections at interface developed by the authors are used to couple the critical local joint model with the beam elements to form a multi-scale model of the tower. To verify the multi-scale modeling method, a physical model of a transmission tower structure was constructed and tested. The displacement and strain response of the tower model measured from the static tests are compared with the numerical results. The dynamic characteristics of the tower model identified from the dynamic tests are also compared with the numerical results. The comparative results show that the multi-scale modeling method is feasible and accurate for simultaneously predicting both global and local responses as well as estimating dynamic characteristics of the transmission tower structure.

“…In [29][30][31], constraint equations are used to couple models with different geometric dimensions and stress states. Alternatively, transition elements are used by a number of researchers to couple beam, plate and shell elements with solid elements [32][33][34][35].…”

“…Those transition elements show effective and reliable results in the analysis of the connections of coupled wall structures, and accuracy in modeling connecting beam. GARUSI and TRALLI [7] presented a new transition element for modeling solid-beam and plate-to-beam connections based on the hybrid stress method. The stress field solution of the de Saint Venant problem was assumed within the transition element.…”

An element coupling model (ECM) method was proposed to simulate the global behavior and local damage of a structure. In order to reflect the local damage and improve the computational efficiency, three-dimensional (3D) solid elements and one-dimensional (1D) beam element were coupled by the multi-point constraint equations. A reduced scale ‫8׃1‬ model test was simulated by the ECM and a full three dimensional model (3DM) contrastively. The results show that the global behavior and local damages of ECM agree well with the test and 3DM. It is indicated that the proposed method can be used in the structural nonlinear analysis accurately and efficiently.
