“…Kaliakin and Li (1995) introduced macro-element composed of two adjoined rectangular fournodded element for interaction analysis of soil and strip footing compatible to two DOF per node. Coutinho et al (2003) developed an interface link with four corner nodes, two DOF per each. This element was then used for interaction analysis of soil and strip footing.…”

Interfacial behavior between soil and shallow foundation has been found so influential to combined soil-footing performance and redistribution of forces in the superstructure. This study introduces a new thin-layer interface element formulated within the context of finite element method to idealize interfacial behavior of soil-framed structure interaction with new combination of degrees of freedom at top and bottom sides of the interface element, compatible with both isoparametric beam and quadrilateral element. This research also tends to conduct a parametric study on respective parameters of the new joint element. Presence of interface element showed considerable changes in the performance of the framed structure under quasi-static loading.

“…(20) is established according to the discrete-interface approach [27]. Therefore, in order to avoid spurious oscillations found with Gaussian rules, a Newton-Cotes/ Lobatto scheme is adopted [36][37][38][39]. As a consequence, the integration points become coincident with the nodes added along the discontinuity capturing the jump.…”

a b s t r a c tIn this paper, strong discontinuities are embedded in finite elements to describe fracture in quasi-brittle materials. A new formulation is presented in which global nodes are introduced along the crack path. The displacement jumps are transferred to the element nodes as a rigid body motion. This approach is compared to the discrete approach, in which interface elements are inserted to model discontinuities. The adopted embedded discontinuities and the interface elements share similar kinematics as well as the same numerical integration schemes. Thus, the present formulation is obtained within the framework of a discrete approach and this is why it is called the discrete strong discontinuity approach (DSDA). Numerical tests are considered, namely a shear band, a mode-I and a mixed-mode fracture examples and a failure test of a RC beam externally reinforced with a steel sheet. Results are compared with those obtained from analyses using interface elements and with experimental results. Finally, conclusions are drawn with respect to mesh independence and robustness of the method.
