Abstract — The paper presents a proposal to create a new one-dimensional (1-D) finite element that can substitute for the three-dimensional (3-D) finite model of connection elements in static analysis. The study is conducted on a simple small frame. First, a 3-D model is constructed, followed by the construction of an equivalent two-dimensional (2-D) one. At the final stage, the results of the static analysis of many proposed 1-D element models are compared with the results of the 2-D model. With a special treatment of the connection elements, the results of the analysis of the new 1-D finite element models agree well with the results of the 2-D model.
Keywords: Structures, Finite element methods, Condensation, Timoshenko beam, Connection element, and Small frames.
