Abstract. This paper describes the development of a numerical model with the ability to simulate and analyze the mechanical behavior of di erent types of Double Bolted Flush End-plate Beam (DBFEB) splice connections, which thus far has not been reported. Moreover, Bolted Flush End-plate Beam (BFEB) splice connections have been investigated for calibration of the results using Finite Element Modeling (FEM). The initial sti ness, rotation capacity, strength ratio, ductility, failure mode, and the performance of these two types of connections have been investigated and compared with each other with respect to FEMA 356. Also, classi cation of these two types of connections is performed by Eurocode 3 recommendation. The analyses have been calibrated and converted to experimental and analytical results, which are also brie y reviewed in this paper. Also, due to the multitude of in uencing parameters, an analytical description of the behavior of DBFEB connections has been delivered based on component method. Moreover, several parametric analyses on the Initial Rotational Sti ness (S ini ) of DBFEB connection have been conducted using regression analysis of FEM results.

Abstract. This research work describes the analysis of steel semi rigid joints that are subjected to bending and tension or compression. The main attention is focussed on the beam-to-beam and plate bolted joints. Usually influence of axial force is neglected. In fact, the level of tension or compression of axial force can be significant and has some impact on joint behaviour and on its stiffness and strength characteristics. Nowadays the most powerful method for the estimation of joints characteristics is the component method. The adaptation of the component method for the determination of joints characteristics under bending ant axial forces is shown in the paper. Some numerical results of calculations of steel frameworks are presented in this paper as well (Daniūnas and Urbonas 2008).

03.22: Calculation model for moment ‐rotation relationship of bottom‐through‐diaphragm top‐ring connection between SST columns and HSS beams

et al. 2017

Square steel tubular(SST) column and H-shaped steel(HSS) beam systems have been widely used in engineering applications. The structural performance of this system largely depends on the behavior of the connections. This paper presents a new type of connections with bottom-through-diaphragm and top-ring. Five specimens were tested under cyclic loadings to evaluate the seismic behavior and the moment-rotation relationships. Finite element models were developed and compared with experimental testing to verify the accuracy of the model. The calculation equation of momentrotation curves were proposed according to the analytical data of finite element model. Furthermore, the moment-rotation calculation model characterizing the general behavior of this new type connection were developed based on these parameters. The accuracy of the calculation model was examined by comparing with the results of finite element model. Finally, a reasonable momentrotation relationship was obtained using the parameters within this model.
