  3. Abstract:
  4. This paper describes the development of a numerical model with the ability to simulate and analyze the mechanical behavior of different 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 stiffness, 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, classification 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 briefly reviewed in this paper. Also, due to the multitude of influencing 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 Stiffness (Sini) of DBFEB connection have been conducted using regression analysis of FEM results. © 2017 Sharif University of Technology
