“…In recent years there has been an increased interest in the use of FE models in studying the behaviour of beam-to-column semi-rigid joints in fire [28][29][30][31][32][33][34][35][36][37][38]. The main merit of using FE models over other numerical modelling techniques is that the behaviour of the joint can be inspected in which the failure mechanism of the joint as well as the deformation of different components can be observed.…”

“…Al-Jabri et al [4] reviewed the available FE models that have been developed by various authors to predict the response of different joints at elevated temperature taking into account geometrical and materials non-linearities. These authors observed that there were few FE codes that were developed to predict the elevated temperature behaviour of joints while ABAQUS and ANSYS are the most widely used general purpose FE programs which were used to model different types of bare-steel joint configurations at both ambient-and elevated-temperature [28][29][30][31][32][33][34][35][36][37][38]. Both programs have demonstrated ability to predict the behaviour of joints accurately.…”

“…Both programs have demonstrated ability to predict the behaviour of joints accurately. The author used the general purpose FE programs ABAQUS and ANSYS to model the behaviour of semi-rigid bare-steel flush end-plate joints in fire [30,35], respectively. The finite element models were used to establish the moment-rotation characteristics of the flush end plate bare-steel joints with a concentrated force and elevated temperatures as well as to study the failure modes of different components and compare them with experimental observations.…”

“…In detail, a Coulomb coe cient of friction equal to 0.3 is de ned for sliding resistance. In the earlier nite element studies of bolted connections, such as those by Abolmaali et al [17], Feng et al [18], and Al-Jabri et al [19], pretension e ects in the bolts caused by the tightening of each bolt were simulated through using the bolt pretension element, where it acted as a connecting element to connect the two imaginary parts of the bolt shank.…”

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.

SUMMARY Considering the deterioration of steel properties by temperature increase and the importance of the influence of connection behavior on the behavior of steel structures, we find that the exact understanding of the behavior of a specific steel connection in fire as well as the information about the effect of fire on the principal constitutive characteristics of the connection is necessary for safe design against fire. Thus, in this paper, the behavior of welded angle connections is studied at elevated temperatures using the abaqus finite element software. Steel members and connection components are considered to behave nonlinearly; the degradation of steel properties with increasing temperature is considered according to EC3, BS5950 recommendations. The results of finite element and experimental tests conducted on welded angle connections are compared, and the obtained failure modes and moment–rotation–temperature characteristics are in good agreement with those associated with the experimental tests. In the following, since the knowledge about moment–temperature–rotation behavior of a specific connection is needed for a fire‐resistant design, these properties are accurately determined, and finally, the effect of some parameters such as the moment applied on beam, change of column axial force and change of beam shear force on the stiffness of these connections at elevated temperatures is determined.
