Abstract. The seismic design strategy implemented in current codes

Simulation of fire exposure behavior to building structural elements using LISA FEA V.8.

“…This approach utilizes a continuum component to decide an answer that is nearer to reality. (Albahkali et al, 2021;Chen et al, 2021;D'Aniello, 2017;A. W. Efendi, 2022cA.…”

Removable friction dampers for low-damage steel beam-to-column joints

“…Therefore, the idea of low or free from damage structures has become very appealing in the last decades [2][3][4]. The use of friction connections is a viable and promising strategy to achieve this objective for steel structures [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. In the framework of Eurocodes, this type of connections can be classified as partial strength according to EN1993:1-8 [25] because their design resistance should be lower than the strength of the connected members to prevent any damage into the primary structural members.…”

“…However, the bolts that clamp the friction pad of AFCs can experience yielding due to large bending moment, shear and axial force interaction, which can induce clamping loss of the bolts and consequently pinching and loss of strength of the connections. On the contrary, these phenomena can be mitigated with the use of a symmetric friction connection (SFC) [16][17][18][19][20][21][22]. Latour et al [23] recently carried out an experimental study on SFCs with the friction damper applied by means of an additional haunch welded to the lower flange of the beam.…”
