Non-linear analysis of steel–concrete composite frames with full and partial shear connection subjected to seismic loads

Composite structural elements of steel-concrete began to be used only in 1960 after the development of methods and constructive dispositions that ensured the functionality of these two materials together. In order to verify the importance of the participation of the axial mode in the frequency spectrum of the free vibration problem in composite beams with deformable shear connection, several analyses for 4 different boundary conditions and stiffness connection variation were performed. The analysis of the problem was carried out by development and computational implementation of a finite element for composite beams with partial interaction in the longitudinal direction applied to the problem of free vibrations. The solutions to this problem in the literature are scarce, and project recommendations are simplified. The results show that the finite element exhibits an excellent performance compared with the analytical results and as the axial mode has a high modal contribution, despite the boundary condition and stiffness connection.

“…In the ASCE 7-05 [19], the elastic design spectrum is modified by the response modification factor R, which is set to 6.0 for C-PRMF and to 8.0 for steel frames. Numerical studies by Ciutina et al [12] and Bursi et al [3] confirm a good performance of multi-storey PS frames; hence, a design value q = 6.0 was adopted. The particular structure, herein studied, and the differences between examined codes about height limitations and behaviour factor imply that an experimental assessment of seismic performance of the composite PR-PS MRF should be carried out to investigate the actual behaviour factor and other structural properties.…”

“…Global beam hinging mechanisms for earthquake resistance can be achieved at a reduced cost as the force demand on joints and columns is governed by the expected capacity of the ductile connection components rather than by the beam flexural capacity. The behaviour of such a framing system heavily depends on the joint response and a significant part of past research on steel-concrete composite PS frames was devoted to the development of connection details able to behave in a ductile manner under cyclic inelastic loading [3][4][5][6][7][8][9][10]. Numerical studies were also performed to verify the global seismic performance of partially restrained (PR) composite frame structures [11][12][13].…”

SUMMARYA multi-level pseudo-dynamic (PSD) seismic test programme was performed on a full-scale three-bay twostorey steel-concrete composite moment-resisting frame built with partially encased composite columns and partial-strength connections. The system was designed to provide strength and ductility for earthquake resistance with energy dissipation located in ductile components of beam-to-column joints including flexural yielding of beam end-plates and shear yielding of the column web panel zone. In addition, the response of the frame depending on the column base yielding was analysed. Firstly, the design of the test structure is presented in the paper, with particular emphasis on the ductile detailing of beam-to-column joints. Details of the construction of the test structure and the test set-up are also given. The paper then provides a description of the non-linear static and dynamic analytical studies that were carried out to preliminary assess the seismic performance of the test structure and establish a comprehensive multi-level PSD seismic test programme. The resulting test protocol included the application of a spectrum-compatible earthquake ground motion scaled to four different peak ground acceleration levels to reproduce an elastic response as well as serviceability, ultimate, and collapse limit state conditions, respectively. Severe damage to the building was finally induced by a cyclic test with stepwise increasing displacement amplitudes.
