Special Issue Information

Dear Colleagues,

This Special Issue aims to promote a close examination and foster a debate on recent advances and future challenges for the seismic design, assessment, and retrofit of steel buildings. It is envisaged that international researchers will share novel materials, technologies, and methodologies for the design, assessment, and retrofitting of steel structures at local and global seismic level. Proposals for the implementation of the next generation of seismic codes and revision of the existing standards are also highly appreciated. The main topics covered within this Special Issue cover the following aspects:

  • New and existing buildings
  • Industrial buildings
  • Light-weight structures
  • Non-structural components
  • Codification for seismic design, assessment and retrofitting.
  • Seismic resistant steel joints
  • Cyclic behaviour of members, joints and components
  • Existing and novel approaches for seismic assessment of new and/or existing structures
  • Characterization of seismic input
  • Advanced modelling for seismic performance assessment
  • Performance criteria
  • Local and global response analysis
  • Seismic fragility curves
  • Seismic retrofitting methods
  • Loss assessment and risk analysis of existing structures
  • Experimental tests for response analysis
  • Shake table and pseudo-dynamic tests for steel components and systems
  • Hybrid testing and Hybrid simulations
  • Tall buildings

Please consider that the above topics may not be exhaustive, so feel free to submit your contributions on any additional topic that could be relevant to the field of steel structures in seismic areas.

Study on Seismic Isolation of Long Span Double Deck Steel Truss Continuous Girder Bridge
by Yongjian Chen, Honglie Sun and Zhenfa Feng

In order to improve the seismic performance of long-span double deck steel truss continuous girder bridge, taking Dao Qing Chau Bridge in Fuzhou as an engineering background, the isolation scheme of friction pendulum bearing (FPB) and friction pendulum bearing combined with viscous dampers is applied to study seismic performance. A three-dimensional dynamic model of the bridge is established using SAP2000. Taking three artificial seismic waves as seismic excitation, the seismic response of the seismic structure is calculated by nonlinear time history integration, and is then compared with the seismic response of the seismic reduction and isolation structure. The results show that the friction pendulum bearing (FPB) scheme and combined seismic dissipation and isolation (CSDI) scheme show a good seismic dissipation and isolation effect and ensure the safety of the bridge structure. However, for whole-bridge isolation, friction pendulum bearing (FPB) will produce certain residual deformations and additional stress of the bearing under the conditions of temperature and external load. For the purpose of protecting the bearing, it is recommended to use the combined seismic dissipation and isolation (CSDI) scheme. Full article

The design of steel chevron-braced frames as per Eurocode 8 is based on the idea that only the braces should buckle and yield during ground motions, while other members should remain elastic. The elastic design of the braced frames is also allowed. However, in both cases, the seismic performance of the frame may be compromised because of premature yielding/buckling of columns. This paper proposes an alternative design procedure that promotes yielding of beams in addition to yielding of braces. This mitigates the vertical unbalanced force transmitted by compressive and tensile braces to the beam and in turn reduces the internal forces of the columns. The result is the overall improvement of the seismic performance owing to the reduction of the number of cases in which failure of the columns occurs before full exploitation of the ductility capacity of the dissipative members. The proposed design procedure is validated by incremental dynamic analyses performed on a set of chevron-braced frames. In particular, the peak ground accelerations of the frames designed by the proposed procedure at the attainment of Significant Damage and Collapse Prevention limit states are determined and compared to those of frames designed according to Eurocode 8. Furthermore, frames designed according to the Eurocodes and to the proposed method are compared in terms of structural cost. Full article

The capacity of a structure can be assessed using inelastic analysis, requiring sophisticated numerical procedures such as pushover and incremental dynamic analyses. A simplified method for the evaluation of the seismic performance of steel moment resisting frames (MRFs) to be used in everyday practice has been recently proposed. This method evaluates the capacity of buildings employing an analytical trilinear model without resorting to any non−linear analysis. Despite the methodologies suggested by codes, the assessing procedure herein described is of easy application, also by hand calculation. Furthermore, it constitutes a suitable tool to check the capacity of the buildings designed with the new seismic code prescriptions. The proposed methodology has been set up through a large parametric analysis, carried out on 420frames designed according to three different approaches: the theory of plastic mechanism control (TPMC), ensuring the design of structures showing global collapse mechanism (GMRFs), the one based on the Eurocode 8 design requirements (SMRFs), and a simple design against horizontal loads (OMRFs) without specific seismic requirements. In this paper, some examples of the application of this simplified methodology are proposed with references to structures supposed to exhibit global, partial and soft storey mechanism. Full article
