Available in PDF, EPUB and Kindle. Book excerpt: The widespread and unexpected damage to welded connections during recent earthquakes led to the investigation of alternatives for the construction of steel frames in seismic areas. Bolted semi-rigid connections have been recognized as an attractive alternative to welded connections. However, existing knowledge on the behavior of the connection is either from testing of beam-to-column subassemblies under idealized load and boundary conditions, or from analytical studies. In addition, the system-level experimental behavior of semi-rigidly connected frames using real earthquake motions to conclusively verify the full potential of semi-rigidity (implying also partial-strength) in earthquake resistance application is lacking. To this end, an advanced hybrid simulation approach for the seismic assessment of steel frames with semi-rigid connections was proposed and successfully completed. Furthermore, nonlinear dynamic response-history analyses of semi-rigid frames with varying design parameters were conducted to evaluate the system performance under seismic events. The results of the hybrid simulation and the parametric studies are used to quantify various fundamental code parameters needed for the seismic design of structures. The hybrid simulation included the most reliable, realistic, and computationally efficient experimental and analytical modules, which were developed and successfully integrated in a closed-loop system-level simulation. Three hybrid simulations were conducted on three different partial-strength semi-rigid frames with connection capacities that are a percentage of the plastic moment capacity of the beam (70% Mpbeam, 50% Mpbeam, and 30% Mpbeam). The simulations utilized the large-scale Multi-Axial Full-Scale Sub-Structured Testing and Simulation (MUST-SIM) facility at the University of Illinois and included a full-scale physical specimen for the experimental module and a 2D finite element model for the analytical module. The experimental component consisted of a beam-column subassembly with top-and seat-angle with double web-angle connecting the beam to the column. The analytical component is an inelastic finite element model with the connections modeled using a refined 2D continuum elements that is capable of capturing all relevant deformation and inelastic features of the connection. In addition to the hybrid simulation, nonlinear dynamic response-history analyses were conducted, on frames with three different connection capacities (70% Mpbeam, 50% Mpbeam, and 30% Mpbeam), using a collection of ground motion records scaled to the maximum considered earthquake (MCE). The analyses were aimed at investigating the effect of varying different design parameters on the seismic response and period elongation of the frames. The design parameters, in addition to connection strength, included yield strength of the angle material, coefficient of friction between faying surfaces, and the amount of slip allowed in the connection. The results of the hybrid simulation along with the analytical studies were used to evaluate more realistic fundamental code parameters needed for the seismic design of frames. The parameters included the equivalent damping ratio, 1̐ðeq, the inelastic period of the structure, Tinealstic, and a demand-based force reduction factor, Rdemand. The evaluated parameters can be used to better estimate the design base shear using a simplified design spectrum, allowing for safer and economical design of semi-rigid frames under seismic events.

Available in PDF, EPUB and Kindle. Book excerpt: Stability Design of Steel Frames provides a summary of the behavior, analysis and design of structural steel members and frames with flexibly-jointed connections. The book presents the theory and design of structural stability and includes extensions of computer-based analyses for individual members in space with imperfections. It also shows how connection flexibility influences the behavior and design of steel frames and how designers must consider this in a limit-state analysis and design procedure. The clearly written text and extensive bibliography make this a practical book for advanced students, researchers and professionals in civil and structural engineering, as well as a useful supplement to traditional books on the theory and design of structural stability.

Available in PDF, EPUB and Kindle. Book excerpt: At the design stage, column-beam connections of steel structures are assumed as fully rigid or as hinges, and the design is completed with these assumptions. On the other hand, in practice, steel column-beam connections show neither fully rigid nor fully hinge behaviour, and the characteristic behaviour of the connections lies between these two special cases. Performing realistic calculation of these forces and knowing the behaviour of structures close to reality will decrease life and goods losses to the minimum level in a probable of earthquake to be encountered in the future. In this study, seismic performance of 2-D steel frames were evaluated by Capacity Spectrum Method proposed in the ATC 40 document published in 1996. A new computer program was developed in order to define all geometric and loading data and to perform nonlinear analysis of rigid and semi rigid steel frames for which the performances will be evaluated. In case studies, 3-Floor Steel Frames that have different bay numbers were investigated in various forms according to the rigid and different semi rigid connection types. In addition, the performances these frames for various seismic regions and soil conditions were compared. According to the results, it was observed that semi rigidly connected frames are under the effect of smaller ground acceleration have greater displacement values. As a consequence of this ductile and energy dissipative response, it was seen that the stresses in the members of frame become considerably small, relative to the stresses in the rigid frames’. Furthermore, the performances of semi-rigid frames can be affected negatively beyond such a low rigidity. Consequently, the most convenient design should be made according to the seismic and soil region where the structure to be constructed by performing the necessary studies on the connection details in order to achieve desired performance, serviceability and optimum member criteria.

This book was released on 2000-04-27 with total page 686 pages. Available in PDF, EPUB and Kindle. Book excerpt: An unexpected brittle failure of connections and of members occurred during the last earthquakes of Northridge and Kobe. For this reason a heightened awareness developed in the international scientific community, particularly in the earthquake prone countries of the Mediterranean and Eastern Europe, of the urgent need to investigate this topic. The contents of this volume result from a European project dealing with the 'Reliability of moment resistant connections of steel frames in seismic areas' (RECOS), developed between 1997 and 1999 within the INCO-Copernicus joint research projects of the 4th Framework Program. The 30 month project focused on five key areas: *Analysis and syntheses of research results, including code provisos, in relation with the evidence of the Northridge and Kobe earthquakes; *Identification and evaluation through experimental means of the structural performance of beam-to-column connections under cyclic loading; *Setting up of sophisticated models for interpreting the connection response; *Numerical study on the connection influence on the seismic response of steel buildings; *Assessment of new criteria for selecting the behaviour factor for different structural schemes and definition of the corresponding range of validity in relation of the connection typologies.
