This book was released on 2002 with total page 1572 pages. Available in PDF, EPUB and Kindle. Book excerpt: The scope of this study included full-scale experimentation, the development of a design procedure, and analytical studies of frames with PT connections. Full-scale interior PT connection subassembly specimens were subjected to severe inelastic cyclic loading. Design criteria and a design procedure for steel frames using PT connections were developed based on a performance-based design approach. Using nonlinear dynamic time history analyses, the seismic behavior of several 6-story, 4-bay PT MRFs with different design parameters was examined to evaluate the effects of these design parameters on the seismic response. The performance of the PT MRFs was compared to the performance of a MRF with welded connections.

Download or read book Theoretical and Experimental Analysis of Dissipative Beam-to-Column Joints in Moment Resisting Steel Frames written by Massimo Latour and published by Universal-Publishers. This book was released on 2011-07-11 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: Before the seismic events of Northridge (Los Angeles, 17 January 1994) and Hyogoken-Nanbu (Kobe, 17 January 1995), MRFs were supposed to be the most reliable seismic resistant systems due to the high number of dissipative zones that are able to develop. Before these earthquakes, especially in the United States, MRFs were realized, generally, by adopting fully welded connections, which, at the time, were retained to perform better compared to other joint typologies. In addition, the economic advantages deriving from the adoption of field fully welded connections strongly influenced choices of building owners and, as a result, led to the adoption of this joint typology in almost all pre-Northridge steel MRFs. After the Northridge earthquake, even though the loss of life was limited, the unexpected amount of damages occurred in structures adopting as seismic resistant system welded Moment Resisting Frames put into question the role played by welded connections on the whole of structural behavior. Therefore, after the seismic events, two strategies were identified to improve the behavior of fully welded connections. The first one is related to the improvement of the welding technique, usually strengthening the critical area subjected to fracture. The second one is based on the possibility of concentrating the energy dissipation in the beam, reducing the bending resistant area of beams by properly cutting the flanges in a zone close to beam-to-column connection. This weakening approach is commonly called RBS. A new design approach, which has been the subject of many studies in the last few decades, has gained growing interest in recent years. In fact, Eurocode 8 has opened the door to the idea of dissipating the seismic input energy in the connecting elements of beam-to-column joints. In this work, attention is focused on this last approach. The first part of the work is descriptive and deals with the historical development and, in general, with the seismic behavior of Moment Resisting Frames. In the same chapter, general concepts concerning the component method, as introduced by last version of Eurocode 3, are given. Finally, the influence of the joint behaviour on main characteristics of partial strength and/or semi-rigid MRFs is evaluated by properly accounting for existing literature. The third chapter deals with an experimental analysis on the cyclic behaviour of classical partial strength beam-to-column joints. The main scope of the experimental campaign is to show how to control the dissipative behaviour of joints by properly designing the weakest joint component and by over-strengthening the other connecting elements. A design procedure is pointed out and the comparison among the results obtained by cyclic tests is presented in terms of energy dissipation capacity. In addition, by monitoring during the experimental tests both the whole joint and the single joint components it is shown that the energy dissipated by the joint is equal to the sum of the energy dissipated by the joint components. This result assures that the first phase of the component approach, i.e. the component identification, is properly carried out and that interaction between components under cyclic loads is negligible. Chapter 4 represents the extension of the work carried out in the previous chapter. In fact, on the base of the obtained results, the goal is to provide a mechanical cyclic model for the prediction of the overall joint behaviour, starting from existing literature models. Hence, a state-of-the-art review is first presented and then, a model employed to set up a computer program devoted to the prediction of the cyclic behaviour of steel beam-to-column joints is defined. In particular, the proposed cyclic model adopts Kim & Engelhardt's approach to model the shear panel behavior, Cofie & Krawinkler's model to predict Panels in Tension and Compression cyclic behavior, and Piluso et al.'s model for the prediction of the T-stub modelling

Book Synopsis Experimental and Analytical Investigation of Panel Zone Behavior in Steel Moment Frames by : Sungyeob Shin
Download or read book Experimental and Analytical Investigation of Panel Zone Behavior in Steel Moment Frames written by Sungyeob Shin and published by . This book was released on 2017 with total page 844 pages. Available in PDF, EPUB and Kindle. Book excerpt: Steel moment resisting frames (MRFs) are one of the most commonly used lateral force resisting system for steel building construction located in regions of high seismic risk. Although steel moment frames were studied extensively following the 1994 Northridge Earthquake, one critical design issue is not yet completely understood: the role of the panel zone. Recent U.S. building codes have significantly increased the required shear strength of the panel zone for seismic applications. This leads to increased column sizes or the need for costly doubler plates. A number of past research studies showed that shear yielding of panel zones results in highly ductile behavior and provides a major contribution to frame deformation as an excellent source of energy dissipation. However, these same studies suggested that large panel zone shear deformation can cause high strain concentrations near the beam flange groove welds and can cause premature fracture at the joint. The overall goal of this research is to provide additional data to help answer the question: how much panel zone participation should be permitted in the inelastic seismic response of a steel moment frame? Despite a number of past studies on this issue, there are sharply conflicting views of how panel zones should be treated in design, both within the research community as well as within the building regulatory community. At the crux of the disagreements are concerns regarding fracture induced by panel zone yielding. There appears to be broad agreement that panel zone yielding is a highly ductile process. However, there is broad disagreement on the role that panel zone yielding plays in joint fracture. While there have been a number of past experimental studies on moment frame subassemblies with weak panel zones, the availability of data on large-scale specimens constructed using current US connection detailing and welding practices is very scarce. Further, the experimental database lacks critical data on panel zone behavior in deep columns and for columns subjected to significant axial forces. The primary focus of this dissertation is to provide much needed large-scale experimental data on the cyclic loading performance of steel moment frame joints with weak panel zones. The experimental study was supplemented by finite element analysis of the test specimens, intended to provide additional insights into the response of the test specimens. Cyclic loading tests were conducted on ten large-scale interior steel moment connections to study the seismic performance of the connections. The key variables for the tests were: panel zone strength; beam and column size; beam-to-column connection detail; and column axial stress. Nine of the ten test specimens performed well and met the acceptance criteria of 0.04 radian story drift angle for special moment frames in the current AISC Seismic Provisions. One specimen failed by fracture of the column flange just prior to achieving 0.04 radian story drift angle. In the experimental program, the weak panel zone specimens showed excellent performance, developing drift capacities as large as or larger than the strong panel zone specimens. The weak panel zone specimens exhibited less beam buckling and therefore less strength degradation than the strong panel zone specimens. Shear yielding of the panel zones in these specimens showed highly ductile behavior with stable hysteretic loops. The panel zone was an excellent energy dissipater. The results of this test program showed that acceptable performance of moment frame joints can be achieved over a range of panel zone strengths, varying from very weak to very strong. The experimental results also show that joints with weak panel zones can achieve very large inter-story drift angles prior to fracture. These experimental results suggest that current U.S. code requirements for panel zone strength merit reevaluation. Finite element models were developed of the test specimens, including a global model using shell elements and a local joint model using solid elements. The overall load deflection response of the test specimens predicted by the global models showed good agreement with the experimental results. Local joint models were developed to examine the potential for ductile fracture initiation using the Rupture Index. These studies suggested that the weak panel zone specimens should be far more prone to fracture than the strong panel zone specimens. This prediction, however, was inconsistent with the experimental observations. This suggest that using the Rupture Index as an indicator of the potential for ductile fracture initiation when comparing differing moment frame joint design options, as has been done by previous researchers, should be approached with caution.
