Available in PDF, EPUB and Kindle. Book excerpt: This investigation was into the computized design and analysis of portal frame type structures, which may include members of varying section, by both elastic and plastic methods of analysis. The objectives were to produce suitable design guide lines for the sizing of the frame members, to produce an interactive plastic analysis program for use on micro computers and to expand the capability of the existing elasto-plastic analysis program at the University of Bradford, to cope with haunched members and to incorporate any applicable time and space saving devices. The design guide lines were to be an extension of D I Blockley's paper "The Design of Single Storey Pitched Roof Portal Frames", published in 1970. Repeated analysis and geometrically similar frames with varying sections were performed and the results combined with the recommendations from Blockley's paper, to produce design guides for the sizing and position of the individual members of the frame. To produce a suitable plastic analysis program for use on a micro computer, computer, the Reactant Bending Moment or Graphical method analysis was chosen. The advantages of this method are, that it is commonly used in the design office, it allows checking at intermediate stages in the analysis, and the free bending moment distribution aids the selection of appropriate hinge positions. The existing program at the University of Bradford was to be extended by introduction of routines which would allow haunched members and multiply loading to any member, this would reduce computer storage and solution time, but a special solution routine was required to determine the formation position of a hinge along a member. The three objectives were completed and where possible compared with other proven methods of analysis.

Available in PDF, EPUB and Kindle. Book excerpt: Plastic Design of Steel Frames assesses the current status and future direction of computer-based analyses of inelastic strength and stability for direct frame design. It shows how design rules are used in practical frame design and provides an introduction to the second-order theory of inelastic frame design. The book includes two computer programs on a diskette: one for the first-order analyses and the other for the second-order plastic hinge analysis of planar frame design. The second-order program can be used to predict realistic strengths and stabilities of planar frames, thereby eliminating the tedious task of estimating factors for individual member capacity checks. Both programs include clear input instructions. The diskette also contains the Fortran source-code listing for the second-order plastic-hinge analysis, enabling the user to customize the program. The programs will run on an IBM PC-AT or equivalent machine with 640 kB of memory and 30 MB hard drive.

Download or read book Plastic Design of Frames 1 Fundamentals written by J. Baker and published by Cambridge University Press. This book was released on 1969-06-02 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: When this volume was first published, plastic theory was the most modern method of structural analysis, and it made possible the direct design of steel frames in a way not available with only elastic methods. It is now recognized that this theory is also fundamental to structural design in materials such as reinforced concrete and aluminium. This is the first volume of a two-volume work by Professors Baker and Heyman that expounds and illustrates the methods of plastic design. Volume 1 gives the elements of the theory and covers the needs of most undergraduates and designers. A special feature of this work is the large number of exercises (140 in all) with answers. Volume 2 deals with advanced topics of theoretical analysis and practical design. The examples and the methods presented herein are extremely valuable to the engineer. The quality of the writing makes Professors Baker and Heyman's book a pleasure to read. Lord Baker (Sir John Fleetwood Baker, 1901-1985) was Professor of Mechanical Sciences and Head of the Department of Engineering at the University of Cambridge from 1943 to 1968. He was a Fellow of the Royal Society. Baker's pioneering research led to the development of the plastic theory of design, originally used for steel frames but now recognized as being valid for many structural materials, such as aluminium and reinforced concrete. Additionally, Baker was responsible for many curriculum innovations at the university and was the author of The Steel Skeleton, a two-volume work. Jacques Heyman is the former Head of the Department of Engineering at the University of Cambridge and the author of ten books, including The Stone Skeleton, Elements of the Theory of Structures, Structural Analysis: A Historical Approach, Elements of Stress Analysis, and the two-volume set Plastic Design of Frames: Volume 1. Fundamentals with Lord Baker and Volume 2. Applications. He is a Fellow of the Society of Antiquaries, the Institution of Civil Engineers, and the Royal Academy of Engineering. He acted as a consulting engineer for a number of English cathedrals and as a member of the Architectural Advisory Panel for Westminster Abbey and of the Cathedrals Fabric Commission for England, and he has served on many British standards committees. The Stone Skeleton won the Choice Outstanding Academic Books Award in 1996.

Available in PDF, EPUB and Kindle. Book excerpt: Practicing engineers can confidently design hot-rolled steel portal frame structure if it is kept at ambient temperature. However, as they are not aware of the potential collapse behaviour of such frames in fire, they tend to use heavy foundations with expensive fire protection materials applied to all the columns, rafters and column bases to ensure the structural integrity, and prevent premature collapse. The research presented in this thesis aims to provide computational techniques and solutions for studying the possible behaviour of different hot-rolled steel portal frames in fire considering the partial strength of column bases with partial insulations applied to the columns. Before tackling the effect of partial strength of column bases, a comparative study between two different dynamic methods for solving such problems, the implicit dynamic method and the explicit dynamic method, has been undertaken considering fire, large deformations, complex geometry, boundary conditions and degradation of material stiffness. For such analyses, the cost of computation is important as well as the accuracy, robustness and stability of the analysis. It is found that obtaining similar results are possible by using both of the dynamic methods, however, the analyses time differ significantly. It has been established that if the applied artificial inertia forces in terms of residual forces can be magnified and if the automatic time incrementation scheme is activated in the implicit dynamic method then this method shows significant superiority over the explicit dynamic method both in terms of cost of computation and accuracy of results for analysing such structure. Once the proper dynamic method has been selected, all of the analyses of portal frame structure in fire have been conducted by using this particular dynamic method. The developed model using the implicit dynamic method has been used for studying the effect of partial strength of column bases. A non-linear elasto-plastic implicit dynamic finite element model of a single-span pitched roof steel portal frame building in fire is set-up and used to assess the adequacy of the design method provided by the Steel Construction Institute (the SCI design method). Both 2-D and 3-D models are used to analyze a building similar to the Exemplar frame described in the SCI design guide. Using the 2-D model, a series of parametric study on different frames is conducted. It is shown that the value of the overturning moment,MOTM, calculated in accordance with the SCI design method, is not sufficient to prevent collapse of the frame before 890°C. It is established that if MOTM is increased the eaves rotations are reduced significantly and reach close to 1° of the original shape, the limit specified by the SCI design method. The developed model has been extended for analyzing three other portalised frames, such as, multi-span portal frames, portalised truss frames and asymmetric portal frames. It is found that, apart from the multi-span frame, the model can be readily applied to the portalised truss frames and asymmetric portal frames without any computational overhead and loss of accuracy. However, for the multispan frame, the cost of computation is increased significantly. The computational cost is reduced by relaxing some tight tolerance parameters without losing any accuracy. For all of the frames, it has been observed that all the frames collapses when the column bases are perfectly pinned. However, when a partial strength is introduced at the column bases, the behaviour of the frames changed considerably. It is found that though the snap-through-buckling temperatures remain almost same, the collapse temperatures vary and the eaves rotations differ significantly. Similar to the single-span pitched roof portal frame it has been found that when MOTM is increased the eaves rotations are reduced significantly and reached close to 1° of the original shape. Based on the studies on different frames it is suggested that the MOTM given by the SCI method should be increased and considered within the region of 1.5MSCI to 2.0MSCI. Key words: steel portal frames, stability, snap-through-buckling, quasi-static and dynamic analysis, partial strength, semi-rigidity.
