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.

Available in PDF, EPUB and Kindle. Book excerpt: Tests were performed on four steel portal frames, 8 feet high and 12 feet long, fabricated from 12WF27 rolled sections. The frames were constant in cross section and hinged at their bases. Maximum static and dynamic loads of 75,000 and 80,000 pounds, respectively, were applied over one column of each frame to simulate a horizontal, travelling, blast wave. The rise times of the dynamic loads were approximately 2 to 3 milliseconds. The loads then decayed exponentially to zero in about 1 second. An equivalent triangular load-time function was used for analysis. After several dynamic loads were placed on one column of one frame, the opposite column was loaded to determine the effect of repeated and reversed loading. The applied loads and the resulting deflections, strains, and accelerations were measured. The reduced data are presented in graphical and tabular forms. The multiplemode, the simplified, and the response-chart methods of dynamic analysis were performed, and the results were compared with the experimental values. The multiple-mode analysis proved to be the only method that can be used to predetermine the locations of plastic hinges, however, the single-degree of-freedom system adequately described the maximum displacement of the frame in both the elastic and inelastic ranges. Good correlation was obtained between theoretical and experimental values for both the static and dynamic tests. The dynamic response factor and the dynamic shear factors were 1.9 and 1.4 respectively. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: This book is intended for classroom teaching in architectural and civil engineering at the graduate and undergraduate levels. Although it has been developed from lecture notes given in structural steel design, it can be useful to practicing engineers. Many of the examples presented in this book are drawn from the field of design of structures. Design of Steel Structures can be used for one or two semesters of three hours each on the undergraduate level. For a two-semester curriculum, Chapters 1 through 8 can be used during the first semester. Heavy emphasis should be placed on Chapters 1 through 5, giving the student a brief exposure to the consideration of wind and earthquakes in the design of buildings. With the new federal requirements vis a vis wind and earthquake hazards, it is beneficial to the student to have some under standing of the underlying concepts in this field. In addition to the class lectures, the instructor should require the student to submit a term project that includes the complete structural design of a multi-story building using standard design procedures as specified by AISC Specifications. Thus, the use of the AISC Steel Construction Manual is a must in teaching this course. In the second semester, Chapters 9 through 13 should be covered. At the undergraduate level, Chapters 11 through 13 should be used on a limited basis, leaving the student more time to concentrate on composite construction and built-up girders.

Download or read book Steel Designers Manual written by SCI (Steel Construction Institute) and published by John Wiley & Sons. This book was released on 2016-06-27 with total page 1410 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2010 the then current European national standards for building and construction were replaced by the EN Eurocodes, a set of pan-European model building codes developed by the European Committee for Standardization. The Eurocodes are a series of 10 European Standards (EN 1990 – EN 1999) that provide a common approach for the design of buildings, other civil engineering works and construction products. The design standards embodied in these Eurocodes will be used for all European public works and are set to become the de-facto standard for the private sector in Europe, with probable adoption in many other countries. This classic manual on structural steelwork design was first published in 1955, since when it has sold many tens of thousands of copies worldwide. For the seventh edition of the Steel Designers' Manual all chapters have been comprehensively reviewed, revised to ensure they reflect current approaches and best practice, and brought in to compliance with EN 1993: Design of Steel Structures (the so-called Eurocode 3).

This book was released on 2017-06-19 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book details the basic concepts and the design rules included in Eurocode 3 "Design of steel structures" Part 1-8 "Design of joints". Joints in composite construction are also addressed through references to Eurocode 4 "Design of composite steel and concrete structures" Part 1-1 "General rules and rules for buildings". Moreover, the relevant UK National Annexes are also taken into account. Attention has to be duly paid to the joints when designing a steel or composite structure, in terms of the global safety of the construction, and also in terms of the overall cost, including fabrication, transportation and erection. Therefore, in this book, the design of the joints themselves is widely detailed, and aspects of selection of joint configuration and integration of the joints into the analysis and the design process of the whole construction are also fully covered. Connections using mechanical fasteners, welded connections, simple joints, moment-resisting joints and lattice girder joints are considered. Various joint configurations are treated, including beam-to-column, beam-to-beam, column bases, and beam and column splice configurations, under different loading situations (axial forces, shear forces, bending moments and their combinations). The book also briefly summarises the available knowledge relating to the application of the Eurocode rules to joints under fire, fatigue, earthquake, etc., and also to joints in a structure subjected to exceptional loadings, where the risk of progressive collapse has to be mitigated. Finally, there are some worked examples, plus references to already published examples and to design tools, which will provide practical help to practitioners.
