Book Synopsis A Computational Study of the Behaviour of Hot-rolled Portal Frames in Fire by : Mahbubur Rahman

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.
Book Synopsis Materials and Joints in Timber Structures by : Simon Aicher
Download or read book Materials and Joints in Timber Structures written by Simon Aicher and published by Springer Science & Business Media. This book was released on 2013-09-25 with total page 815 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the contributions from the RILEM International Symposium on Materials and Joints in Timber Structures that was held in Stuttgart, Germany from October 8 to 10, 2013. It covers recent developments in the materials and the joints used in modern timber structures. Regarding basic wooden materials, the contributions highlight the widened spectrum of products comprising cross-laminated timber, glulam and LVL from hardwoods and block glued elements. Timber concrete compounds, cement bonded wood composites and innovative light-weight constructions represent increasingly employed alternatives for floors, bridges and facades. With regard to jointing technologies, considerable advances in both mechanical connections and glued joints are presented. Self-tapping screws have created unprecedented options for reliable, strong as well as ductile joints and reinforcement technologies. Regarding adhesives, which constitute the basis of the jointing/laminating technology of modern timber products, extended options for tailor-made bonding solutions have to be stated. Apart from melamine-urea and phenolic-resorcinol adhesives, one-component-polyurethanes, emulsion isocyanate polymers and epoxies offer a wide range of possibilities. The contributions dealing with experimental and numerical investigations on static, cyclic and seismic behavior of structures clearly reveal the enhanced potential of modern timber construction for reliable and sustainable buildings and bridges of the new millennium. The book is structured in nine thematic areas, being I) Structures II) Mechanical Connections III) Glued Joints and Adhesives IV) Timber and Concrete/Cement/Polymer Composites V) Cyclic, Seismic Behavior VI) Hardwood, Modified Wood and Bamboo VII) Cross-Laminated Timber VIII) Properties and Testing of Wood IX) Glulam
