Great attention is devoted, for example in Europe and Asia, to the development of regional airports, both to improve the congestion situation at the main hubs and to help the economic development of some decentralized areas. In this context, more actors can play an important role, as airport planners, air companies (including low-cost companies) and users (passengers and/or freight) that affect demand levels at airports through their travel choices. Furthermore, an efficient use of resources suggests we consider the role of existing regional airports before starting the building of new airports. In the USA more studies concern the analysis of airport systems (as in the Los Angeles area) in order to verify the role of each airport and the effects on the main, congested hub(s). In this light this book gives an overview of the main aspects of the potential development of regional airports, particularly the economic aspects, the role of the low-cost companies, demand modelling, the airport, airline and access mode of choices; and the relationships between hub capacity constraints and regional airports growth. Examples of different airports throughout the world are also presented as test cases with respect to the various aspects.

Author: Alan Jefferis, David A. Madsen and David P. Madsen | Size: 87 MB | Format:PDF | Publisher: Delmar Cengage Learning | Year: 2010 | pages: 1127 | ISBN: 1435481623
ARCHITECTURAL DRAFTING AND DESIGN, 6E is an ideal book for all architectural drafters and CAD operators, whether beginning, intermediate, or advanced. An important feature of this best-seller is its step-by-step instructions for the design and layout of each type of drawing associated with a complete set of architectural plans, with projects that can be completed using either CAD or manual drawing methods. The basics of residential design, commercial drafting, basic materials used for construction, common construction methods, and drawings typically associated with commercial construction are all covered in this comprehensive book, which is written to meet the most recent editions of IRC and IBC. Readers will be introduced to the various types of projects that a designer or architect is likely to complete during the actual design process and will gain the knowledge needed to complete the drawings required by most municipalities to obtain a building permit for a single-family residence.

Considerations in the Design and Analysis of an ASME Section VIII, Div. 2 Reactor Support Skirt
Author: Dennis K. Williams, Trevor G. Seipp | Size: 402 KB | Format:PDF
This paper describes the considerations employed in the finite element analysis of a relatively “short” support skirt on a hydrocarbon reactor vessel. The analysis is accomplished in accordance with ASME B&PV Code, Section VIII, Division 2 alternate rules in conjunction with the guidelines outlined in WRC Bulletin 429. This provides a sound basis for the classification of the calculated stress intensities. The support skirt is capable of sustaining the deadweight load in addition to resisting the effects of thermal displacements, wind loadings, overturning moments from external piping loads on the attached hydrocarbon reactor vessel, and friction between the skirt base plate and concrete foundation. The displacement and thermal boundary conditions are well defined and discussed in detail. The effects of multiple scenarios for the displacement boundary conditions are examined. The skirt design also employs a hot-box arrangement whereby the primary mode of heat transfer is by radiation. A discussion of the two-part analysis is included and details the interaction between the heat transfer analysis and the subsequent structural analysis. The heat transfer finite element analysis is utilized to determine the temperatures throughout the bottom of the vessel shell and head, as well as the integrally attached support skirt. Of prime importance during the analysis is the axial thermal gradient present in the skirt from the base plate up to and slightly beyond the skirt-to-shell junction. While the geometry of the subject vessel and skirt is best described as axisymmetric, the imposed loadings are a mixture of axisymmetric and nonaxisymmetric. This combination lends itself to the judicious selection and utilization of the harmonic finite element and properly chosen Fourier series representation of the applied loads. Comparison of the thermally induced axial stress gradient results from the FEA to those obtained by the closed form beam-on-elastic-foundation are also tendered and discussed. Finally, recommendations are included for the design and analysis of critical support skirts for large, heavy-wall vessels.
The Second part of this thread i am sharing Hot-box Finite Element Analysis report using ANSYS with helping this paper, and i am sure that will help this kind of analysis.
