# Presents a unified treatment of rigid and flexible multibody dynamics
# Includes analysis software
# Advances in computational tools in multibody dynamics are making finite element based formulations increasingly popular
# Many of the multibody dynamics books on the market focus on classical formulations based on rigid body dynamics, floating frame of reference, and modal approximations
The author developed this text over many years, teaching graduate courses in advanced dynamics and flexible multibody dynamics at the Daniel Guggenheim School of Aerospace Engineering of the Georgia Institute of Technology.
The book presents a unified treatment of rigid body dynamics, analytical dynamics, constrained dynamics, and flexible multibody dynamics. A comprehensive review of numerical tools used to enforce both holonomic and nonholonomic constraints is presented. Advanced topics such as Maggi’s, index-1, null space, and Udwadia and Kalaba’s formulations are presented because of their fundamental importance in multibody dynamics. Methodologies for the parameterization of rotation and motion are discussed and contrasted. Geometrically exact beams and shells formulations, which have become the standard in flexible multibody dynamics, are presented and numerical aspects of their finite element implementation detailed. Methodologies for the direct solution of the index-3 differential-algebraic equations characteristic of constrained multibody systems are presented. It is shown that with the help of proper scaling procedures, such equations are not more difficult to integrate than ordinary differential equations.
This book is illustrated with numerous examples and should prove valuable to both students and researchers in the fields of rigid and flexible multibody dynamics.

I just downloaded and installed Seismosignal on my pc to do some small checks in AK Chopra.
The Acceleration-Time graph is coming out as a straight line!!!
Worse of it still, the help menu is clickable but brings nothing up. At least i would have referred it. Any help. Its version 3.3 i guess.
Regards
The Acceleration time graph should not be a straight line!!!!!
I first tried the same data as jacs127 used in his screen shot in vain. All the other graphs are similar to his but only Accn-Time is not. Mine is just at zero!!!!
The Accn -Time graph under time series is not right for me. The one under fourier and power spectra is correct. I think both should correlate.

1.Key Features
A unique and inspirational guide to shopping centre design
An international range of full colour illustrations explore the key contemporary issues in retail design and planning
Packed with essential technical information and design detail
2.Description
Shopping centers have become the most common of shopping environments and have influenced the make-up of cities around the world. However, in recent years, the enclosed ";mall"; has evolved and diversified with new types of retail environments that were developed to better suit their locale and meet public expectation.
This design guide has over 600 illustrations that present the core values and considerations that make a successful retail center: location, catchment user needs, as well as access and layout. Covering everything from site master planning to the essentials of public facilities and the technical systems, this is essential reading for architects of contemporary shopping centers.
A series of international examples showcasing different types of shopping environments are included to cover the wide range of designs that have occurred in recent years. From the ";out of town"; mall to retail parks and mixed use town center developments, the best of contemporary design is illustrated to provide both practical information and inspiration.
3.Readership
Professional architects. Student architects, professionals and students in related fields such as urban design, planning; retail managers, facility managers and retail companies.
4.Quotes
“What distinguishes this book is its depth and historical sweep, instructive detail and lavish illustrations, topicality and abundance of case studies. The author, an architect and urban designer, writes with the authority and clarity of a professional who has to explain how things work to politicians and the public. He has the knack of turning what could easily baffle and bore readers with technical information into readable, comprehensible, useful detail. Wherever it may land, the book should appeal to all the design disciplines involved in creating a shopping center. Developer clients would find it a useful read as well.”

Publication of this edition has been sponsored by the Cast Iron Soil Pipe Institute to provide a reference book which fully meets the needs of those requiring information on the industry’s products. It was compiled and edited by the Technical Advisory Group of the Cast Iron Soil Pipe Institute, and the content has benefited from the collaborative effort of its members and their experience in the manufacture and application of cast iron soil pipe and fittings. This publication is subject to periodic revision, and the latest edition may be obtained from the Cast Iron Soil Pipe Institute.
The Cast Iron Soil Pipe and Fittings Handbook has been published to present useful information of technical and general nature on the subject of cast iron soil pipe. In recent years, the volume and diversity of this information has increased, primarily as a result of changes in the industry and its products. Technological changes in foundry practice have been introduced; conventional products have been improved; new products and new jointing methods have been developed, together with new installation procedures. Further, product standards and specifications have been revised. A handbook was considered an appropriate medium for outlining these developments and providing useful information.

Cable-Based Retrofit of Steel Building Floors to Prevent Progressive Collapse
by Samuel Tan, Albolhassan Astaneh-Asl
Abstract
The project summarized here was the third phase of a three-phase research and development project. Phases 1 and 2 focused on new buildings while the third phase, discussed in this report, was primarily for the retrofit of existing buildings. The two main objectives of this study were:
1. To establish inherent strength of typical floor framing systems in steel structures to resist progressive collapse in the event of removal of a column by a bomb blast and;
2. To develop and test cable-based mechanisms that can be used to prevent progressive collapse in the event of removal of a façade column.
The test specimen was a single-story steel frame with composite floor slab. The specimen measured approximately 60 ft (20 m) by 20 ft (6 m) by 6.5 ft (2 m) tall. The steel floor beams were supported by ten wide-flange columns. The beam-to-column connections in the test area were typical shear tabs (single plates). Two columns in the middle span of the specimen were designed and constructed as drop columns. These drop columns terminated 36 inches (1 m) above the laboratory floor. During testing, the support of drop columns could be removed and a vertical downward displacement could be imposed upon these drop columns. Subsequently, the floor displaced downward under gravity load and developed tensile forces due to catenary action. This project investigated the capacity of an existing steel frame structure, retrofitted with high strength steel cables, to resist progressive collapse by developing catenary action in its floor framing members.
Three tests were conducted on the specimen. In the first test, the specimen represented a typical steel structure without any mechanism to prevent progressive collapse. The second and third tests represented the structure after two steel cables were placed on the web of the façade beams, one at each corner of web-flange intersection as a retrofit measure. The cables were anchored to the last column on each end of the floor. The columns transferred the tension force of the cable to the floor framing and the floor slab. The cables acting in a catenary action mode added to the strength of the system and prevented progressive collapse of the floor after removal of the middle column. The mechanisms performed well in the tests and proved to be very efficient and economical in preventing progressive collapse of the tested specimen.
