The use of composite materials for repair and rehabilitation of corroded steel pipes has
been increasingly growing in the oil and gas industry. However, there exists a noticeable
gap in the literature on the long term performance of composite repaired pipes, especially
those subjected to large internal pressure magnitudes. This work is an attempt toward
filing the gap by gaining a better understanding of the effects of environmental
conditions on the long term performance of composite repaired pipes subjected to large
internal pressures. Finite element method (FEM) is used to simulate typical composite
warp-repaired gouged steel pipes, conditioned in various environments and subsequently
subjected to internal pressure. The influence of the resulting degradation in composite’s
mechanical properties on the performance of the system was evaluated. To validate the
results, an experimental program was designed and carried out. Repaired specimens
were conditioned in an environmental chamber under certain thermal and moisture conditions;
then, the specimens were tested to failure subject to internal pressure. Good correlation
was obtained after fine tuning of FEM model’s material data through the use of
the experimentally obtained data.

It provides all the implementation details of GEP so that anyone with elementary programming skills will be able to implement it themselves. The book includes a self-contained introduction to this new exciting field of computational intelligence. This second edition has been revised and extended with five new chapters.
From the Back Cover
Cândida Ferreira thoroughly describes the basic ideas of gene expression programming (GEP) and numerous modifications to this powerful new algorithm. This monograph provides all the implementation details of GEP so that anyone with elementary programming skills will be able to implement it themselves. The book also includes a self-contained introduction to this new exciting field of computational intelligence, including several new algorithms for decision tree induction, data mining, classifier systems, function finding, polynomial induction, times series prediction, evolution of linking functions, automatically defined functions, parameter optimization, logic synthesis, combinatorial optimization, and complete neural network induction. The book also discusses some important and controversial evolutionary topics that might be refreshing to both evolutionary computer scientists and biologists. This second edition has been substantially revised and extended with five new chapters, including a new chapter describing two new algorithms for inducing decision trees with nominal and numeric/mixed attributes.

Knowledge of the behavior of soil mechanics is essential for forecasting the internal displacements and actions of any construction. This book, although theoretical at first glance, also offers a more practical scope, giving readers adequate tools to plan geotechnical projects correctly.

Building Structures Illustrated: Patterns, Systems, and Design
Author: Francis D. K. Ching, Barry S. Onouye, Douglas Zuberbuhler | Size: 7.2 MB | Format:PDF | Quality:Unspecified | Publisher: Wiley | Year: 2009 | pages: 322 | ISBN: 9780470187852
Francis D.K.Ching brings his trademark presentation to the structural design studio with this major new work co-authored by Barry Onouye and Douglas Zuberbuhler.
Taking a new approach to strucural design, Ching and his co-authors show how structural systems of a building -- as an integrated assembly of elements with pattern, proportions, and scale -- are related to the essential aspects of architectural design: formal and spatial composition, program fit, coordination with other building systems such as enclosure and mechanical systems, code compliance, etc.
No other work by Francis D.K. Ching brings together so many aspects of architectural design as an integrated reference. Designers, builders, and students alike will gain a new understanding of structural principles and planning, without the need for mathematics.
Using Ching's trademark presentation, Structural Patterns is illustrated throughout with line drawings to present the essential presence of structural systems in buildings, but also helps the reader make informed decisions for architectural design

This manual is published in two volumes. Volume 1 includes design and analysis for columns, flexure, footings, seismic, shear, and two new chapters on deflection and strut-and-tie in accordance with ACI 318-11. Information is presented in three sections: Explanatory Material, Design Examples, and Design Aids. The Introduction of each chapter includes explanatory material that provides the engineer with concise background of the subject. The Design Examples illustrate the use of the Design Aids, which are tables and graphs intended to eliminate routine and repetitious calculations. Volume 2 (available separately) includes design and analysis for anchorage to concrete.

Progressive collapse resistance of existing building structures against sudden column loss may be increased
with adequate supply of steel braces. A performance-based design approach for retrofitting regular building
frames with steel braces is proposed in this study. The retrofit design approach is developed from the pseudostatic
response analysis of an idealized elastic–plastic, single degree-of-freedom system. Analytical relationship
between the increment of collapse resistance and structural characteristics is derived to determine the design
strength and stiffness of added braces. Accuracy of the proposed approach is verified with incremental dynamic
analysis. Also, its application to multi-story buildings is demonstrated with three frame models. Conservative
performance is obtained with the design approach, especially for a larger resistance increment. An iterative
modification technique is suggested to refine the retrofit design and only a few nonlinear static iterations are
required for convergence. Nonlinear dynamic analysis results indicate that the column-loss response of the
braced frames is approximated to the performance target and thus the proposed retrofit design approach is
feasible for practical applications.
