The subject of calculus of variations is to find optimal solutions to engineering problems where the optimum may be a certain quantity, a shape, or a function. Applied Calculus of Variations for Engineers addresses this very important mathematical area applicable to many engineering disciplines. Its unique, application-oriented approach sets it apart from the theoretical treatises of most texts. It is aimed at enhancing the engineer’s understanding of the topic as well as aiding in the application of the concepts in a variety of engineering disciplines.
The first part of the book presents the fundamental variational problem and its solution via the Euler–Lagrange equation. It also discusses variational problems subject to constraints, the inverse problem of variational calculus, and the direct solution techniques of variational problems, such as the Ritz, Galerkin, and Kantorovich methods. With an emphasis on applications, the second part details the geodesic concept of differential geometry and its extensions to higher order spaces. It covers the variational origin of natural splines and the variational formulation of B-splines under various constraints. This section also focuses on analytic and computational mechanics, explaining classical mechanical problems and Lagrange’s equations of motion.

The thoery of calculus of variations is somewhat complicated, It can be
rarely used in the civil engineering design process. But for some civil engineer dedicated in the field of theoretical rearch such as finite element methods , it can be used sometimes. So I post this book with the hope that it can do some help for those few engineers.
Design for Water: Rainwater Harvesting, Stormwater Catchment, and Alternate Water Reuse
Design for Water: Rainwater Harvesting, Stormwater Catchment, and Alternate Water Reuse
Author(s): Heather Kinkade-Levario
Publisher: New Society Publishers
Date : 2007
Pages : 253
Format : pdf (high quality)
Language : English
ISBN-10 :
ISBN-13 : 9780865715806
Book Info:
In an era of dwindling resources, water is poised to become the new oil. The entire world now faces the reality of a decreasing supply of clean water. To avert a devastating shortage, we must not only look at alternate water sources for existing structures but must plan our new developments differently.
Design for Water is an accessible and clearly written guide to alternate water collection, with a focus on rainwater harvesting in the urban environment.
The book:
* Outlines the process of water collection from multiple sources-landscape, residential, commercial, industrial, school, park, and municipal systems
* Provides numerous case studies
* Details the assembly and actual application of equipment
* Includes specific details, schematics, and references
All aspects of rainwater harvesting are outlined, including passive and active system setup, storage, storm water reuse, distribution, purification, analysis, and filtration. There is even a section on rainwater harvesting for wildlife.
In addition to rainwater, there are several affordable and accessible alternate sources, including cooling tower bleed-off water, air conditioning condensate, gray water, and fog collection. D esign for Water is geared to providing those making development decisions and guidelines with the information they need to set up passive harvesting techniques. The book will especially appeal to engineers, landscape architects, municipal decision-makers, developers, and landowners.

Bentley Rebar is a fully interactive reinforced concrete detailing and scheduling system, applicable to a wide range of concrete structures, from the simple to the very complex. The two-dimensional (2D) detailing process is simple and easy-to-learn, and not unlike traditional manual detailing procedures. Powerful tools link reinforcement shown in cross-section with details shown in plan and elevation, thereby extending the system into the third dimension. Within a 3D design file, these “2½D” features combine with MicroStation’s modeling tools to produce 3D models of your reinforcement, eliminating many hundreds of hours normally required to complete such a task.
Installed in Bentley MicroStation (SELECTseries 2) V8i 08.11.07.443

i looks for document reports/papers about finite element application to shell reinforced concrete. it's used by SAP2000 application, very interested :blush:
1. "Optimum design of reinforced concrete shells and slabs” by Troels Brondum -Nielsen,Technical University of Denmark, Report NR.R 1974 or
2. "Design of Concrete Slabs for Transverse Shear”, Peter Marti, ACI Structural Journal, March-April 1990
i believe for a report listed above is old and unpublish widely, so it's imposible the others to reach and learn??

Metallic Materials compares and contrasts the corrosion resistance of wrought stainless steel and high nickel alloys and explores recent advances in the production of exotic metals. It emphasizes the physical and mechanical properties, corrosion resistance, workability and cost of various metals. The author analyzes the physical and mechanical properties of metals, defines relevant terminology, describes the various forms of corrosion to which metals may be susceptible, examines wrought ferrous metals, alloys, and typical applications, and covers wrought nickel and high nickel alloys. This is a handy reference for the busy engineer and student in corrosion, materials, chemical, mechanical, civil, design, process, metallurgical, manufacturing, and industrial engineering.

A balanced mechanics-materials approach and coverage of the latest developments in biomaterials and electronic materials, the new edition of this popular text is the most thorough and modern book available for upper-level undergraduate courses on the mechanical behavior of materials. To ensure that the student gains a thorough understanding the authors present the fundamental mechanisms that operate at micro- and nano-meter level across a wide-range of materials, in a way that is mathematically simple and requires no extensive knowledge of materials. This integrated approach provides a conceptual presentation that shows how the microstructure of a material controls its mechanical behavior, and this is reinforced through extensive use of micrographs and illustrations. New worked examples and exercises help the student test their understanding.
