Design of Anchor Reinforcement in Concrete Pedestals According Appendix D of the ACI 318-05
Author: Widianto, Chandu Patel, and Jerry Owen | Size: 1.6 MB | Format:rar | Quality:Unspecified | Publisher: http://www.excelcalcs.com/ | Year: 21 Aug 2013 | pages: 3
ABSTRACT
Even though the Appendix D of the ACI 318-05 permits the use of supplementary
reinforcement to restrain concrete breakout, it does not provide specific guidelines in
designing such reinforcement. This paper presents a method for designing anchor
reinforcement in concrete pedestals, where un-reinforced concrete is insufficient to resist
anchor forces. Anchor reinforcement consists of longitudinal rebar and ties to carry
anchor tension forces and shear forces, respectively. The Strut-and-Tie Model is
proposed to analyze shear force transfer from anchors to pedestal and to design the
required amount of shear reinforcement. A proposed design procedure is illustrated in an
example problem

Advance Concrete software for concrete design and detailing is built on the AutoCAD platform. Work with easy-to-use, comprehensive tools to help accelerate more accurate modeling and automate the creation of construction drawings and deliverables. Interoperability with Revit software supports a more connected Building Information Modeling (BIM) workflow.
Reinforcement modeling and detailing
Use a variety of tools to reinforce structural elements, including cast-in-place concrete, precast concrete, and special construction elements.
•Detail bars and meshes freely, directly on 2D drawings, as Advance Concrete creates and maintains a 3D model
•Select from a library of predefined bar shapes
•Assign parametric reinforcement attributes for each object (beams, columns, openings)
•Automate the placement of reinforcement bars and keep drawings up-to-date when models are modified
•Automatically optimize mesh and bent mesh reinforcements
•Create and visualize 3D reinforcement cages, and check clashes more easily

Computational optimization methods have matured over the last few years due to extensive research by applied mathematicians and engineers. These methods have been applied to many practical applications. Several general-purpose optimization programs and programs for specific engineering applications have become available to solve particular optimization problems. Written by leading researchers in the field of optimization, this highly readable book covers state-of-the-art computational algorithms as well as applications of optimization to structural and mechanical systems. Formulations of the problems and numerical solutions are presented, and topics requiring further research are also suggested.

Math for Wastewater Treatment Operators, Grades 1 & 2:
A Guide to Preparing for Wastewater Treatment Operator Certification Exams
Author: John Giorgi | Size: 7 MB | Format:PDF | Quality:Unspecified | Publisher: American Waterworks Association | Year: 2009 | Pages: 125 | ISBN: 1583215875, 9781583215876
This new book was written to provide students and operators with examples of a variety of different problems that will be encountered both on the job and for Grades 1 & 2 certification exams. This book is divided into four main parts: a review of significant numbers and rounding; two chapters on math followed by practice tests; and appendices. Each problem is presented with easily followed steps and comments to facilitate understanding. Included after each grade level are tests to help you determine where your strengths or weaknesses are. Appendices contain conversion factors, wastewater treatment equations, chemistry tables, depth-to-diameter tables, and flow charts of wastewater treatment processes.

This first volume of a two-volume work presents the basic theoretical principles, methods of analysis in obtaining the solutions of beam-columns, and developments of theories of biaxially loaded beam-columns, and shows how these theories can be used in the solution of practical design problems. After presenting the basic theory the authors proceed to solutions of particular problems. The book discusses both refined and simplified design procedures, along with their limitations. It is left to the engineer to choose among them as he sees fit.
An unabridged J. Ross Publishing republication of the edition published by McGraw-Hill, Inc., New York, 1976, 536pp.
Key Features
-Discusses the complete theory of beam-columns from the most elementary to the most advanced state of development
-Presents various methods of solution that are best suited for different types of beam-column problems
-Provides numerical results in terms of tables, charts, and diagrams which furnish values of critical loads for various beam-column problems
