Course Outline
This course provides
the documentation to enable the use of a post-tension design spreadsheet program
for one-way concrete beam and slab and two-way concrete slab systems. Documentation
for the program includes: Program Scope, Design Assumptions, Design Methodology,
Program Limitations, Description of Input/Output, Hardware Requirements, Variable
List, Design Examples and Manual Calculation Checks. In addition, a copy of
the spreadsheet program is also made available.
This course includes a multiple choice quiz at the end.
Learning Objective
The propose of this course is to enable the user to develop a fundamental understanding of the design of post-tensioned concrete structures in order to make the use of the spreadsheet program both possible and practical.
Course Introduction
This course deals primarily with the design and computational aspects of post-tensioned concrete structures. For general design philosophy and analysis of post-tensioned concrete, the reader should refer to PDHonline Course s127: General Overview of Post-Tensioned Concrete Design.
Course Content
This spreadsheet program provides for the design and analysis of post-tensioned concrete one-way beam and slab systems and two-way flat plate slab systems. The program is divided into three separate screens, which correspond to the three major areas of concern in the design of a post-tensioned member. These categories are: Service Stress Analysis, Ultimate Moment Strength and Ultimate Beam Shear Analysis. This last category is further subdivided into a supplemental screen for the design and analysis of combined Ultimate Beam Shear and Torsion. Although the Service Stress and Ultimate Moment Strength portions of the program are capable of analyzing both one-way beams and slabs and two-way flat plates, the Ultimate Shear and Shear/Torsion portions of the program are intended for the analysis of one-way beams only. All ultimate strength analysis portions of the program are intended for unbonded post-tensioned systems only.
This program is
not based on the latest version of the ACI 318 Code but can be modified as required
to update per the latest edition of the Code. The results of this program have
been compared to other proprietary software that is available on the market
place, such as ADAPT, with accurate correlations resulting.
In this lesson, you
need to
The above spreadsheet program and User's
Manual can be downloaded and be printed free of charge. Choose any of the formats
below to start downloading:
Download POST-TENSION.xls (a spreadsheet program, 55 KB)
Download the zipped User's Manual of POST-TENSION.xls (a zip file, 19.8 MB - choose this format for faster download)
Download User's Manual of POST-TENSION.xls in PDF format (a pdf file, 20.3 MB, 57 pages - Because of the large size, it may take some time to load this file into Acrobat Reader. It is recommended to download the zipped manual and unzip it using WinZip.)
Course Summary
This course provides the user with a fundamental understanding of post-tensioned concrete design to enable the use of a spreadsheet program. The program provides for the ultimate strength and service stress design and analysis of one-way beam and slab and two-way flat plate systems.
Access to the separate
program used to analysis post-tensioning losses including friction and wedge
set used in conjunction with the spreadsheet program can be made possible by
contacting the author of this course.
