HELP DESK HOURS for Spring 2018
Located in the old pi R^2 room, ground floor of the Dwight Look building (formerly the CE/TTI 8 story building). Has sign on desk: Help Desk CVEN Mechanics. They run a full-blown help desk for our class. All of them are good in tutoring you the material in CVEN 345. Just ask whoever is there for help. Click here for the TA help desk schedule, who will be covering each time slot and hours of operation. Email me if they change this at Lowery@tamu.edu. (Not yet posted for Summer 2018), which run from 8 AM to 7 PM except on Friday.

2015 5th edition ISBN Numbers
Note that less expensive International Editions are available for almost all books. For the Kassimali 345 5th edition, I have found that most of the International editions are the same as ours except for the numbering of the homework problems.

| Texas A&M University Bookstore Fill in the Department, Course, and section number |
|
AbeBooks.com – NOTE! The text and the problems in the international edition are the same as the US edition. However, the problem numbers have been changed. Thus you would have to get with someone who has a real text to see what problem number is assigned. I think they are all in there, but the problems will have a different number. Also, check the ISBN number carefully, and be ready to return it, but AbeBooks is a good company. I have bought a ton of books from them. A student sent me this list of the problem numbers for the US vs. the international edition, but I don’t know if it’s accurate, so no guarantee! Check with someone who has a real book before working your homework problems. |

Objectives and Outcomes:
Benefits of taking the course: Students will analyze and evaluate both determinate and indeterminate structural systems. They will be able to describe the structural engineering profession and demonstrate the role of structural analysis within the context of structural engineering design and decision-making
Course Objectives:
This course focuses on the following major learning objectives:
(1) To develop an understanding of the basic principles of structural analysis and be able to explain them,
(2) To determine and analyze models of applied loads on structures
(3) To utilize various exact methods (both classical and matrix-based) of analysis of beams, trusses, and rigid frames to determine the response of both determinate and indeterminate structures
(4) To utilize various approximate methods of analysis of beams, trusses, and rigid frames to determine the response of both determinate and indeterminate structures
(5) To apply the method of virtual work in determining deflections of structures,
(6) To develop and utilize influence lines of structures,
(7) To evaluate the response of various structural systems (both determinate and indeterminate) under a range of demands, such as applied loads, support motions, and temperature changes
(8) To demonstrate the role of structural analysis within the context of structural engineering design and decision-making.
ABET Outcomes Addressed
- Ability to apply knowledge of mathematics through differential equations, science (including physics, chemistry, and one additional area of science), and engineering
- Ability to formulate and solve civil engineering problems
- Understanding of professional and ethical responsibility
- Recognition of the need for, and an ability to engage in, life-long learning
- Ability to use modern tools, techniques, and computation methods necessary for civil engineering practice
The correct time (to the nanosecond)
Course Schedule: Please note that the course syllabus will be revised throughout the semester. Please do not work problems very far ahead of the date due. Some may be dropped, others added that are better (in my opinion).

READ: How to construct and use influence lines Notes: The first influence lines are to be generated by statics. All later influence lines can be worked by statics or by Mueller-Breslau if it is to your advantage. All numeric values are required on all influence lines for statically determinate structures unless otherwise noted. Numeric values on statically indeterminate structures are not required – only the general shape of the influence line. Highly recommended: Muller-Breslau Principle, Use of Influence Lines. |
