PLEASE NOTE: THE SYLLABUS IS SUBJECT TO CHANGE, DEPENDING ON HOW QUICKLY WE CAN COVER THE MATERIAL. PLEASE CHECK FOR CHANGES IN HOMEWORK ASSIGNMENT DUE DATES BEFORE WORKING YOUR NEXT PROBLEMS.
NOTE ALSO THAT AS THE SYLLABUS CHANGES (AND IT ALWAYS DOES), YOU WILL HAVE TO RELOAD IT, OR IT WILL GO TO YOUR COMPUTER’S CACHE AND GIVE YOU THE ONE YOU LOOKED AT LAST WEEK , I.E. THE OLD OUT-OF-DATE ONE.

NOTE: My office hours as listed here are suspended on days before a major exam, giving me time to make it out. Please do not wait until the day before a major exam for help. Plan to see me earlier in the week.
Teaching Associate: None
HELP DESK – None??? Have to see if they hired any. During regular semesters when there are more students, tutoring is done by 5 graduate students located in the Old Civil Engineering Building Room 023. Go down the stairs to the basement, turn left, it is down the hall on your right. 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.
Click here for their hours (not yet posted for Summer 2017), which run from 8 AM to 7 PM except on Friday.

9781133943891 (13 digit)
Note that less inexpensive International Editions are often available, but they are sometimes in all SI units, whereas in the U.S. edition, all example problems and half of the homework problems are U.S. customary units. For the 5th edition, I have found that an International edition is available the same as ours.
|Texas A&M University Bookstore Fill in the Department, Course, and section number|
|CampusBooks4Less.com – Turns out that their International edition last semester was identical to the U.S. edition that we are using. I just bought it. Cost ~ $43 new, paperback, no color. Check the ISBN number carefully, and be ready to return it. These can be a gamble.|
ORDER EARLY! Here is where a text I bought has been. Around the world in 30 days.
Note that the internet is a thieves paradise. If they won’t show you the cover, check the ISBN number carefully.
Theory of Structures. (3-0). Credit 3. Structural engineering—functions of structures, design loads, reactions and force systems; analysis of statically determinate and indeterminate structures including beams, trusses and arches; energy methods of determining deflections of structures; influence lines and criteria for moving loads; analysis of statically indeterminate structures including continuous beams and frames. Prerequisites: CVEN 302 or registration therein; CVEN 305.
- To introduce students to the general behavior of statically determinate and indeterminate structures and determination of forces therein. Construction of influence lines. Determination of load and load placement on structures. Use of available computer programs for analyzing statically indeterminate structures.
Learning Outcomes – This course emphasizes the following ABET Learning Outcomes. Note that the letters refer to those used by ABET.
(a) Ability to apply knowledge of basic mathematics, science, and engineering.
To take CVEN 345, you must have received a passing grade (no D’s, F’s or I’s) in CVEN 305 and be registered or have already passed CVEN 302.
- Graded major exams (Quiz A, Quiz B, Final Exam = 3 @ 30% each) for 90% of final grade.
- Graded homework assignments, Readiness Assessment Tests (RATs), Class Participation, Attendance, Projects (all of equal value) = 10% of final grade.
- General Information Regarding Format for Exams, Quizzes, and Homework
- Where to get help for 345 (not in summer)
- Grading – All homework and quizzes will be graded using Beason’s Qualitative Grading Rubric.

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.
