Course objectives, syllabus, books, video lectures, pre-requisites
Objectives
- To learn fundamentals of structural analysis.
- To develop simple computer programs to perform structural analysis.
After finishing this course, you will
- know how to analyse simple structures by hand
- know how to use computer programming to analyze large structural systems
- understand linear analysis of structures
Syllabus
- Review of some concepts from Mechanics of Solids.
- Degrees of indeterminacy (static and kinematic).
- Types and analysis of trusses, cables, arches, beams, columns and frames.
- Specific methods to be covered: moment area theorem; conjugate beam method; principle of virtual work; energy method; Castigliano’s theorems; unit-load and unit-displacement theorems; reciprocal theorems; Betti's and Maxwell's theorem; method of consistent deformations; slope-deflection method; displacement based methods; moment distribution method; column analogy method
- Influence lines; Muller-Breslau's principle
- Matrix method of analysis (if time permits)
Text Book
- Structural Analysis 5th edition - Devdas Menon, Narosa Publishing House Pvt. Ltd.
Reference Books
- Structural Analysis - R.C. Hibbeler, Prentice Hall.
- Structural Analysis - Aslam Kassimali, Cengage Learning.
- Matrix Structural Analysis - W. McGuire, R.H. Gallagher, R.D. Ziemian (available here: http://www.mastan2.com/textbook.html).
Software
- Simple computer codes for analysis will be developed in Python.
- SAP2000 will be used for more complicated analyses.
- Another useful software tool is MASTAN2 (http://www.mastan2.com/)
Video lectures
Pre-requisites
- Curiosity about how structural systems (buildings, bridges, dams, etc.) are designed – analysis is essential for design.
- Good background of solid mechanics and any programming language.
Course Policies
Etiquette
- Please be considerate about everyone's time.
- In all emails pertaining to this course, please have "CE302" in the subject line.
- (note that there is no space or hyphen or anything between CE and 302)
Cheating
Cheating (in assignments/quizzes/exams) is unacceptable. It is expected that this will never happen and everyone will uphold the honor code.
Late submissions
All delays beyond the defined deadlines will attract reduction in marks as per the following curve. The reduction factor, \(R\) will be multiplied to the obtained marks. Mathematically, it is given by: \(R = \exp(-D^2)\), where \(D\) is the total delay in days (will be counted hourly, i.e. fractional days are possible).
Grading
Following will be the weightage of different components of assessment
Component | Weightage |
---|---|
Homework assignments | 30% |
Spot quizzes | 20% |
Class participation | 10% |
Midsem exam | 20% |
Endsem exam | 20% |
Extra credit
Earn up to 20% extra credit by creating problem-solving videos.
- Choose a problem (to be shown to the instructor for confirmation)
- Create a detailed solution.
- Create a video of 2-3 minutes explaining the detailed solution.
- Quality of the video should be good so that it can be shared online (e.g. on youtube).
- This activity can be taken up in groups of up to 2 persons.
- Each video can earn up to 2% extra credit subject to the overall 20% limit (both group members to get the same credit).
- Each video will be rated by rest of the class. Grading of the video will include these ratings.
- Last date to submit videos: 25 November 2023
Modes of formal assessment
- Assignments will involve detailed analysis and hands-on questions.
- Expect one assignment per week.
- Spot quizzes will primarily be objective type, primarily based on concepts and codes. Expect one quiz per week.
- Exam will primarily be subjective type. It may be in-class or take-home.
Emphasis on self-learning
It is important to develop the habit of self-learning. A number of reading assignments and self-exercises will be given during the course. These will not be formally graded and it will be expected that students will go through them on a regular basis on their own.
