Credit Hours:

3

Instructor:

Dr. Shirley Dyke

Learning Objective:

By the end of the course, you will be able to:

  1. Model dynamic systems and describe how they respond to various loadings.
  2. Determine the dynamic characteristics of a variety of linear structural systems.
  3. Obtain and solve the equations of motion for a dynamic system modeled as a linear system

Description:

Analysis of structural members and systems subject to dynamic loads such as wind and earthquake loads; basic theory for single-degree-of-freedom and multi-degree-of-freedom analytical models of civil engineering structures; free vibration, harmonic and transient excitation, foundation motion, response spectrum, frequency domain analysis, Lagrange's equation, modal analysis, lumped parameter methods, computer methods.

Topics Covered:

Single Degree of Freedom (SDOF) Systems; Multi Degree of Freedom (MDOF) Systems; Distributed Parameter Systems

Prerequisites:

  • Able to solve differential equations
  • Understanding of matrix operations and eigensolutions

Grading:

This course will be graded based on the following criteria:

Assessment Type Description % of Final Grade
Homework Homework assignments will include both textbook problems and computer (MATLAB) assignments designed to support learning and assess the student’s understanding of the material. Homework must be submitted to Gradescope by 11:59pm on the due date unless otherwise noted. Homework should be clear and neat; there is no requirement to use special paper. Late homework will not be accepted. 9 assignments are planned during the course. 20%
Quizzes Short quizzes will be used to assess the student’s understanding of the material. These quizzes will be comprehensive. After each quiz is graded, feedback will be provided to advise on the material that is relevant for exam preparation. Quizzes will be timed (students will typically have 1 hour for each quiz). Students will have one attempt to complete each quiz. Quizzes should be completed individually but students may reference notes, homeworks, videos, the textbook, and other reference books. 6 quizzes are planned during the course 20%
Exam I Exam I will assess the student’s achievement of the learning objectives in Section 1 of the course, SDOF Systems. 20%
Exam II Exam II will assess the student’s achievement of the learning objectives in Section 2 of the course, MDOF Systems. Knowledge of previous material (Section 1) is expected. 20%
Exam III Exam III will assess the student’s achievement of the learning objectives in Section 3 of the course, Distributed Parameter Systems. Knowledge of previous material (Sections 1 and 2) is expected. 20%

Exams:

All exams are 60 min. One 8.5 x 11” sized paper with writing on both sides may be used during exams. Calculators may be used. No other materials are allowed. Cell phones and smart watches of all types must be stowed away during all exams and quizzes. At the time of the exam, you will be required to join a web conference. The date/time for each exam as well as other details about logging in to the web conference will be announced prior to the exam. Each exam section will open in Brightspace (under the corresponding Section) when it is time to take the exam. Exams will be uploaded to Gradescope for grading at the end of the period.

Textbooks:

Official textbook information is now listed in the Schedule of Classes. NOTE: Textbook information is subject to be changed at any time at the discretion of the faculty member. If you have questions or concerns please contact the academic department.

Additional Tools/Technologies:

  • Use of MATLAB/SIMULINK will be expected to complete the computer simulations assigned as part of certain homework assignments. Any version of MATLAB/SIMULINK will be suitable for these simulations. OCTAVE is allowed, although help cannot be guaranteed; MATHCAD is not acceptable for this course.
