Section Description

Analysis of statically determinate beams, frames, and trusses; expected loads, reactions; influence lines; moving loads; geometric methods for displacement calculations; introduction to matrix analysis for trusses. COURSE LEARNING OBJECTIVES: 1. Identify different types of loads and compute dead, live, wind, snow and earthquake loads on common structural systems (Ch1). 2. Further develop skills to (a) identify statical determinacy and stability of structures, (b) create idealized models and (c) apply equations of equilibrium to compute support reactions (Ch2). 3. Analyze statically determinate trusses using the method of joints and the method of sections (Ch3). 4. Design and analyze a statically determinate bridge using the Bridge Designer software to withstand a given load for a given span, then optimize the design to minimize the cost (Design Project). 5. Compute internal forces at specified locations of a structure and construct shear and moment diagrams for beams and frames (Ch4). 6. Analyze cables and arches (Ch5). 7. Construct influence lines for beams, frames and trusses (Ch6). 8. Analyze statically indeterminate trusses and frames using approximate methods (Ch7). 9. Compute deflection of beams using second order differential equation, moment area theorem and energy method (virtual work) (Ch8 & Ch9). 10. Acquire the basic understanding to analyze statically indeterminate structures using the force method (Ch10). COURSE OUTLINE 1. Types of structures and introduction to loads and design codes 2.

Internal loadings: shear and moment diagrams for beams and frames 5. Cables and arches 6. Influence lines for statically determinate structure 7. Approximate analysis of statically indeterminate (SI) structures 8. Deflections: using second order differential equation, moment area theorems and energy method (virtual work) 9. Introduction to force methods 10. Structural modeling and computer analysis (group project)

Section Expectation

This course combines lecture and discussion formats. Students should expect to spend 7-9 hours a week on coursework outside of class, with additional time for group projects and presentations. Students will be led through a review of chapter reading assignments and two to three relevant examples problems in each lecture period with opportunities to pause, reflect, and comment on what they’ve learned. Physical models and simulations will be used to demonstrate key concepts. New topics will be grounded in real world examples throughout. Make-up exams will be given at the discretion of the instructor. An appropriate, valid documentation of absence will be required for consideration of a make-up exam. It is strongly encouraged to obtain prior permission from the instructor. Examples of valid reasons are; injury or illness that is too severe or contagious for the student to attend, participation in a university authorized activity, death or major illness in a student’s immediate family, time conflicts with other courses, or important travel plans. Homework assignments will be assigned weekly in class and will be posted on Bb. They should strictly follow the homework format which is posted on Blackboard under “HW” tab and will be collected at the beginning of class. Those who come late to the class must submit their assignments before taking a seat, or else will be considered as late. Only one late homework assignment per student (except the ones that are due prior to the exams) will be accepted but, no make-up quizzes or RATs will be given without a valid reason (listed above).
