4. Syllabus Continued REQUIRED TEXT Notes for CE482 Elementary Structural Design by Dr. Hans H. Gesund Manual of Steel Construction, Load and Resistance Factor Design, 3 rd ed. American Institute of Steel Construction, Inc., 2001. COURSE DESCRIPTION Application of principles of solid mechanics to the design of steel, timber, and reinforced concrete members and structures. Emphasis is on basic ideas and their application to practical design of relatively simple structures according to the building codes.

5. Syllabus Continued GRADING POLICY Final averages will be computed as follows: Homework 24 % Midterm38 % Final Exam38 % Lower cut-offs for letter grades A, B, C, D will be 90, 80, 70, 60 respectively. However a slight upward adjustment of the grades may be made if, in the instructor’s opinion, the grades are too low. Homework assignments will be made throughout the semester. All homework must be submitted at the start of class on the assigned date. Late papers will not be accepted except in the case of extreme illness or officially sanctioned absence from campus. A grade of zero will be given for all unexcused absences from exams. Make-ups will be given only in cases of extreme illness or officially sanctioned absence from campus. Requests for make-up exams must be made before the scheduled test if possible.

6. Syllabus Continued ENGINEERING ETHICS It will be assumed that each student subscribes to a professional code of ethics that is the basis for their behavior in class. Any and every case where these ethics are violated will be dealt with according to the provisions in the Student Code. The minimum penalty specified by the Student Code for cheating is an E in the course.

9. We will spend the first few weeks on steel design. You will need to bring your Manual of Steel Construction and Lectures on Steel Design (first section of notes) to class each night. WARNING: EACH CLASS MEETING IS EQUIVALENT TO ABOUT ONE WEEK DURING THE REGULAR SEMESTER.

10. Introduction Before we can discuss each material, we must know what loads we are designing for and how to compare those loads to the strength of the material. Before we begin steel design we will discuss: Loads Design Philosophies

11. LOADS All loads fall into two main categories: Dead Loads Live Loads

12. Dead Loads Fixed position, gravity service loads (permanent) –Structural members –Plumbing –HVAC –Floor coverings –Suspended ceilings –Etc.

13. Live Loads Gravity loads acting when the structure is in service, but varying in magnitude and location. –Human occupants –Furniture –Stored goods –Vehicles –Environmental Loads

14. Environmental Loads Live loads but usually treated separately. They include: –Snow –Ice –Wind –Etc.

15. Building Code Live Loads Live loads are usually specified in Building Codes –We will reference the Kentucky Building Code (see the appendix to the steel section of the class notes) –A reduction to the live load is provided based on the probability that the entire building will not be subjected to the full combination of loads at one time.

17. Live Load Reduction Factor L = L o (0.25 +15/√A i ), A i in square feet L = L o (0.25 +4.57/√A i ), A i in square meters

18. Influence Area, A i Tributary area times 2 for beams Tributary area time 4 for columns Tributary area is the loaded area attributed to a member.

19. Calculating Tributary and Influence Areas modified from p. 2 notes – partial floor plan 10 ft 30 ft supporting girders beams 1 2 3 4

20. Example: Office Building Floor Plan Determine live loads on Beams B4 and B5, Girders G1 and G2, and Column B2 figure from p. A-11 notes

22. Design Philosophies LRFD – Load and Resistance Factor Design γ i = Load Factors Q i = Load Effect Ф = Resistance Factor R n = Nominal Strength or Resistance

23. Design Philosophies ASD – Allowable Stress Design Q i = Load Effect R n = Nominal Strength or Resistance F.S. = Factor of Safety

24. Typical Steel Stress-Strain Curve

25. Manual of Steel Construction LRFD Part 16 (Thumbnail ‘SPEC’) –Specification and Codes There are four different Specification listed on page 16-1. We will examine only the first, ‘LRFD Specification for Structural Steel Buildings’.

26. LRFD Specification for Structural Steel Buildings Table of Contents – p. 16.1-v The specification is divided into lettered chapters The chapters are followed by the Appendix then the Commentary The Appendix and Commentary are lettered to correspond to the main specification chapters

27. LRFD Specification for Structural Steel Buildings Pages with Gray edges are not officially part of the Specification p. 16.1-xv Symbol List p. 16.1 xxiii Glossary Written like a legal document Remainder of LRFD book is support information to aid in designing according to the specification

28. Remainder of LRFD Part 1 – Dimensions and Properties Part 2 – General Design Conditions Part 3 – Tension Members Part 4 – Compression Members Part 5 – Flexural Members Part 6 – Combined Loading Part 7 – Bolts …. Part 17 – Misc. Index
