Identify the structural designer's responsibilities: safety, cost, and constructability, and note how safety controls deformations and vibrations, while cost and constructability focus on standard sections and simple connections.
Explore economical design of steel members by prioritizing labor efficiency, open communication among designers, fabricators, and erectors, and using standard sections across locations to reduce labor and assembly costs.
Celebrate completing chapter 1 and prepare for a lengthy subjective assignment drawn from the course book; email the instructor to access answer documents.
Explore the differences between specifications and building codes, examine dead loads, live loads, and environmental loads; discuss design philosophies, and illustrate factor loads per ASC seven with three examples.
Define dead loads as forces that remain constant through a structure’s life, including steel frames, walls, floors, roofs, and fixtures, and estimate them using trial-and-error methods and material tables.
Compute the governing beam load by tributary width and total dead and live loads, including beam self-weight. Apply seven load-factor equations to obtain the maximum factored load per foot.
Calculate the maximum factor load on a column by applying load combinations to axial loads (dead, live, wind, earthquake) and identify a 665 kips design value.
Celebrate completing the first part of the AISC steel design course and maintain momentum as you move into part two to learn the analysis and design of tension members.
Part 1 of 7 of the Steel Design Course will teach you the fundamentals of design.
It will go over structural steel as a material, its behavior, and other properties such as its advantages and disadvantages, different steel sections, stress-strain relationships in steel, the use of modern steel, economical design of steel structures, structural failure, the duties and responsibilities of a structural designer, and navigating the AISC Manual. This section of the course will also cover the several types of loads (dead, live, and environmental), design methodologies (ASD and LRFD), design philosophies (LRFD), and load combinations utilized in steel structure analysis using the ASCE 7 code. We will also look at its practical use through a variety of scenarios. The design methodology used throughout the course will be LRFD. All the lectures in this course will be based on the book "Structural Steel Design, 5th Edition, by Jack C. MacCormac and Stephen F. Csernak". American Institute of Steel Construction (AISC ) 14th Edition will be referred to throughout the course.
Future sections of this course will cover subjects such as tensile member analysis and design, compression member design, flexure member design, different types of connection (bolted, welded) design, and several other topics.
All you need is a decent understanding of structural mechanics and engineering-level mathematics. Students are also expected to have access to the AISC Specification and ASCE 7 code.
