Description

CIE 428: Steel Design - Fall 2020 COURSE DESCRIPTION: The course emphasizes a theoretical understanding of fundamental concepts in analysis and design of steel structures. Focuses on building structures; topics addressed in the class include materials, probabilistic underpinnings of structural steel design, tension members, compression members, beams and beam-columns, welded and bolted connections, composite construction, and analysis and design of steel structures for gravity, wind, and seismic loads.

Midterm exam has two components. The written component is scheduled on Thursday 10/29 during recitation time and will be conducted remotely. Students are expected to connect to Zoom during the exam and have their phone or laptop camera on for the full duration of exam. The oral component will be completed during a 10-min Zoom meeting with the instructor on 11/02 or 11/03. Meeting time for students will be arranged in September. Final exam is scheduled on 12/16 from 11:45 am to 2:45 pm. The exam will be conducted remotely, and students are expected to connect to Zoom during the exam and have their phone or laptop camera on for the full duration of exam.

Sustained effort starting today: follow the course material on weekly basis, and complete homework assignments during the semester to develop understanding for the fundamental concepts. For the assignments, although students may consult with classmates, it is expected that solutions that are submitted, reflect the individual work of students. A significant part of engineering is written communication of analysis and design proposals. Heavy emphasis will be placed on clarity, organization and readability of your work; (a) all assignments must be submitted with no more than one problem per page; (b) write your name, course and homework number on a cover sheet; (c) a clear and well-labeled drawing or free body diagram as appropriate must be presented with every problem; (d) always use units everywhere in your work – a number without units makes no sense in engineering; (e) Show each step of the problem and clearly explain the logic being used; (f) clearly box all final answers. Late assignments will be penalized 10% for every day that is late, and after one week, no credit will be given. In certain cases, students may be eligible to receive a temporary incomplete (‘I’) grade. A grade of incomplete (‘I’) indicates that additional course work is required to fulfill the requirements of a given course. Students may only be given an ‘I’ grade if they have a passing average in coursework that has been completed and have well-defined parameters to complete the course requirements that could result in a grade better than the default grade. An ‘I’ grade may not be assigned to a student who did not attend the course. Detailed information is available from the Undergraduate Course Catalog, https://catalog.buffalo.edu/policies/explanation.html. The materials provided by the instructor (PPT, videos, etc.) in this course are for the use of the students enrolled in the course only.

COURSE OBJECTIVES: When you graduate as a Civil Engineer, you will be responsible for designing buildings, roads and railroads, bridges, retaining walls, water carrying pipes and many other structures that make up the backbone of our society. To do this, you must be able to design these structures for strength and serviceability. In EAS207 – Statics, you learnt to calculate internal forces in statically determinate structures; in EAS209 – Mechanics of Materials, you learnt about stresses and how to calculate deflections of beams; and in CIE 323 – Structure I, you began the study of deflections of structures and analysis of indeterminate structures. In CIE324, you were

introduced to the concept of design in civil engineering. Students who take this course will be expected to achieve the following objective: i. Internalize the engineering thought process by developing ability to solve real world problems in a rational, systematic, and creative manner; ii. Develop a working knowledge of the theory and practice of structural steel design, iii. Apply the AISC-LRFD steel design procedures; iv. Design primary steel structural elements of a building and their connections. v. Develop an understanding for analysis of steel structures under fire loading. COURSE LEARNING OUTCOMES: When you complete this course, you will be able to: Course learning outcomes 1. Select the proper loads the structure must be able to resist 2. Formulate a structural model of the structure and analyze this model subjected to the various possible critical loading conditions to obtain the governing axial forces, flexural moments, and shears 3. Select structural members that satisfies the strength, stability, and serviceability limit states, at minimum cost (or least weight, as a proxy) 4. Design connections able to transfer these forces

Contribution of CIE428 towards fulfillment of Student Outcomes (SO): (1) Ability to identify, formulate and solve complex engineering problems by applying principles of engineering, science and mathematics: CIE 428 is an engineering design course that requires the student to understand physical behavior of structures for various limit states, and how these principles are captured in equations used to achieve satisfactory design. This is one of the most fundamental aspects of this course. Many problems presented in class and in homework assignments require that the students identify the appropriate ways to solve a problem and approach “real-world” problems in a disciplined and structured fashion, using engineering knowledge and judgment. Students must understand the limits of applicability of each design equation, the underlying concepts/assumptions to correctly apply design requirements, and must sometimes use conservative assumptions in absence of exact knowledge. (2) An ability to apply engineering design to produce solutions that meet specified needs with consideration of public health, safety and welfare, as well as global, cultural, social, environmental and economic factors: Small “real-world” structures and components are used in design examples and assignments. The focus here is on determinate structures, for which components are the building blocks of entire structural systems. Minimum weight goals and geometry-related constraints are primarily considered, along with practical issues commonly encountered in structural steel design. Many problems focus on the use of the AISC Engineering Manual to expedite calculation whenever applicable. Students must be able to recognize when available design aids are applicable, and when they are not applicable, because misuse is a recipe for disaster.

(3) An ability to communicate effectively with a range of audiences: The ability to present all calculations in a systematic and coherent manner, with proper reference to specific design specifications, is most important. Well-organized solutions must reflect the clarity of the thought process, with all appropriate FB diagrams, sketches, and presentation of intermediate steps.

ACADEMIC INTEGRITY Academic integrity is a fundamental university value. Through the honest completion of academic work, students sustain the integrity of the university while facilitating the university's imperative for the transmission of knowledge and culture based upon the generation of new and innovative ideas.
