    A4111 Structures I

    Technology Requirement
    Peter J. Galdi

    INTRODUCTION
    The course will address the following issues: definitions of structural design; structural and architectural design; identification of structural systems; separation of structural and non-structural components; graphics and statics of structural systems; structural materials and their properties; axially and Transversely loaded structural members; method of selection of structural materials; and preliminary design methods. The course will also study the qualitative and quantitative aspects of the design and analytical processes, with appropriate examples taken predominantly from architecture and engineering of the last two hundred years. We will study this work through the use of slides and /or working drawings where applicable. Homework assignments and quizzes will focus on the structural design methods and issues in simplified but realistic form.

    LECTURE SCHEDULE AND TOPICS
    1. Structural requirements of design Loads and forces, design approaches: strength and flexibility
    2. Graphics and statics of structures Attributes of forces and moments (magnitude, direction, laws of vector addition) Force systems (gravity, wind, thermal) Force types (concentrated, uniform) Free body diagrams Support types (free, fixed, hinged)
    3. Laws and principles of structural statics Static versus dynamic equilibrium Laws of translational and rotational equilibrium Newton's laws Principles of Cuts
    4. Equilibrium of structural systems Sign conventions, reactions, examples: analytical and graphical Indeterminance and instability
    5. Structures and their systems Structural and non-structural members Typical limiting proportions and spans of structural components
    6. Properties of modern structural materials; Quiz #1 Axial stress and strain, Hooke's law Stress/strain curves for axially loaded common materials Elastic design theory Thermal loads and stresses
    7. Design of structural components Columns, walls, beams, plates, shells, hangers
    8. Axially loaded structural elements Tension members: design criteria Steel plates, beam shapes, cables Connections: Codal requirements
