  • Structural behavior of loads resisting members in buildings. Properties of structural materials. Primarily for Building Construction majors.


  • To study forces, materials and their strengths (construction focused), topics shall include analysis of structural systems: beams, columns, frames, trusses. Students will also learn axial stress, strain, properties of materials, beam analysis, shear and moment diagrams, bending and shearing stress, deflection and design of typical building beams.
  • COURSE LEARNING OUTCOMES Upon completion of the course students will demonstrate their ability to:
    1. Understand various types of measurement systems for force, area, length etc., and scalar and vector quantities for construction materials. ACCE SLO 19
    2. Understand various force systems, e.g., concurrent, non-concurrent and parallel force systems and equilibrium to explain forces in structures and behavior of construction materials. ACCE SLO 19
    3. Apply the concepts of structural mechanics to understand beam reactions, bending, shear, deflection, compression and tension, as applicable, in beams, columns, trusses, walls and footings. ACCE SLO 19
    4. Quantify and analyze the internal and external forces acting within and upon a structural component under various anticipated loading conditions. ACCE SLO 19
    5. Understand effects of moments of inertia, sectional modulus, radius of gyration and modulus of elasticity on axial stress, strain, shear, moment, bending and shearing stresses, and deflection of various structural systems. ACCE SLO 19
    6. Understand basic principles of equilibrium and structural behavior of beams, frames, footings, trusses and columns. ACCE SLO 19
    7. Understand basic material properties of concrete, steel and timber for design and selection of beams, frames, trusses and columns. ACCE SLO 8.

  • Exams The midterm exam is open-book and open notes exam. Final exam is closed book but students are allowed to bring 1 sheet (standard letter size) with any information. The sheet can be printed on both sides.
  • Homework
    • Assigned homework should be uploaded to the Canvas website by 5PM every Wednesday as one pdf file.
    • In case the server is not working an e-mail with attachment (in pdf file format) can be sent to TA via email.
    • If you submit HW by e-mail, the subject line should be ‘BCN 2405C, HW No., and Your Name Homework solutions will be uploaded to canvas. Students are required to check their HW and make any corrections themselves. Problems should be worked on the engineering paper with 0.5-mm pencil before scanning the HW as a pdf file. Please use not more than 300 dpi resolution to make small files. All sketches should be neatly drawn using a ruler. All answers should be underlined.
      Late work will be penalized.
      • 10% for each class period late
      • Once an assignment has been graded and returned to the class, no more late assignments will be accepted.
  • Quizzes All quizzes are open books, open notes and have equal weight. Two lowest quiz grades will be dropped while calculating final grade because of low performance or absences due to medical reasons, school-related activities, family issues, emergencies, work-related issues and other unforeseen circumstances. No make-up quiz will be given. To complete the course syllabus in time, quiz solutions will be posted on the Internet. All matters about change of quiz grade should be settled within a week after it is given. Depending on raw scores instructor may choose to curve any or all quizzes.
  • Requirements for class attendance and make-up exams, assignments, and other work in this course are consistent with university policies that can be found at:
