Learning Objective

At the conclusion of this course, the student will:

  • Learn three (3) components of durability;
  • Learn characteristics of fire resistance;
  • Study standard E119 time-temperature curve;
  • Learn temperature variation of reinforcement for different distances to edges, and different concrete weights;
  • Study the four (4) types of column-foundation connections, with regard to eleven (11) points of consideration in design;
  • Calculate development length of straight bars;
  • Find development length of hooked bars;
  • Calculate development length of headed bars;
  • Find increase in beam deflection due to creep and shrinkage;
  • Find force exerted by fully restrained concrete beam as a function of temperature;
  • Learn grout detailing considerations;
  • Study the shear-friction concept and applicable areas;
  • Calculate shear-friction reinforcement;
  • Learn the nine (9) points to be considered in designing epoxy anchors;
  • Calculate epoxy anchor adjustment factors;
  • Find recommended maximum shear due to bolt loading of anchor;
  • Determine the circumstances when corbel design is required;
  • Calculate Nu, d, and Vu for corbels;
  • Design corbel reinforcement;
  • Determine the applicability of connection angles; and
  • Calculate thickness of connection angles, and bolt loading.

Intended Audience
