Course Objectives

The objectives of the course are to:

  • Provide students with an understanding of the behavior of reinforced concrete structures
  • Develop characteristics of a variety of reinforced concrete structural component types
  • Introduce analytical tools for mathematical modeling of structural elements and systems
  • Apply basic concepts of structural design including deign strength envelopes
  • Provide a solid foundation for subsequent study of more advanced topics
  • Review and reinforce fundamental skills in mathematics, science and engineering statics, strength of materials, structural mechanics, materials testing lab and soil mechanics
  • Provide a understanding of concrete as a construction material
  • Provide laboratory experience with cement, concrete aggregates, and concrete properties
  • Provide students with a team based capstone design experience for the structures portion of the CE curriculum
  • Prepare students for successful completion of the professional FE examination
Topics Covered
  • History, materials, specified strength, and load factors for reinforced concrete.
  • Flexural strength and design reinforcement concrete beams and T-beams.
  • Shear and torsional strength of reinforced concrete.  Beams, and shear [diagonal tension] reinforcement.  Shear wall and deep beams.
  • Flexural and anchorage bond strength and development of reinforcement.  Moment capacity diagrams.
  • Deflection and serviceability requirements for reinforced concrete structures
  • Design of short members under combined flexural and axial loads.
  • Columns under biaxial flexural loads.
  • Design of long members under combined flexural and axial loads by the moment magnifier method.


Computer Usage

First laboratory- Structural Analysis for Concrete Design requires students to model a continuous span on a structural program they've been introduced to in CE 153 (Structural Mechanics).  The exercise requires application of influence lines on an indeterminate beam for maximizing reinforced concrete design parameters (positive and negative bending moments, shear, and inflection points).  Laboratory Design Project requires students to model a basic structural system for given gravity loading.  The computations include use of influence lines for maximizing design parameters.  The structure is then designed, constructed and tested as a part of the comprehensive design project.

Outcomes

Students completing the course will be able to:

  • Perform stress analysis of basic reinforced concrete structural components with a variety of compositions under a multitude of loading conditions
  • Analyze basic structural systems under a multitude of loading conditions, both statically determinate and indeterminate
  • Apply principles of linear-elastic and elasto-plastic behavior and recognize the significance of ductile versus brittle behavior to structural components and systems
  • Understand the properties of and lab test relating to reinforcing steel and concrete and its components
  • Develop a lab experiment to test a physical system
  • Undertake the design of reinforced concrete structural components by simultaneously incorporating multiple design constraints and specifications
