Print this page Design of Reinforced Concrete Beams per ACI 318-02
Jose-Miguel Albaine, M.S., P.E.
Course Outline
The most important single characteristic of a beam is its strength. The two most important quantities that must be considered in the design of beams are vertical shear and bending moment. In the design of reinforced concrete beams for the limit state of failure several factors need to be reconciled since these beams are neither homogeneous nor elastic at the ultimate load.
This course will cover the basic concepts of design of reinforced concrete beams, based on the new criteria specified in the latest edition of the American Concrete Institute (ACI), Building Code Requirements for Structural Concrete ACI 318-02, (herein referred as ACI 318).
The topics included
are: design assumptions, general principles and requirements, minimum reinforcement
for flexural members, new load factors and strength reduction factors, and distribution
of flexural reinforcement. Doubly reinforced sections, nonrectangular sections,
T-beams two-way slab, deep beams, shear and torsion, and prestressed beams are
not in the scope of this course.
This course includes
a multiple-choice quiz at the end,
Learning Objective
This course is a practical guide for professional engineers, architects, and designers who want to learn the latest specification regarding the design of reinforced concrete beams and slabs. After completion of course you should be able to:
- Identify the design methods and codes.
- Review the design assumptions
- Determine the stress and strain distribution across the beam depth
- Identify the "balanced conditions" on the cross section
- Learn the new strain limit formulation for the design and analysis of beams (tension-controlled elements)
- Calculate the
flexural design strength of reinforced concrete beams

Course Summary
This course has covered the basic principles related to the design of nonprestressed singly reinforced concrete rectangular beams using the latest edition of the Building Code Requirements for Structural Concrete ACI 318-02.
The items discussed
in this lecture included the analysis and design of singly reinforced rectangular
sections, design assumptions, general requirements, variation of strength reduction
factor, reinforcement strain limits, minimum reinforcement, and new load factors.
Other issues covered were distribution of flexural reinforcement, and distance
between lateral supports.
