Instructional Objectives: At the end of this lesson, the student
should be able to: identify the primary load carrying mechanisms of
reinforced concrete beams
and slabs, name three different types of reinforced concrete
beam with their specific
applications, identify the parameters influencing the effective
widths of T and L-beams, differentiate between one-way and two-way
slabs, state and explain the significance of six assumptions of the
design, draw the stress-strain diagrams across the depth of a
cross-section of
rectangular beam, write the three equations of equilibrium,
write and derive the expressions of total compression and tension
forces C
