American Concrete Design
Section 3
3-36
• If the thickness of the web is the same as the width of one
of the flanges but not the other, the member is designed as
a T-section or a rectangular section, depending on which
side the compression due to bending is at.
• If the web thickness does not match the width of either
flange, design is done using the rules applicable for T-
beams – one flange is in compression, the other in tension,
and tensile capacity of concrete on the tensile side of the
neutral axis is ignored.
The program is also able to design the beam as a doubly reinforced
section if it is unable to design it as a single-reinforced section.
3. The parameters for designing these members are as shown in Table
3.1 of this manual. Detailed output on design at individual section
locations along the member length may be obtained by setting the
TRACK parameter to 3.0.
