New
ADAPT-Builder
v20
has
been
updated
to
ensure
that
users
can
take
advantage
of
designs
conforming
to
the
latest
building
code
standards.
The
2020
version
includes
applicable
code
provisions
from
ACI318-19:
Building
Code
Requirements
for
Structural
Concrete.
Provisions
found
in
the
latest
design
standard
that
have
been
included
in
ADAPT-Builder
include:
Reinforcement
strain
limit
has
been
revised
for
all
criteria
and
system
types
(beam,
one-way
and
two-way
slabs
for
RC
and
PT
mode).
(ACI
318-19,
7.3.3.1)
Minimum
flexural
reinforcement
for
non-prestressed,
reinforced
one-
and
two-way
slabs
shall
meet
a
minimum
area
of
flexural
reinforcement
of
0.0018Ag.
(ACI
318-19,
7.6.1.1)
For
two-way
non-prestressed,
reinforced
concrete
slabs
the
equation
for
modulus
of
rupture
is
modified
for
fy
exceeding
80,000
psi.
This
change
applies
to
cracked
deflection
calculations
in
the
program
where
fr
is
used
to
calculate
cracking
moments,

(ACI
318-19,
8.3.1.1)
Minimum
extensions
for
deformed
reinforcement.
Bar
curtailment
in
Buildersum
was
adjusted
for
compliance.

The
reinforcement
strain
limit
for
beams.
(ACI
318-19,
9.3.3.1)
For
the
calculation
of
the
minimum
flexural
reinforcement
amount
for
beams
with
fy
exceeding
80,000
psi,
the
value
of
fy
shall
be
limited
to
a
maximum
of
80,000
psi.
