3-28
d. Extreme compression fiber to centroid of tension
reinforcement distance, d, is taken as 0.8 horizontal length
of the wall (11.10.4 of ACI 318).
e. Flexural design of the wall is carried out in accordance
with provisions of Chapter 10.
f. The flexural (concentrated) reinforcing is located at both
ends (edges) of the length of the wall. Rebar layout
conforms to the spacing requirements of Section 7.6.
Design for compression and out-of-plane bending (Section 14.8)
a. The design is based on the Alternative Design of Slender
Walls procedure.
b. The procedure requires that the wall panel be designed as
simply supported (at top and bottom), axially loaded with
out-of-plane uniform lateral load, with maximum moments
and deflections occurring at mid-height.
c. Minimum distributed reinforcing ratio is controlled by the
in-plane shear design calculations.
d. The reinforcing amount required by 14.8 is over and above
any reinforcing required due to in-plane shear.
3.8.3 Slabs and RC Designer
Purpose
STAAD.Pro includes a full-featured two-way slab design in
accordance with ACI 318-02. The program generates required
orthogonal slab reinforcing based on finite element analysis. This
module is part of the Interactive Design suite of programs
seamlessly incorporated into the STAAD.Pro interface. These
programs become available as top menu choices once the analysis
of a model is successfully completed.
