1614.9 Lateral -Force -Resisting Elements Normal to the Downhill Direction.
1614.9.1 General. In the direction norinal to the downhill direction, lateral -force -
resisting elements shall be designed in accordance with the requirements of this
section.
1614.9.2 Base Shear. In developing the base shear for seismic design, the response
modification coefficient (R) shall not exceed 4.5 for bearing wall and building frame
systems.
1614.9.3 Vertical Distribution of Seismic Forces. For seismic forces acting normal
to the downhill direction the distribution of seismic forces over the height of the building
using Section 12.8.3 of ASCE 7 shall be determined using the height measured from
the top of the lowest level of the building foundation.
1614.9.4 Drift Limitations. The story drift below the base level diaphragm shall not
exceed 0.005 times the story height. The total drift from the base level diaphragm to the
top of the foundation shall not exceed 3/4 inch (19 mm). Where the story height or the
height from the base level diaphragm to the top of the foundation varies because of a
stepped footing or story offset, the height shall be measured from the average height of
the top of the foundation. The story drift shall not be reduced by the effect of horizontal
diaphragin stiffness.
Where code -prescribed wind forces govern the design of the lateral force resisting
system norriial to the downhill direction, the drift limitation shall be 0.0025 for the story
drift and the total drift from the base level diaphragrn to the top of the foundation may
exceed 3/4 inch'(1 9 mm) when approved by the Department. In no case, however, shall
the drift limitations for seismic forces be exceeded.

1614.9.5 Distribution of Lateral Forces.
1614.9.5.1 General. The design lateral force shall be distributed to lateral -force -
resisting elements of varying heights in accordance with the stiffness of each
individual element.
1614.9.5.2 Wood Structural Panel Sheathed Walls. The stiffness of a stepped
wood structural panel shear wall may be detennined by dividing the wall into
adjacent rectangular elements, subject to the same top of wall deflection. Deflections
of shear walls may be estimated by Section 2305.3.2. Sheathing and fastening
requirements for the stiffest section shall be used for the entire wall. Each section of
wall shall be anchored for shear and uplift at each step. The minimum horizontal
length of a step shall be eight feet (2438 mm) and the maximum vertical height of a
step shall be two feet, eight inches (813 mm).
1614.9.5.3 Reinforced Concrete or Masonry Shear Walls. Reinforced concrete

designed to resist lateral forces below the base level diaphragm in the direction normal
to the downhill direction:
1. Cement plaster and lath,
2. Gypsum wallboard, and
3. Tension -only braced frames.
Braced frames designed in accordance with the requirements of Chapter 22 of this
Code may be designed as lateral -force -resisting elements in the direction normal to
the downhill direction, provided lateral forces do not induce flexural stresses in any
member of the frame. Deflections of frarnes shall account for the variation in slope of
diagonal members when the frame is not rectangular.
