High Strength Bolts – A Primer for
Structural Engineers
A must-have design guide on struc-
tural bolting, this primer assists engi-
neers in understanding the basis of the
requirements in the RCSC Specification for
Structural Joints Using ASTM A325 or
A490 Bolts. The guide also includes a
chapter dedicated to the static strength of
rivets, which can be invaluable for retro-
fit work. The guide addresses bolt instal-
lation, inspection, behavior, and design.
In addition, specialized topics are cov-
ered, including the proper use of wash-
ers, galvanized bolts, reuse of high-
strength bolts, joints with combined bolts
and weld, and surface coatings.

Steel-Framed Open-Deck Parking
Structures
Design Guide 18 addresses the design
of steel parking structures using five
unique types of deck systems: cast-in-
place reinforced concrete, cast-in-place
post-tensioned slabs, precast double tees,
filigree systems, and hollow-core plank.
Deck system design parameters and
framing systems are discussed in detail,
including design examples in LRFD and
ASD. In addition, there are several chap-
ters that examine mixed-use structures,
fire protection requirements, barriers and
facades, stairs and elevators, and corro-
sion protection for exposed steel in open-
deck parking structures.
