The structure under this contract has been designed and detailed for
the loads and conditions stipulated in the contract and shown on these
drawings. Any alterations to the structural system or removal of any
component parts, or the addition of other construction materials or loads
must be done under the advice and direction of a registered architect,
civil or structural engineer. ATY Building Services will assume no
responsibility for any loads not indicated. This ATY steel building is
designed with ATY Building Services' standard design practices which are
based on pertinent procedures and recommendations of the following
organizations and codes : -American Institute of Steel Construction
"Specification for the design fabrication and erection of structural steel
for buildings" 9th edition. -American Iron and Steel Institute
"Specification for the design of cold
formed steel structural members"
1986 edition with 1989 addendum. -American Welding Society "Structural
Welding Code" AWS D1.1-87 Chapter 2 relating to prequalified complete
joint penetration groove welds and chapter 8 part B relation to allowable
stresses. -Metal Building Manufacturers Association "Specification for the
design
fabrication and erection of the structural system" most current
edition. Material properties of steel plate and sheet used in fabrication
of primary rigid frames and all primary structural framing members (other
than cold-formed sections) conform to ASTM A-529 or A-570 or A-572 all
with a minimum yield point of 50 KSI. Material properties of cold formed
light gage steel members conform to the requirements of ASTM A-570, with a
minimum yield point of 57 KSI. High strength bolts and their installation
shall conform to ASTM specification A-325 and are designed as bearing type
connections with threads included in the shear plane. Tightening of these
bolts is recommended by the Turn-of-nut method, per "AISC Specification
for Structural Joints." All primary structural members except bolts and
fasteners shall receive one coat of Iron Oxide inhibitive primer. Shop and
field inspections and associated fees are the responsibility of the
contractor, unless stipulated otherwise.
