Scope:
1.1 General
This Standard provides criteria in accordance with the National Building Code of Canada, for the structural design and evaluation of structures or structural elements made from wood or wood products, including:
a) graded lumber;
b) glued-laminated timber;
c) cross-laminated timber (CLT);
d) mechanically laminated timber (MLT);
e) unsanded plywood;
f) oriented strand board (OSB);
g) composite building components;
h) shearwalls and diaphragms;
i) timber-concrete-composite (TCC);
j) timber piling;
k) pole-type construction;
l) prefabricated wood I-joists;
m) structural composite lumber;
n) permanent wood foundations;
o) plank decking;
p) nail-laminated decking; and
q) structural connections.
1.2 Exclusions
This Standard does not include design of timber bridges.
1.3 Design method
This Standard employs the limit states design method.
1.4 Terminology
In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; “may” is used to express an option or that which is permissible within the limits of the Standard.
Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a Clause is to separate from the text explanatory or informative material.
Notes to tables and figures are considered part of the table or figure and may be written as requirements.
Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
1.5 Units of measurement
If a value for measurement as given in this Standard is followed by an equivalent value in other units, the first stated value is to be regarded as the specification.
1.1
This Standard specifies material and fabrication requirements for corrugated steel pipe, spiral rib pipe, structural plate, and two-flange tunnel liner plate.
1.2
This Standard applies to corrugated steel pipe and buried structures for applications such as culverts, storm sewers, storm water management systems, subdrains, hydraulic structures, grade separations, and tunnels.
1.3
This Standard does not include requirements for hydraulic design, service life, structural design, construction, or installation. For the structural design of products less than 3.0 m in span, refer to ASTM A796/A796M. The structural design of corrugated steel pipe and buried structures greater than or equal to 3.0 m in span is included in CSA S6.
1.4
In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the Standard.
Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.
Notes to tables and figures are considered part of the table or figure and may be written as requirements.
Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
CSA B128.1
1 Scope
1.1 General
This Standard specifies requirements for the design and installation of non-potable water systems.
1.2 Exclusions
This Standard does not cover
(a) the quality of the non-potable water;
(b) maintenance and field testing of non-potable water systems after the initial installation; or
(c) non-potable water systems for industrial or manufacturing processes. Maintenance and field-testing requirements are covered in CSA B128.2.
1.3 Other exclusions
This Standard does not cover and does not preclude further treatment of non-potable water to potable standards.
1.4 Terminology
In CSA Standards, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; “may” is used to express an option or that which is permissible within the limits of the standard; and “can” is used to express possibility or capability. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
