4.1.1.

(1) The scope of this Part shall be as described in Subsection 1.1.2. of Division A.

(1) Buildings and their structural members and connections including formwork and falsework shall be designed to have sufficient structural capacity and structural integrity to safely and effectively all loads, effects of loads and influences that may reasonably be expected, having regard to the expected service life of buildings, and shall in any case satisfy the requirements of this Section.

(2) Buildings and their structural members shall be designed for serviceability, in accordance with Articles 4.1.3.4. to 4.1.3.6.

(3) All permanent and temporary structural members, including formwork and falsework of a building, shall be protected against loads exceeding the specified loads during the construction period except when, as verified by analysis or test, temporary overloading of a structural member would result in no impairment of that member or any other member.

(4) Precautions shall be taken during all stages of construction to ensure that the building is not damaged or distorted due to loads applied during construction.

(1) Except as provided in Sentence (2) and (3), buildings and their structural members shall be designed in conformance with the procedures and practices provided in this Part.

(2) Provided the design is carried out by a person especially qualified in the specific methods applied and provided the design demonstrates a level of safety and performance in accordance with the requirements of this Part, buildings and their structural components falling within the scope of this Part that are not amenable to analysis using a generally established theory may be designed by,

(a) evaluation of a full-scale structure or a prototype by a loading test, or

(b) studies of model analogues.

(3) Communications towers, dish antennas and their supporting structures shall conform to CSA S37, “Antennas, Towers, and Antenna Supporting Structures”.
