6.Load Bearing structures not specifically provided for in these bylaws
1. COMBINATION OF LOADS AND FORCES.
(1) Every building or portion of a building shall be designed and constructed to sustain the most adverse combination of dead loads, superimposed loads and forces to which it may reasonably be expected to be subjected, which loads and forces shall be taken to be not less than minimum set out in C.A.S. 160, Loads and forces.
(2) The design of every building or portion of a building shall make provision for the combination of loads and forces producing the most adverse conditions of induced stress, deflection and structural instability.
2.RESISTANCE TO OVERTURNING.
The moment resisting overturning of any building or part of a building, including the moment provided by foundations, anchorages or other fixings shall exceed the overturning moment due to the most adverse combinations of dead and superimposed loads and forces by at least 50 per centum.
3. CONCRETE.
The design and construction of reinforced, prestressed or precast concrete structural work shall be deemed to satisfy the requirements of these by-laws if the design and construction is in accordance with-
a) C.A.S. 164 The structural use of reinforced concrete in buildings; or
b) C.A.S. 165 The structural use of prestressed concrete in buildings; or
c) C.A.S. 166 The use of use of precast concrete; or
d) C.A.S. 170 The structural use of concrete
4.STEEL
The design and construction of structural steel work shall be deemed to satisfy the requirements of these by-laws if the design and construction is in accordance with C.A.S. 157, The use of structural steel in building.
5.TIMBER
The design and construction of structural timber shall be deemed to satisfy the requirements of these by-laws if the design and construction is in accordance with C.A.S 162, The use of structural timber in building.
6. LOAD BEARING STRUCTURES NOT SPECIFICALLY PROVIDED FOR IN THESE BYLAWS
(1) All load-bearing structures not specifically provided for in these by-laws shall be designed by a structural engineer, who shall provide a certificate to the local authority in accordance with the provisions of paragraph (e) of subsection(1) of section 6 of Chapter 2.
(2) No person shall carry out any work in respect of which an undertaking of supervision has been given in a certificate referred to in subsection (1) without the carrying out of such work being supervised in accordance with such an undertaking.
