Note to Tables: Shaded table cells indicate that the spacing is not feasible with respect to the proposed backfill height.

Footnote 1

Table 4.2.1.1(a) and (b) are based on the following assumptions:

The design is applicable for the seismic zones indicated in the tables.
The design is applicable to structures that are constructed on soil Types A, B, C and D.
Maximum building dimension is 24.0 m.
Maximum building width is 12.0 m.
Maximum floor clear span is 6.0 m.
Maximum roof clear span is 12.0 m with a maximum overhang of 2 m.
Maximum number of stories above grade is two (2).
Maximum number of stories below grade is one (1).
Maximum height of foundation walls and first floor walls is 3.66 m.
Maximum height of above grade second floor wall is 3.05 m.
The concrete walls are evenly distributed on each side and in each direction.
K₀ = 0.50; density of soil = 18kN/m³.
Roof dead load is 0.70 kPa.
Floor dead load is 0.70 kPa.
Snow load is 4.0 kPa.
Floor live load is 1.90 kPa.
Factored surcharge lateral pressure = 2.4 kPa.
Loads include earth pressure and surcharge loads, plus gravity load. Gravity load assumes 2 ICF storeys and wood roof frame.
All walls shall be proportionally and evenly distributed in both the transverse and longitudinal direction of the building.
Below grade walls are considered to be supported by the floor system at the top.
Slenderness of the wall shall not exceed 25.
A minimum of 2 lengths of solid concrete in all below-grade and above-grade shear walls without openings is required in each exterior wall in each building direction on all levels of the building. (For more information, please refer to the shear wall limits as indicated in the TACOMA Engineers, Report No. 2284.)
Reinforcing bars shall be hard grade deformed bars conforming to CSA G30.12-M, "Billet-Steel Bars for Concrete Reinforcement," Grade 400. Specified yield strength of reinforcement, fy, is 400 MPa.
Wall design detailing bends, placement, spacing, splicing and protection of reinforcement shall be in accordance with CAN/CSA-A23.3-04(R2000), "Design of Concrete Structures."
For below grade walls, the placement of vertical reinforcement shall be located on the inside face of the wall, between horizontal bars. For 150-mm-thick walls, the concrete cover to the vertical reinforcement (measured from the edge of concrete to centre of reinforcement bars) shall be 55 mm. For 200-mm- and 250-mm-thick walls, the concrete cover shall be 80 mm and 84 mm.
Horizontal reinforcing shall be as per the tables, plus 1-10M continuous bar shall be placed 150 mm from the top of the wall and at floor level.
Two full height vertical bars equal to the vertical reinforcing within the wall system are to be installed at all corners and on each side of the wall openings.
Two 15M bars shall be placed around all openings and shall extend 600 mm (24") beyond each side of the openings.
Minimum 28 day concrete compressive strength of 20 MPa. Maximum aggregate size is 13 mm for the 150-mm-thick concrete walls and 19 mm for 200-mm and 250-mm concrete walls.
Concrete pours shall only be terminated at locations of lateral support.
Concrete shall be allowed to cure for a minimum of seven days prior to backfilling.
All materials and workmanship shall conform to the requirements of the NBC 2005 and its Revisions and Errata that have been released as of the issue date of these tables.

Note to Tables: Shaded table cells indicate that the spacing is not feasible with respect to the proposed wall height.

Footnote 1

Table 4.2.2.1(a) to (i) are based on the following assumptions:

The design is applicable for the seismic zones and the maximum factored wind pressure indicated in the tables.
Loads include all applicable gravity loads, seismic and wind loads.
The exterior walls have been designed to include the option of cladding with clay bricks.
For allowable building dimensions, see Note (1) to Tables 4.2.1.1(a) and (b).
For assumed loads, see Note (1) to Tables 4.2.1.1(a) and (b).
Vertical reinforcement is to be placed in the centre of the wall.
For concrete and steel material properties, see Note (1) to Tables 4.2.1.1(a) and (b).
Horizontal reinforcing shall be as per the tables, plus 1-10M continuous bar shall be placed 150-mm from the top of wall and at floor level.
Two full height vertical bars equal to the vertical reinforcing within the wall system are to be installed at all corners and on each side of the wall openings.
Two 15M bars shall be placed around all openings and extend 600-mm (24") beyond each side of the openings.
All materials and workmanship shall conform to the requirements of the NBC 2005 and its Revisions and Errata that have been released as of the issue date of these tables.

Note: Shaded table cells indicate that the spacing is not feasible with respect to the proposed core thickness.

Footnote 1

Tables are based on the following assumptions:

The design of the lintels falling under the scope of the referenced tables is limited to factored, uniformly distributed gravity loads and does not include lateral loads, or point loads such as concentrated loads created by girder, trusses, columns, and beams.
The minimum height of the lintel is 200 mm.
The top of all lintels shall be laterally supported by the building roof and floor system.
Stirrups are single leg fabricated from #10 bars spaced at 76 mm on centre for 200-mm-deep lintels, 127 mm for 300-mm-deep lintels, 203 mm for 400-mm-deep lintels, 304 mm for 600-mm-deep lintels and 350 mm for 750- mm- deep lintels.
Lintel reinforcing is located 89 mm from the bottom of lintel and projects 600 mm into lintel support on each side of the opening.
Specified compressive strength of concrete, @ 28 days f'_c, is 20 MPa.
Specified yield strength of reinforcement, f_y, is 400 MPa.
Two #15 bars should be placed around all openings and shall extend at least 600 mm beyond each corner of the opening.
