2. The providing mill shall certify in writing to the consumer or builder on a form to be provided by the State Building Code Standards Committee that the quality and safe working stresses of such lumber are equal to or exceed No. 2 grade in accordance with grading practices established by an approved lumber grading or approved testing agency.

Exception: Load bearing walls shall be of stud grade minimum.

This certification shall be filed with the local building official having jurisdiction as part of the building permit application;

2310.4 Sizing Criteria for Native Softwood Lumber

1. Sizing criteria: For lumber sized in accordance with the AF&PA NDS-01, conventional span tables in this code shall be permitted to be used for establishing span and spacing characteristics for all structural members.

2. Stress increases: Lumber which is sized in excess of the dimensions established by the AF&PA NDS-01 for the given nominal size referenced shall be allowed to have increased loads providing structural calculations are submitted verifying such increases. See Table 2310.

2310.5 Moisture Content

The moisture content for structural framing shall be 19% or less unless the producer indicates that the lumber is surfaced green.

2310.6 Post and Beam Type Structures

Native hardwood and softwood lumber are permitted in post and beam timber-type structures. Design drawings and calculation shall be by a Rhode Island registered architect or engineer and submitted to the building official for approval.

2310.7 Responsibilities

Any existing gravity load-carrying structural element for which an alteration causes an increase in design gravity load of more than 5 percent shall be strengthened, supplemented, replaced or otherwise altered as needed to carry the increased gravity load required by this code for new structures. Any existing gravity load-carrying structural element whose gravity load-carrying capacity is decreased as part of the alteration shall be shown to have the capacity to resist the applicable design gravity loads required by this code for new structures.

3404.3.1 Design live load.

Where the alteration does not result in increased design live load, existing gravity load carrying structural elements shall be permitted to be evaluated and designed for live loads approved prior to the alteration. If the approved live load is less than that required by Section 1607, the area designed for the nonconforming live load shall be posted with placards of approved design indicating the approved live load. Where the alteration does result in increased design live load, the live load required by Section 1607 shall be used.

3404.4 Existing structural elements carrying lateral load.

Except as permitted by Section 3404.5, where the alteration increases design lateral loads in accordance with Section 1609 or 1613, or where the alteration results in a structural irregularity as defined in ASCE 7, or where the alteration decreases the capacity of any existing lateral load-carrying structural element, the structure of the altered building or structure shall be shown to meet the requirements of Sections 1609 and 1613.

Exception:

Any existing lateral load-carrying structural element whose demand-capacity ratio with the alteration considered is no more than 10 percent greater than its demand-capacity ratio with the alteration ignored shall be permitted to remain unaltered. For purposes of calculating demand-capacity ratios, the demand shall consider applicable load combinations with design lateral loads or forces per Sections 1609 and 1613.

3405.2.2 Extent of repair for compliant buildings.

If the evaluation establishes compliance of the pre-damage building in accordance with Section 3405.2.1, then repairs shall be permitted that restore the building to its pre-damage state, based on material properties and design strengths applicable at the time of original construction.

3405.2.3 Extent of repair for noncompliant buildings.

If the evaluation does not establish compliance of the pre-damaged building in accordance with Section 3404.2.1, then the building shall be rehabilitated to comply with applicable provisions of this code for load combinations that include wind or seismic loads. The wind loads for the repair shall be as required by the building code in effect at the time of original construction, unless the damage was caused by wind, in which case the wind loads shall be as required by this code.

The value for building height shall be the lesser value determined by the formula in Section 3412.6.1.1. Chapter 5 shall be used to determine the allowable height of the building, including allowable increases due to automatic sprinklers as provided for in Chapter 5. Subtract the actual building height in feet from the allowable and divide by 12 1/2 feet. Enter the height value and its sign (positive or negative) in Table 3412.7 under Safety Parameter 3412.6.1, Building Height, for fire safety, means of egress and general safety. The maximum score for a building shall be 10.

Where:

AH = Allowable height in feet from Table 504.

EBH = Existing building height in feet.

AS = Allowable height in stories from Table 504.

EBS = Existing building height in stories.

CF = 1 if (AH) – (EBH) is positive.

CF = Construction-type factor shown in Table 3412.6.6(2) if (AH) – (EBH) is negative.

Note:

Where mixed occupancies are separated and individually evaluated as indicated in Section 3412.6, the values AH, AS, EBH and EBS shall be based on the height of the occupancy being evaluated.

3412.6.2 Building area.

The value for building area shall be determined by the formula in Section 3412.6.2.2. Section 506 and the formula in Section 3412.6.2.1 shall be used to determine the allowable area of the building. This shall include any allowable increases due to frontage and automatic sprinklers as provided for in Section 506. Subtract the actual building area in square feet from the allowable area and divide by 1,200 square feet. Enter the area value and its sign (positive or negative) in Table 3412.7 under Safety Parameter 3412.6.2, Building Area, for fire safety, means of egress and general safety. In determining the area value, the maximum permitted positive value for area is 50 percent of the fire safety score as listed in Table 3412.8, Mandatory Safety Scores.

3412.6.2.1 Allowable area formula.

The following formula shall be used in computing allowable area:

Aa = [At + (At If) + (At Is)] (Equation 34-3)

Where:

Aa = Allowable building area per story (square feet).

At = Tabular building area per story in accordance with Table 503 (square feet).

Is = Area increase factor due to sprinkler protection as calculated in accordance with Section 506.3.

If = Area increase factor due to for frontage as calculated in accordance with Section 506.2.

3412.6.2.2 Area formula.

The following formula shall be used in computing the area value. Determine the area value for each occupancy floor area on a floor-by-floor basis. For each occupancy, choose the minimum area value of the set of values obtained for the particular occupancy

Where:

i = Value for an individual separated occupancy on a floor.

n = Number of separated occupancies on a floor.
