lateral-force-resisting system shall be evaluated and repaired in accordance with the applicable <br />provisions of Section 3403.6.2.2.1 through 3403.6.2.2.3. <br />3403.6.2.2.1 Evaluation. The building shall be evaluated by a registered design professional, <br />and the evaluation findings shall be submitted to the building official. The evaluation shall <br />establish whether the damaged building, if repaired to its pre-damage state, would comply with <br />the provisions of the building code. Wind forces for this evaluation shall be those prescribed in <br />the building code. Seismic forces for this evaluation are permitted to be the reduced level seismic <br />forces specified in Code Section 3403.6.1.1.3. <br />3403.6.2.2.2 Extent of repair for compliant buildings. If the evaluation establishes compliance <br />of the pre-damage building in accordance with Section 3403.6.2.2.1, then repairs shall be <br />permitted that restore the building to its pre-damage state, using materials and strengths that <br />existed prior to the damage. <br />3403.6.2.2.3 Extent of repair for non-compliant buildings. If the evaluation does not establish <br />compliance of the pre-damage building in accordance with Section 3403.6.2.2.1, then the <br />building shall be rehabilitated to comply with applicable provisions of the building code for load <br />combinations including wind or seismic forces. The wind design level for the repair shall be as <br />required by the building code in effect at the time of original construction unless the damage was <br />caused by wind, in which case the design level shall be as required by the code in effect at the <br />time of original construction or as required by the building code, whichever is greater. Seismic <br />forces for this rehabilitation design shall be those required for the design of the predamaged <br />building, but not less than the reduced level seismic forces specified in Section 3403.6.1.1.3. <br />New structural members and connections required by this rehabilitation design shall comply with <br />the detailing provisions of the building code for new buildings of similar structure, purpose, and <br />location. <br />3403.6.2.3 Substantial structural damage to vertical load-carrying components. Vertical <br />load-carrying components that have sustained substantial structural damage shall be rehabilitated <br />to comply with the applicable provisions for dead and live loads in the building code. <br />Undamaged vertical load-carrying components that receive dead or live loads from rehabilitated <br />components shall also be rehabilitated to carry the design loads of the rehabilitation design. New <br />structural members and connections required by this rehabilitation design shall comply with the <br />detailing provisions of the building code for new buildings of similar structure, purpose, and <br />location. <br />3403.6.2.3.1 Lateral force-resisting elements. Regardless of the level of damage to vertical <br />elements of the lateral force-resisting system, if substantial structural damage to vertical load- <br />carrying components was caused primarily by wind or seismic effects, then the building shall be <br />evaluated in accordance with Section 3403.6.2.2.1 and, ifnon-compliant, rehabilitated in <br />accordance with Section 3403.6.2.2.3. <br />3403.6.2.4 Less than substantial structural damage. For damage less than substantial <br />structural damage, repairs shall be allowed that restore the building to its pre-damage state, using <br />materials and strengths that existed prior to the damage. New structural members and <br />connections used for this repair shall comply with the detailing provisions of the building code <br />for new buildings of similar structure, purpose, and location. <br />ORDINANCE NO. 2007-022 2g <br />
