Section 7 -5 -155: REINFORCING AND SEISMIC ANCHORAGE. Section <br /> 3102.4.3 is hereby amended to read as follows: <br /> (a) Every masonry or concrete chimney shall be designed to <br /> resist the horizontal forces specified in this Code. <br /> In addition to the inspections required by Section 108, <br /> the owner shall employ a special inspector who shall <br /> provide inspection during construction. <br /> Section 7 -5 -160: REPAIRS TO BUILDINGS AND STRUCTURES DAMAGED <br /> BY THE OCCURRENCE OF A NATURAL DISASTER. Repair criteria for <br /> structural and nonstructural elements of all buildings and <br /> structures damaged by the occurrence of a declared natural <br /> disaster shall be determined by this section. Required repair <br /> levels shall be based on the damage ratio of the estimated value <br /> of the repairs required to restore the structural members to <br /> their pre -event condition to the estimated replacement value of <br /> the building or structure as follows: <br /> (a) When the damage ratio does not exceed 0.1 (10 percent), <br /> buildings and structures, except essential service <br /> facilities included as Category I buildings and <br /> structures in Table 16 -K, shall at a minimum be <br /> restored to their pre -event condition. <br /> (b) When the damage ratio is greater than 0.1 (10 percent) <br /> but less than 0.5 (50 percent), buildings and <br /> structures, except essential service facilities <br /> included as Category I buildings and structures in <br /> Table 16 -K, shall have the damaged structural members <br /> including all critical ties and connections associated <br /> with the damaged structural members, all structural <br /> members supported by the damaged member and all <br /> structural members supporting the damaged members <br /> repaired and strengthened to bring them into compliance <br /> with the force levels, connection requirements, and <br /> displacement criteria of the Building Code. This <br /> criteria shall apply to essential service facilities <br /> when the damage ratio is less than 0.3 (30 percent). <br /> EXCEPTION: For buildings with rigid <br /> diaphragms where the above required repair <br /> and strengthening increases the rigidity of <br /> the resisting members, the entire lateral <br /> force - resisting system of the building shall <br /> be investigated. When in the opinion of the <br /> building official, an unsafe or adverse <br /> condition has been created as a result of the <br /> increase in rigidity, the condition shall be <br /> corrected. <br /> 6 <br />
