• <br />� <br />N/A STIRRUP SPACING: All beams shall have stirrups spaced at or less than d/2 for Life Safety and <br />Immediate Occupancy throughout their length. At potential plastic hinge locations stirrups shall be <br />spaced at or less than the minimum of 8dn or d/4 for Life Safety and Immediate Occupancy. (Tier 2: <br />Sec. 4.4. I .4.12) <br />N/A JOINT REINFORCING: Beam-column joints shall have ties spaced at or less than 8dn for Life Safety <br />and Immediate Occupancy. (Tier 2: Sec. 4.4.1.4.13) <br />N/A JOINT ECCENTRICITY: There shall be no eccentricitics larger than 20 percent of the smallest <br />column plan dimension between girder and column centerlines. This statement shall apply to the <br />Immediate Occupancy Performance Level only. (Tier 2: Sec. 4.4.1.4.14) <br />N/A STIRRUP AND TIE HOOKS: The beam stirrups and column ties shall be anchored into thc member <br />cores with hooks of 135° or more. This statement shall apply to the Immediate Occupancy Performance <br />Level only. (Tier 2: Sec. 4.4.1.4.15) <br />NC DEFLECTION COMPATIBILITY: Secondary components shall have the shear capacity to develop the <br />flexura] strength of the elements for Life Safety and shall meet the requirements of Sections 4.4.1.49, <br />4.41.4.10, 4.4.1.4.11, 4.4.1.4.12 and 4.41.4.15 for Immediate Occupancy. (Tier 2: Sec. 4.4.1.6.2) <br />Happens at masonry walls. <br />N/A FLAT SLABS: Flat slabs/plates classified as secondary components shall have continuous bottom steel <br />t6rough the column joints for Life Safety or Immediate Occupancy. (Tier 2: Sec. 4.4. L6.3) <br />Diaphragms <br />C DIAPHRAGM CONTINLTITY: The diaphragms shall not be composed of split-levcl floors. In wood <br />buildings, the diaphragms shall not have expansion joints. (Tier 2: Sec. 4.5.1.1) <br />N/A PLAN IRREGULARITIES: There shall be tensile capacity to develop the strength of the diaphragm at <br />re-entrant corners or other locations of plan irregulari[ies. This statement shall apply to thc Immediate <br />Occupancy Performance L,evel only. (Tier 2: Sec. 4.5.1.7) <br />N/A DIAPHRAGM REINFORCEMENT AT OPENINGS: There shall be reinforcing around all diaphragms <br />openings larger than 50 percent of the building width in either major plan dimension. This statement <br />shall apply to the Immediate Occupancy Performance I.evel only. (Tier 2: Sec. 4.5.1.8) <br />Connections <br />N/A UPLIFT AT PILE CAPS: Pile caps shall have top reinforcement and piles shall be anchored <br />to the pile caps for Life Safety, and the pile cap reinforcement and pile anchorage sha(1 be able to <br />develop the tensile capacity of the piles for Immediate Occupancy.
