Post-disaster buildings are buildings that are essential to the provision of services in the event of a disaster, and include: hospitals, emergency treatment facilities and blood banks telephone exchanges power generating stations and electrical substations control centres for air, land and marine transportation public water treatment and storage facilities, and pumping stations sewage treatment facilities buildings having critical national defence functions buildings of the following types, unless exempted from this designation by the Chief Building Official authority having jurisdiction : 2 emergency response facilities fire, rescue and police stations, and housing for vehicles, aircraft or boats used for such purposes communications facilities, including radio and television stations.

Load Combination 1. Equipment areas and service rooms including. Exits and fire escapes. Sidewalks and driveways over areaways and basements. Soil Undrained Shear Strength, s u.

Rock 2. Very dense soil and soft rock. Stiff soil. Soft soil. A roof that is lighter than the floor below need not be considered. Except for braced frames and moment-resisting frames, an in-plane discontinuity shall be considered to exist where there is an offset of a lateral-force-resisting element of the SFRS or a reduction in lateral stiffness of the resisting element in the storey below.

Discontinuities in a lateral force path, such as out-of-plane offsets of the vertical elements of the SFRS. Discontinuity in Capacity - Weak Storey. A weak storey is one in which the storey shear strength is less than that in the storey above. The storey shear strength is the total strength of all seismic-resisting elements of the SFRS sharing the storey shear for the direction under consideration. Torsional Sensitivity to be considered when diaphragms are not flexible.

Torsional sensitivity shall be considered to exist when the ratio B calculated according to Sentence 4. A non-orthogonal system irregularity shall be considered to exist when the SFRS is not oriented along a set of orthogonal axes. Vertical Stiffness Irregularity. Weight mass Irregularity. Vertical Geometric Irregularity. Ductile buckling-restrained braced frames. Limited ductility plate walls. Conventional construction of moment -resisting frames, braced frames or plate walls.

Shear walls. Diagonal strap concentrically braced walls. Other cold-formed SFRS s not defined above. Conventional construction of moment-resisting frames, braced frames or plate walls. Part or Portion of Building. All exterior and interior walls except those in Category 2 or 3 1. Cantilever parapet and other cantilever walls except retaining walls 1.

Exterior and interior ornamentations and appendages 1. Floors and roofs acting as diaphragms 2. Towers, chimneys , smokestacks and penthouses when connected to or forming part of a building.

Flat bottom tanks including contents attached directly to a floor at or below grade within a building. Division B Acceptable Solutions. NC R1. See Appendix A. See Subsection 2. E earthquake load and effects — a rare load due to an earthquake, as specified in Subsection 4. H a permanent load due to lateral earth pressure, including groundwater ,.

L live load — a variable load due to intended use and occupancy including loads due to cranes and the pressure of liquids in containers , as specified in Subsection 4. L XC live load exclusive of crane loads,. C live load due to cranes including self weight,. C d self weight of all cranes positioned for maximum effects,. C 7 crane bumper impact load,. P permanent effects caused by pre-stress,. S variable load due to snow, including ice and associated rain, as specified in Article 4.

T effects due to contraction, expansion, or deflection caused by temperature changes, shrinkage, moisture changes, creep, ground settlement, or a combination thereof see Appendix A , and.

W wind load — a variable load due to wind, as specified in Subsection 4. Table 4. Importance Categories for Buildings Forming part of Sentence 4. Log In. I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.
