NYC Admin. Code § 27-570 Earth pressures and foundation loads.
§ 27-570 Earth pressures and foundation loads.
The provisions of article three of subchapter eleven of this chapter shall apply.
Other Loads
NYC Admin. Code tit. 27, ch. 1, subch. 9, art. 6
in effectNYC Admin. Code § 27-571 Bins and bunkers.
§ 27-571 Bins and bunkers.
Loads on component parts of bins and bunkers may be reduced for friction on sidewalls, provided that sidewalls and supports are proportioned for the increased vertical loads. Where stresses would be increased in any component by arching of the fill, the effect of such arching shall be considered.
NYC Admin. Code § 27-572 Prestressing forces.
§ 27-572 Prestressing forces.
Prestressing forces shall be considered in the design of prestressed concrete structures, cable structures, guyed structures, and multiple intersecting truss webs utilizing tension members.
NYC Admin. Code § 27-573 Construction loads.
§ 27-573 Construction loads.
The provisions of subchapter nineteen of this chapter shall apply.
NYC Admin. Code § 27-574 Fluid pressures.
§ 27-574 Fluid pressures.
The design of building components shall consider pressures, both positive and negative, of confined fluids and gases.
NYC Admin. Code § 27-575 Ice.
§ 27-575 Ice.
The weight of a one-half inch radial thickness of ice on all surfaces shall be considered as part of the live load in the design of open framed or guyed towers.
NYC Admin. Code § 27-576 Thermal forces.
§ 27-576 Thermal forces.
The design of enclosed buildings more than two hundred fifty feet in plan dimension shall provide for the forces and/or movements resulting from an assumed expansion corresponding to a change in temperature of forty degrees F. For exterior exposed frames, arches, or shells regardless of plan dimensions, the design shall provide for the forces and/or movements resulting from an assumed expansion and contraction corresponding to an increase or decrease in temperature of forty degrees F for concrete or masonry construction and sixty degrees F for metal construction. For determining required anchorage for piping, the forces shall be determined on the basis of temperature variations for the specific service conditions. Friction forces in expansion bearings shall be considered.
NYC Admin. Code § 27-577 Shrinkage.
§ 27-577 Shrinkage.
The design of reinforced concrete components shall provide for the forces and/or movements resulting from shrinkage of the concrete in the amount of 0.0002 times the length between contraction joints for standard weight concrete, and 0.0003 times the length between contraction joints for lightweight concrete. The design of arches and similar structures shall provide for effects of shrinkage, plus rib-shortening, plus plastic flow.
