The live loads specified in Sections 1607.3 through 1607.10 shall be assumed to include adequate allowance for ordinary impact conditions. Provisions shall be made in the structural design for uses and loads that involve unusual vibration and impact forces.
1607.11.1 Elevators
Members, elements and components subject to dynamic loads from elevators shall be designed for impact loads and deflection limits prescribed by ASME A17.1/CSA B44.
1607.11.2 Machinery
For the purpose of design, the weight of machinery and moving loads shall be increased as follows to allow for impact:
  1. Light machinery, shaft- or motor-driven, 20 percent.
  2. Reciprocating machinery or power-driven units, 50 percent.
Percentages shall be increased where specified by the manufacturer.
1607.11.3 Elements Supporting Hoists for Façade Access and Building Maintenance Equipment
In addition to any other applicable live loads, structural elements that support hoists for façade access and building maintenance equipment shall be designed for a live load of 2.5 times the rated load of the hoist or the stall load of the hoist, whichever is larger.
1607.11.4 Fall Arrest, Lifeline, and Rope Descent System Anchorages
In addition to any other applicable live loads, fall arrest, lifeline, and rope descent system anchorages and structural elements that support these anchorages shall be designed for a live load of not less than 3,100 pounds (13.8 kN) for each attached line, in any direction that the load can be applied.
Anchorages of horizontal lifelines and the structural elements that support these anchorages shall be designed for the maximum tension that develops in the horizontal lifeline from these live loads.
