Sample text

Galvanized Steel — Painted (Duplex System) Sometimes it is desirable to provide a coating system for steel that includes both galvanizing and paint systems. There are several reasons why it would be desirable to combine these materials: aesthetics, color coding, safety markings, ease of repairing, and low life-cycle costs are just a few. This combination of galvanizing and paint systems is known as a duplex system. The key to success of a duplex system is proper surface preparation and proper selection of a paint system.

The building's service requirements may determine that little or no protection of the steel is necessary at all. Steel does not rust except when exposed to atmospheres above approximately 70 percent relative humidity. Serious corrosion of steel occurs at normal temperatures only in the presence of both oxygen and water. In dry atmospheres (less than 70 percent relative humidity), non-painted steel can be exposed for extremely long periods of time with no evidence of rusting. If the steel is not painted, a thin transparent film of iron oxide forms on the non-painted steel, actually protecting the steel from further corrosion.

Periodic loads are caused by rhythmic human activities such as dancing and aerobics, and by impactive equipment. Transient loads occur from movement of people and include walking and running. Single jumps and heel-drop impacts are examples of impulsive loads. Period and Frequency. Period is the time, usually in seconds, between successive peak excursions in repeating events. Period is associated with harmonic (or sinusoidal) and repetitive time functions as shown in Figures 18a and 18b. Frequency is the reciprocal of period and is usually expressed in Hz (Hertz or cycles per second).
