involve several different types of framing systems, which include steel arches, cable-hung frames, and other types of systems. These methods are beyond the scope of this TRAMAN.

PRE-ENGINEERED METAL STRUCTURES

Pre-engineered metal structures are commonly used in military construction. These structures are usually designed and fabricated by civilian industry to conform with specifications set forth by the military. Rigid-frame buildings, steel towers, communications antennas, and steel tanks are some of the most commonly used structures, particularly at overseas advanced bases. Pre-engineered structures offer an advantage in that they are factory-built and designed to be erected in the shortest amount of time possible. Each structure is shipped as a complete kit, including all the materials and instructions needed to erect it.

Of the pre-engineered metal structures available, the one that is perhaps most familiar to the Seabees is the pre-engineered metal building (PEB) shown in figures 8-53 and 8-54. Figure 8-53 shows the nomenclature of the various parts of the PEB. For definition of this nomenclature, erection details, and other important information regarding the PEB, you should refer to the Steelworker, NAVEDTRA 12530.
