Although the basic structural and architectural components of industrial buildings are relatively simple, combining all of the elements into a functional economical building can be a complex task. General guidelines and criteria to accomplish this task can be stated. The purpose of this guide is to provide the industrial building designer with guidelines and design criteria for the design of buildings without cranes, or for buildings with light-to-medium duty cycle cranes. Part 1 deals with general topics on industrial buildings. Part 2 deals with structures containing cranes. Requirements for seismic detailing for industrial buildings have not been addressed in this guide. The designer must address any special detailing for seismic conditions. Most industrial buildings primarily serve as an enclosure for production and/or storage. The design of industrial buildings may seem logically the province of the structural engineer. It is essential to realize that most industrial build- ings involve much more than structural design. The designer may assume an expanded role and may be respon- sible for site planning, establishing grades, handling surface drainage, parking, on-site traffic, building aesthetics, and, perhaps, landscaping. Access to rail and the establishment of proper floor elevations (depending on whether direct fork truck entry to rail cars is required) are important con- siderations. Proper clearances to sidings and special atten- tion to curved siding and truck grade limitations are also essential.1. Dead load: This load represents the weight of the structure and its components, and is usually expressed in pounds per square foot. In an industrial building, the building use and industrial process usually involve permanent equipment that is supported by the struc- ture. This equipment can sometimes be represented by a uniform load (known as a collateral load), but the points of attachment are usually subjected to concen- trated loads that require a separate analysis to account for the localized effects.2. Live load: This load represents the force imposed on the structure by the occupancy and use of the building. Building codes give minimum design live loads in pounds per square foot, which vary with the classifi- cation of occupancy and use. While live loads are expressed as uniform, as a practical matter any occu- pancy loading is inevitably nonuniform. The degree of nonuniformity that is acceptable is a matter of engi- neering judgment. Some building codes deal with nonuniformity of loading by specifying concentrated loads in addition to uniform loading for some occu- pancies. In an industrial building, often the use of the building may require a live load in excess of the code stated minimum. Often this value is specified by the owner or calculated by the engineer. Also, the loading may be in the form of significant concentrated loads as in the case of storage racks or machinery. 3. Snow loads: Most codes differentiate between roof live and snow loads. Snow loads are a function of local climate, roof slope, roof type, terrain, building internal temperature, and building geometry. These factors may be treated differently by various codes. 4. Rain loads: These loads are now recognized as a sep- arate loading condition. In the past, rain was accounted for in live load. However, some codes have a more refined standard. Rain loading can be a func- tion of storm intensity, roof slope, and roof drainage. There is also the potential for rain on snow in certain regions.
