Introduction Construction is usually used to refer to any project in the field. The fire resistance ratings for various types of construction for structural and non-structural members should be as given in . The structural system may be composed of three basic types of structures. Then look at chapter 6 for fire resistance rating requirements. Type A dwelling units are those that are required by and defined in the International Building Code. Load Bearing Structure. The height of a partition wall is determined by its function, which can be one storey or a portion of one level. What's the difference between Type A and Type B Construction? Despite the fact that in other types of building structures wood or steel is used as the main material, the construction of concrete structures uses reinforced concrete columns, concrete beams and concrete slabs for the construction of the supporting structure.

Conversely, a building is specifically a closed structure with a roof and walls. are all framed with wood. These buildings are frequently found in "warehouse" districts of older cities.
