High-rise buildings of Risk Category III or IV, and All buildings more than 420 feet in building height. The purpose of this paper is to familiarize building owners and power system specifiers with the seismic compliance provisions of the IBC and how they apply to the design Each Occupancy Category has an associated Importance Factor, which is taken into account when determining a building’s structural reliability. For Risk Category II buildings, the wind-borne debris region is based on IBC Figure 1609.3(1). (Executive Order) 13717 • Cancels and replaces E.O.

Importance factors, I e, are shown in ASCE 7-10 Table 1.5-2. The original building has an occupancy of approximately 300, and the addition has an occupancy of approximately 400. Table 1604.5 in IBC-2015 lists the nature and occupancy of all risk categories. The arcane Table 1604.5, “Risk Category of Buildings and Other Structures” is located in IBC, chapter 16, section 1604.5 and has been located there since the inception of the first International Building Code (IBC) in the year 2000.

Structures in this category are used for services that are optional and/or where an extensive delay in Information about Risk Categories III and IV is taken from the above-mentioned table and reproduced below. The section is brief and relies on interpretation of the nature of occupancy in order to assign the appropriate risk category for design and analysis. 139 mph . Risk Category .

The percent reduction listed shall be applied to convert the : Risk category classifications are not consistent in the three editions of the IBC, and thus may vary from jurisdiction to jurisdiction depending on the edition adopted. A key item in the IBC 2015 regarding Wind-Borne Debris Regions that project teams may be misinterpreting, or missing2 all together, is that non-healthcare, Risk Category III buildings (e.g., schools) shall use the Risk Category II wind speed to determine if the project is in a wind-borne debris region. A copy of the table can be viewed on page 2. New definitions include “Greenhouse” and “Repair garage”.

STRUCTURAL REQUIREMENTS Basic Wind Speed: IRC - 110 mph (3-second gust) IBC - Risk Category I: V ult 130 mph . There are slight variations in the two codes but typically each will produce the same Risk Category. You can click on the map below to determine the seismic design category (SDC) and response parameter (S DS) for that location. The International Building Code (IBC) requires that critical systems and components must not only maintain structural integrity during an earthquake, but also remain operational and continue to carry out their primary functions (per 2015 IBC Chapter 17). As used throughout the code, the classification of an occupancy into a group is established by the require-ments of this chapter.

There is a direct relationship between the Occupancy Category and the Importance Factor—a low category will result in lower loads and a high category will call for an increase in loads. For WFCM wind load calculations, Minimum Design Loads for Buildings and Other Structures (ASCE 7-10) is used. The ninth edition building code was filed with the Secretary of State on Friday, Oct. 6, 2017 and became effective on Oct 20, 2017.
