7、al Building Code (2009 IBC) is adopted as the building code for DOD projects. UFC 3-310-04 supplements the requirements of UFC 1-200-01, General Building Requirements, by defining modifications to the 2009 IBC related specifically to seismic design of buildings. In the following narrative, required
8、modifications to the provisions of the 2009 IBC are listed. The modifications are referenced to specific sections in the 2009 IBC that must be modified. Any section in the 2009 IBC that is not specifically referenced shall be applied as it is written in the 2009 IBC. The 2009 IBC adopts by reference
9、 extensive portions of ASCE/SEI 7-05, Minimum Design Loads for Buildings and Other Structures (ASCE 7-05). This UFC modifies some sections in ASCE 7-05 in the same manner as is described for the 2009 IBC. An example section number in this chapter is 2-1603.1.5 or 2-13.6.7. The first number, 2, refer
10、s to Chapter 2 of this UFC. 1603.1.5 refers to 2009 IBC Section 1603.1.5 and 13.6.7 refers to ASCE 7-05 Section 13.6.7. It is expected that designers may highlight or otherwise mark those paragraphs of the 2009 IBC, RP 8, and ASCE 7-05 that are modified by this UFC. The required 2009 IBC, RP 8, and
11、ASCE 7-05 section modifications are one of four actions, according to the following legend: Addition New section added, includes new section number not shown in the 2009 IBC, RP 8, or ASCE 7-05. Deletion Delete referenced 2009 IBC, RP 8, or ASCE 7-05 section. Replacement Delete referenced 2009 IBC,
12、RP 8, or ASCE 7-05 section and replace it with the narrative shown. Supplement Add narrative shown as a supplement to the narrative shown in the referenced section of the 2009 IBC, RP 8,or ASCE 7-05. In a number of instances, provisions of ASCE/SEI 7-10, Minimum Design Loads for Buildings and Other
13、Structures, are adopted herein. These adopted provisions represent substantive changes from ASCE/SEI 7-05 to ASCE/SEI 7-10. With the tri-services adoption of the 2012 International Building Code (2012 IBC), the ASCE/SEI 7-10 provisions will be adopted by reference, and those provisions will no longe
14、r be listed in future editions of this UFC. 2-16 STRUCTURAL DESIGN 2-1603 CONSTRUCTION DOCUMENTS 2-1603.1.5 Supplement Earthquake Design Data. Item 2 covering mapped spectral response accelerations shall be modified to indicate the source of the acceleration data, including source date and author. I

Additions, alterations, repa
28、irs, changes of occupancy, relocations, or acquisitions of existing buildings or portions of existing buildings shall be in accordance with 2009 IBC Chapter 34 as modified by this Chapter. C 2-1613.3 Supplement Existing Buildings. IBC section 1613.3 was changed in the 2009 IBC to resolve confusion a
29、nd potential conflict between Chapter 16 and Chapter 34. Its only purpose is to direct users to Chapter 34.

Ground motion accelerations, represented by response spectra and coefficients derived from these spectra, shall be determined in accordance with the procedure of ASCE 7-05 Sections 11.4.1-11.4.5, or the
32、 site-specific procedure of ASCE 7-05 Section 11.4.7. Subject to approval by the Authority having Jurisdiction, a site-specific response analysis using the procedure of ASCE 7-05 Section 11.4.7 may be used in determining ground motions for any structure. Such analysis shall include justification for
33、 its use in lieu of the mapped ground motion data that are described below. A site-specific response analysis using the procedures of ASCE 7-05 Section 11.4.7 shall be used for structures on sites classified as Site Class F (see 2009 IBC Table 1613.5.2), unless the following condition is applicable:
34、 Both the mapped Maximum Considered Earthquake (MCE) spectral response acceleration at short periods, Ss, is less than or equal to 0.25, and the mapped MCE spectral response acceleration at 1-second period, S1,is less than or equal to 0.10, as determined in accordance with UFC 3-301-01.

The design and detailing of the components of the seismic force-resisting system shall comply with the applicable provisions of A
37、SCE 7-05 Section 11.7 and ASCE 7-05 Chapter 12, as modified by this UFC, in addition to the nonseismic requirements of the 2009 IBC. Note that this section is superseded by Section 4-11.1 of this UFC for OC V structures. 2-11.2 Replacement DEFINITIONS - DESIGNATED SEISMIC SYSTEMS. Provided by IHSNot

39、ordance with Chapter 13 and for which the component importance factor, Ip, is greater than 1.0. This designation applies to systems that are required to be operational following the Design Earthquake for OC II, III, and IV structures and following the MCE for OC V structures. All systems in OC V fac
40、ilities designated as MC-1 (see Chapter 4) shall be considered part of the Designated Seismic Systems. Designated Seismic Systems will be identified by Owner and will have an Importance Factor Ip = 1.5 for OC II, III, and IV structures. 2-11.2 Replacement DEFINITIONS - IMPORTANCE FACTOR. A factor as
41、signed to each structure according to its Occupancy Category as prescribed in UFC 3-301-01 Table 2-2. 2-11.5.1 Replacement Importance Factor. A seismic importance factor, I, shall be assigned to each structure in accordance with UFC 3-301-01 Table 2-2. Importance factors for wind load, snow load and
42、 ice load, as applicable, shall also be assigned to each structure in accordance with UFC 3-301-01 Table 2-2. Note that this section is modified by Section 4-11.5.1 of this UFC for OC V structures. 2-11.7 Supplement Design Requirements for Seismic Design Category A. ASCE 7-05 Section 11.7 shall not
43、apply to buildings in OC V. 2-12.6 Supplement Analysis Procedure Selection. Table 2-2, Replacement for ASCE 7-05 Table 12.6-1, shall be used in lieu of ASCE 7-05 Table 12.6-1. Note that this section is superseded by Section 4-12.6 of this UFC for OC V structures. 2-12.8 Supplement Equivalent Lateral
44、 Force Procedure. When the ELF procedure is used, provisions of ASCE 7-05 Section 12.8 shall be used. This procedure may be applied to the design of buildings in OCs I through IV as permitted by Table 2-2. C 2-12.8 Supplement Equivalent Lateral Force Procedure for Seismic Design of Buildings. The EL
45、F procedure is the primary design method for seismic design of military buildings. Several restrictions on using the ELF procedure for buildings in SDCs D - F are imposed by Table 2-2. These restrictions are predicated on the presence of Provided by IHSNot for ResaleNo reproduction or networking per

The Simplified Design Procedure (SDP) of ASCE 7-05 Section 12.14 is a simplification of the ELF procedure that may be applied to low-rise buildings that meet a set of pre-conditions given in ASCE
47、7-05 Section 12.14. The SDP adopts a more conservative design approach than the ELF procedure. 2-12.8.7 Replacement P-Delta Effects. Replace Equation 12.8-16 with the following: 16)-(12.8 dsxxxChVIP = C 2-12.8.7 Replacement P-Delta Effects. Equation 12.8-16 is adopted from ASCE 7-10. Equation 12.8-1
