Ity as defined in ASCE.Users and Designers of Special Structures free PDF ebook.For Site Class E sites with S1 ≥ 0.2 – values in italics may be used provided that the structures period T ≤ TSAnd the Equivalent Lateral Force (ELF) procedure is used for design.Chapter 8 – Diaphragm Design & Wall RigidityAlternative Design Provisions for Diaphragms, etc.The alternative design provisions for diaphragms, including chords and collectors of ASCE 7-16 – Precast concrete diaphragms in structures assigned to SDC = C, D, E or F Precast concrete diaphragms in structures assigned to SDC = B Cast-in-place concrete diaphragms assigned to SDC = B, C, D, E or F Wood-sheathed diaphragms supported by wood framing assigned to SDC = B, C, D, E or FDiaphragms, including chords, collectors, and their connections to the vertical elements, shall be designedIn two orthogonal directions to resist the in-plane design seismic forces determined in ASCE 7-16 –NOTE: The provisions of ASCE 7-16 – §12.10.3 are rather complicated and are considered to be beyondThe scope of the seismic principles exam, and therefore are beyond the scope of this workbook. For Site Class D sites with S1 ≥ 0.2 – values in italics may be used provided Cs is determined by ASCE 7 (12.82) for values of T ≤ 1.5TS and taken as 1.5 times ASCE 7 (12.8-3) for 1.5TS TL ).2. Where the alternative simplified design procedure of ASCE 7-16 isUsed, the Seismic Design Category (SDC ) shall be determined in accordance with ASCE 7-16 – §12.14.Table 3.2 - Design Spectral Response Acceleration Parameter at 1-Second Period (SD1)Values shall be determined per ASCE 7-16 – § 21.11. 9 - ASCE 7 – Figure 11.4-1)Determination of Seismic Design Category, SDCThe Seismic Design Category (SDC ) of a structure is used to determine the following: Permitted seismic force-resisting systems (SFRS) Restrictions on buildings with horizontal and/or vertical irregularities Requirements for nonstructural componentsNOTE: The Seismic Design Category (SDC ) for a structure is permitted to be determined in accordanceWith IBC §1613.2.5 or ASCE 7-16. Apply the footnotes as applicable including the use ofSite Class D (default) when that site class is assumed (i.e., no geotechnical report).Figure 3.1 – Design Response Spectrum (Ref. These tables should not be used if Fa & FvAnd/or SMS & SM1 are required to be determined.The relative cantilever wall rigidities are determined for each shear wallUsing their respective H/D ratios and Table D1 - Relative Rigidity of Cantilever Shear Walls / PiersThe inherent torsional moment is then equal to the story shear times the calculated eccentricity asWhere diaphragms are not flexible (i.e., rigid or semi-rigid), the distribution of lateral forces at each levelShall consider the effect of the inherent torsional moment (Mt) … plus the accidental torsional moments(Mta) caused by … the accidental eccentricities. 1-83 & 84), which considers the seismic load effects including overstrength factor (Ω0) of ASCE 716 – §12.4.3.ASCE 7-16 – §12.10.2.1 allows two an exceptions: (drag) forces calculated from Fpx maximum per ASCE7 equation (12.10-3) using ASCE 7-16 – §12.4.2.3 load combinations and for structures braced entirelyBy light-frame shear walls (i.e., wood studs or cold formed steel studs) … with drag forces determinedFrom the governing Fpx force per ASCE 7-16 (12.10-1), (12.10-2) and (12.10-3).Figure 8.12 – Cantilever Shear Wall / PierRigidity is proportional to the reciprocal of deflection and is essentially the relative stiffness of the lateralMasonry & concrete shear walls resist lateral loads in proportion to each walls rigidity (R), therefore only"relative rigidities" are needed. Numerical rounding of theCalculated unit diaphragm shear and unit wall shear may result in drag forces that do not quite “zero” atTypically, the wall top plates (at the diaphragm boundary) are used as the chords and collectors for woodCollector elements shall be provided that are capable of transferring the seismic forces originating in otherPortions of the structure to the element providing resistance to those forces (e.g., shear walls, bracedIn structures assigned to SDC = C, D, E or F - collector elements and their connections includingConnections to vertical elements (e.g., shear walls, braced frames, moment resisting frames, etc.) shall beDesigned to resist the maximum of the forces determined from ASCE 7-16 – §12.10.2.1 items 1, 2 and 3(see p. Each line of vertical elements of the seismic force-resisting system (SFRS) complies withThe allowable story drift of ASCE 7 Table 12.12-1Diaphragms of concrete slabs (or concrete filled metal deck) with span-to-depth ratios of 3 to 1 or less(i.e., L/d ≤ 3) in structures having no horizontal irregularities are permitted to be idealized as rigid.The drag force should always be equal to zero at each end of the collector. Topping of concrete or similar materials is not placed over wood structural panel (WSP)Diaphragms except for nonstructural toppings ≤ 1½ inches thick2.
