! i Mr. Art Skotdal Skotdal Real Estate Plan Check Number: B1906-031, Second Building Review - Structural October 18, 2019 24.The comment has not been addressed. The response is not sufficient to address the comment. The submitted calculations only appear to represent a single beam, though the dimensions in the calculation are not consistent with any of the cross-sections. Calculations representing each condition shall be provided for review. Where steps and sloping surfaces occur in the beams along their lengths, the design of the beam shall incorporate these conditions. Where a reduced cross-section is considered, the addition beam cross-section shall be included in the design loads. The original comment has been provided below with revisions. Additional review comments may be provided pending review of the design. The L1 slab on Sheet S2.07 includes transfer beams CB36x22* at Grids 5.3/A-D and 7/A-D, and CB24x64* at Grid 6.4/A-D; the significance of the"*"does not appear to be defined. The project also includes additional beams CB24x64* at Grid 6.4/D-F on Sheet S2.07, CB24x24 and CB13.5x24 at Grids 4/G-J and 4.9/G-J, respectively, on Sheet S2.03, and in Section 2/S3.00. The following comments shall be addressed: a. Calculations substantiating the beam design shall be submitted for review. The design shall consider the load combinations per ASCE 7-10 Section 12.4.2.3 including the vertical seismic load effects per Section 12.4.2.2. b. Details for the beams, including the end connections to the supports and the required reinforcement, shall be included in the structural drawings. See IBC Section 1604.1 and 1901.5 Item 3. Note that the sections on Sheet S6.02 are generally not consistent with the beam sizes indicated on the plans. c. Section 1/A6.02 indicates a larger beam beyond. This beam does not appear to exist on the plans. d. Beam CB36x32 on Section 3/S6.02 includes an unspecified dimension below the"6-inch NOTCH"dimension. The dimension shall be specified. e. The beams in Section 1/S3.00 and on Sheet S6.02 specify various reinforcement per "schedule". A schedule does not appear to be provided in the drawings. f. Beam CB13.5x24 is shown with a varying depth in Section 1/S3.00. It appears that the bottom of the beam may not coincide with the slab south of Grid 4.9. The interconnection of the slab and beam is not clear. 25. No additional comment. 26. No additional comment. 27. No additional comment. 28. No additional comment. 29. No additional comment. 30.
