Plan Check 1727- Larry Callahan August 9, 1985 Page Seven II. Size and spacing of bridging for the roof open web joists should be provided as recommended by SJI. Section 2714 and UaC Standard 27-4. At least 3 rows of bridgin9 are required for the typical 20H5 joists which span 's0' . 9. The calculations should be submitted which detennine tiie magnitude of the floor and roof diaphragm shears, particularly adjacent to the ductile moment resisting bays. Tiie adequacy of the diaphragms and their connections should be justified by calculations. Continuous chord members should be detailed. Section 2303(b)1. The roof deck connections should be shown on the plans. 20. Our review cannot be completed at this time, because several areas of the proposed structure contain no details. 5tructural details for the follo�aing items should be submitted to verify compliance with code provisions. Section 302(b) . Additional comnents may be forthcoming. a. All stairs. b. All exterior skylights and canopies, including wind uplift resistance on all elements (including the skylights themselves). Section 2311(e,f) c. Connections of skewed beams as shown on �heets S-3 through S-6. ; d. Curtain wall contruction, including design for vertical loads, wind � pressures inward and out�aard, and ductility of connections as requireC by Section 2312(j)C, i .e. 4.5 x calculated story drift. e. Suspended accoustical ceiling support for seismic loads. Table 23-J, Section 4i01(f), UBC Standard 47-2 f. Bridge at south entry. g. Guard rails per Table 23-B (50 plf lateral loading on handrail ). h. Section cuts on roof framing plan and addition of appropriate related details of the roof framing showing how the various beams, columns, and joists interconnect, how roof overhangs are framed, etc. i . Details of high strength bolting. What quality control procedures are proposed, such as proof-loading and inspection of bolts, load- indicator bol�s or washers, etc.? Section 2713, and UBC Standard 27-7 j. Framing member sizes and connection details around roof inechanical openings. I
