27 - Detall 5/S614. The bolta to the webs ot the diagonals are called out as <br /> A890 bolts. <br /> 27) Draftlng error will be corrected in the ne� revision. � <br /> 28 - Shest S615. Detail 7 irom Sheet S611 for Grid 9. <br /> a. The tlange pl�tes are indicated as being 12 inch wide, but the <br /> bsamt to whlch they connect are �nly 10 inches wlde. If the <br /> narrower width at ths beam can be �ustlfied, it seems the plates <br /> probably ahould be tapered. <br /> b. With the Interaectlon of the dlagonal and beam centerlinea located <br /> to the lett of the note "centerline symmetrical" it Is unclear from thla <br /> detell whether the brace to beam connectlon creates a concentric <br /> braced frame or an eccentric braced frame. Based on the <br /> calculations It le to be concentric. Hence, it seema the note <br /> centerline symmetrical" should be shitted to the left over the <br /> Intersection of the dlagonal and beam centerlinea. <br /> 28a) A note to taper these plates will be added to the detail tor the next <br /> revision. <br /> 28b) The centerline symmetrical will be moved for the next revision. <br /> 2� - DeUil 9/S61b. The bolta from the beam and gusset to the shear tab ars <br /> Called out a� A290 bolte. <br /> 29) Draiting error will be corrected in the next r2vision. <br /> 30 - Detall 2/S818 trom Sheet S618. With the vertical slotted holea in the <br /> connectlon plate for the wind column, it appears the wind load ehear In <br /> the column will creste cantilever bending In the connectlon above the <br /> column wlh the maximum moment at the centerline of the bottom chord of <br /> the roof trusaes. However, there does not appear to be any significant <br /> elements to resiat thia moment at the truss bottom chord level. Perhapa <br /> �ddftlon�l bracing Is needed. <br /> 30) At the roof truss bottom chords at Line R wide flange struts frame into <br /> shear tabs (see Section B/RFS502). This detail will take wind shear into <br /> the horizontal bracing system. <br /> 6 <br />
