Hetween Gdd Llnes 9 and 10 the 100' roof trusses on Ltnes P, P.5 <br /> and R arn dlfferent from the typical trussee on Lines P, P.5 and R. These <br /> ttuaees appear to be somewhat stronger than the typical Miaeea on Llnes P, P.5 <br /> ar.d R and no calculatlone apF+ear to have been provided for these non-typtcal <br /> �nu,yee, yye presume theee tnuses wem provid�d to accommodate higher <br /> gravity loade in thie area due to crane maintenance bay operationa. <br /> 2 - RP5160T. It seems section B/RFS500 should be cut looking at Lfne P rather <br /> than et Line P.5. <br /> 3 - Sheet S2I1. L�tall 1/5616 b celled out for the connectione of the hodzontel <br /> eWte to the wind columne�t the laadons of fulure crane croseovets. Th:s <br /> detaU does not teem to bnce the mu1H-story wtnd columns, C-7a and C-7b, <br /> adequately for Isteral to�lonal buckllng. We suggest diagonal colmnn Elenge <br /> bradng member be provided hom the inside Flange end of the column <br /> sNffener platea to the ahuls for torsional resis�ance. The connections and <br /> memyer 8�resses should ye ch¢cked for toraional buckling loads from <br /> referencee/texte on this eubject. <br /> 4 - Main Column Line Slevatlon on Sheet 5215. This elevaHon indicates B-5 or B- <br /> 10 beams at the Second Floor, whereas the plan on 2S500 appears to indlcate , <br /> &5 and B-6 beams. � <br /> 5 - Typical Croas SecNon at ]/4 and 3/4 Potnta on Sheet S2t5 and Typicat Croaa , <br /> Sectlon at ]/2 Pointa on Sheet 5216. Decail3/5612 Is called o�t for the i <br /> rnnditlon at the crane croseover and maintenance bay. However, thern la no f <br /> "from sheet" mark indksted in Detail3lSE12 and DetaU 3/5612 doea not seem <br /> to cover the conditlon to the actent shown indicated on these elevations. <br /> 1 <br />
