" � - � <br /> Mr. William Flemer, ' <br /> , <br /> I � . . <br /> Reynolds Metals Company � <br /> Richmond, Virginia. <br /> f ' <br /> At your request we have performed an analysis of �he "CANBA,.vK" under a . ,, <br /> wind load of� 110 MPH. <br /> • The supporting structure has been analyzed as a space frame using a DEC <br /> computer and finite element analysis program with a mathmatical analysis <br /> of the structure. The skin has been utilized at the corners as a part of <br /> the corner cllumn structure. A printout is included being run first with <br /> the base channel flat IE: W�.ak axis horizontal; and 2nd run with the base <br /> channel set In edge and the strong axis horizontal. <br /> Calculations of the stress in the members was made using Specification for <br /> the design oi� cold formed steel structural members in light of the thin • <br /> sections used: The channels were analyzed as A-36 steel and checked if they ' <br /> werle 50 KSI yield steel. The skin attachment was checked against the code. � <br /> I � <br /> CONCLUSIONS: The structure as a whole has the structural integrity to withstand - <br /> 110 MPH winds' provided� that two modifications are made: <br /> � lo The corner skim m�st be attached to the angles making up ' <br /> i ! the co'rner columns at intervals of not over 3�". <br /> 2. The base channel must be placed on edge or reinforced to <br /> provide additional section modulus in the vertical axis. <br /> � <br /> It ,�s felt that the latter solution would be less costly than the amount of <br /> ( � <br /> attlachment oi! side pannels necessary for the skin the reinforce the channel as <br /> wel� as the question of the skin attachment of the skin on one leg only. <br /> � <br /> Submitted„for� Cobaugh Blanton Associates. <br /> `',�.V;:,C'``�•��'�1�.,�� � - <br /> --.� � ���--�� . <br /> ���� <br /> :R.
