cantilevered ateel coluuaie and more expensive thazi the X-bracing. It ie <br />the only one of the solutions diacussed which would not affect the appearance <br />of the ehowroom, <br />4• SEP.VICE ENTRY AREA <br />4.1 Structural Descrintion <br />The Service Entry building ie two-etory frame coastruction. The upper <br />etory contains offices and ie of typical light frame conatruction, with <br />atud bearing walls and a flat roof framed with sawn rafters. The lowe: <br />etory ie wider [han the upper story nnd coneiets of joist supported on <br />glued laminated beams and frame bearing walls. <br />4.2 Structural Deficienciea <br />The only s[ructural deficiency in this area is the lack of sufiicient <br />reeietance to lateral forcea in the north-sauth direction. The uppe; <br />etory ie ligh[ and t}�e plywood sheathing which is typical on exterior <br />walls would provide sufficient lateral resistance for this story, However, <br />the lower story has only two frame walls in the north-south direction and <br />these are both interior walls with plasterboard on both sides and very little <br />capacity as ehear walls. <br />The upper floor provides sufficient atrength to carry t.he floor loads <br />from the offices as well ae the loade from the office bearing walls, even <br />when loaded at the joie[ midepan. <br />4.3 Feco�endations <br />Provide lateral resietance in the north-south direc[ion by sheathing [he <br />eaet wall o£ this area on ona side with plywooc?, installing framing anchors <br />at the top oE the wall and providing additional bolting to the slab at the <br />bot[om of the wall. <br />5 <br />� <br />� <br />i ?O j c�. :'�: _, :,a � c: . ,. �+ <br />
