It :was'•noted that easily .audible - (from the inside) 'creaking' sounds were emitted by the'building and these• appeared to coincide with regard to snow loads: ' We'have reviewed'the general' ss-secxion-- of--tbe�bu-il_d,_a ng-.a..nd method of construction' and• have formed the.opion that tills. Investigation The frames of this building are of an uncommon type, being a: two pinned arch: formed of solid. mem. bers at the`•lower.ends of the legs and a • trussed centre section.' The trussed centre section shows,, an. unusual feature is that at two 'places the. frame •is not completely. triangulated , there be ing one location eachside of the centre, • line where a diagonal 'member frames into the top 'chord some.' 2'0". from the 'closest vertical. •In preparing our calculations we have been guided by the require inerts' of the National Building Code 0265), . in Selecting allowable stresses and snow and: wind' loadings. It should be noted. that this code. is generally more severe than previous codes with (No. factor of safety) • (d) See item (c) above,, structure was never actually design- ed , but is the result of the builder's experience with previous, possibly smallerspan buildings of a similar type However , in our investigation We have had to assume that the build- ing is a designed structure and we have checked it in accordance with °•seneraily.accepted,engineering principles . Frames" analysed as a two hinged arch; - Case 1 Self Weight only. (a) Stresses in timber are within Code lirnits, - • (b) Foundations are stable. (c) The capacity of the member to member connections cannot be determined and is in doubt: Case 2 Self Weight plus Wind Force (a) Stresses in timber are gener- ally within Code limits. • •(b) The leg. timbrs in the 'leg joint' are severely ,overstressed . (c) Under wind forces the leeward column footing, is only: just stable • Case 3 Self Weight plus .Snow Load• (a)7, -the." -'leg joint is seriously overstressed . (b) Certain truss members are overstressed, • '(c) Foundations have insufficent factor of safety' with regard to stab- ility. . • •(d) The capacity of .the connect- ion; ,between the frameleg and the foundation wall (friction• only) is .in 'doubt.. • (e) See :(c) of Case 1. Case 4 Self Weight , Snow- Load Wind Force (a) For •these conditions the ~ ` leeward column footing is unstable 'Remarks 'As stated previously , • it is our op7. inion that, no structural design was ever prepared for, this building. It is thought; •However„ that the buil - d,ing harries were intended tp act' as a series of two hinged arches. Our, calculations show that the legs of the arches are ,not stiff enough for this to be.. possible and we have thereforegiVen some thought as to how -toe building has remained' stable. r TENDED 1:PAt-4E ell CTUAL F ' ACT/6W • If our, 'opinion the 'leg joints' have over the years., become suff ir':ienrly t1' xihle for the frame to_ act as shown. This means -that wherea ' the original frames: were intended .to resist wind, the'wind forces are, now transmitted 'through the sheeting, and framing to the end walls, and the frames now act 'as simple trusses supported on inclined legs.. The wired stresses in the;;end walls cannot be 'determined by any practical engineering analysis and due to, the method of construction *•of these walls, .neither can they be relied 'an to provide stiffness in the building indefinitely. ' bur' concern is that if the 'leg joints are to be stiffened, the whole• action of the frames will be:- changed e:changed making it:necessary to , investigate each member, joint and foundation. • • We have investigated the memb- ers and foundations of a typical frame with thetesults as shown earlier in this'•report. With regard to the joints, no 'investigation can . . :'be carried out, until a .complete - inspection of -each joint has . been made and the, design of the joint Checked.' • • Conclusion: • Considerable;' repair work 'to the''. structure would be, required to make the building conform to the present code. These •repairs are 'likely to .enconV pass the following' major items:.- ' (a) An engineering•s'ur\ey of each joint in each truss frame and repairs :or strengtt}ening as necess ary. : (This is' amajor project and'. • ' should 'not :be undertaken until' Council has considered.' this report). • (b) Repairs.to the leg joint .,• consist- . ing of connecting'on timbers each : side of the existing •leg members: .. .. my wife calls "Old 'Stoneface."
