Allowable Working Loads• The allowable working load in tension at the Superslim joints when bolted with 4 No.

M16x40 grade 8.8 set pins and nuts is 100kN, and the allowable bending moment is12kNm.

• When the Soldier is in bending at the joint only two of the bolts are fully loaded. Theremaining two bolts can take an allowable shear of 32kN per bolt or 64kN per joint.

• The joints and members are tested to validate the allowable working loads withmembers positioned in the worst tolerance cases where applicable.

• Representative load testing has been carried to establish allowable working loadsusing hire stock equipment to enable all imperfections and tolerances to be taken intoaccount. As the bending moment increases at the joint the internal forces are resistedby the bolts in tension at the tension face and by compression between the end platesat the other face. All bearing surfaces, including the bolt threads, undergo settlementand the bolts extend elastically. The joints on the soldiers under working loads mayhence open slightly at the tension face. This however is not detrimental to the jointperformance.

Tolerances at Joints• The flatness of the end plate of the Superslim Beam is square within 1 mm of the true

face, in either direction.

Required AssemblyTo achieve the allowable working load given above joints assembled on site shouldcomply with the following requirements:• The 4 bolts should be put in loose and then tightened in accordance with Eurocode 3

EN1993-1-1 section 7.5.6 making sure the soldiers are aligned with each other at thejoint by eye. This method will pull the end plates together adequately and replicate thevalidation tests.

• In accordance with the manufacturing tolerances check that a 1mm gauge cannot beinserted into the joint at any point around the joint perimeter

1.1.4. Beams with Compression Flanges RestrainedThe Super Slim Soldier is a lightweight member and it is not generally appropriate to use the principles ofBS449 or BS5950 for beam analysis. The performance envelope below has been derived from testresults. Research work undertaken using RMD Kwikform soldiers has shown that the performance isaffected by both shear stiffness and the bending stiffness of the member. Analysis of the beam fordeflection in this way is complex. For deflection calculation by simplistic analysis, a reduced EI value of3200 kNm2 gives good correlation with the more rigorous analysis. When used as a beam it is importantthat the soldier is restrained laterally at load points and supports. On a shutter, this lateral restraint isprovided by the backing members and face contact materials acting as a diaphragm. When used as anisolated beam it is normal to provide lateral restraint using scaffold tubes coupled to the flanges of thesoldier. When lateral restraint is not provided refer to 1.1.5 for Allowable Working Loads. When bending onthe weak axis, the soldier should be treated as two individual channel members, each with a moment ofresistance of 3.12 kNm. Individual loads act on the single section and transfer the forces through thestiffeners to the other channel.

The failure mode for long spanning beams without compression flange restraint tends to be by rollingover and buckling sideways of the compression flanges, a phenomenon known as lateral torsionalbuckling. During the design of standard steel sections reference is made to BS 449 table 3 and thepermissible bending stress is derated from the maximum for the material to ensure that failure of thisnature does not occur.Super Slim Soldiers are also susceptible to this kind of failure. The complex section is made up of twinchannels welded together in a manner that makes them act in a partially composite manner. The D/Tvalues also fall outside the BS 449 table. For these reasons a mathematical study has been combinedwith load testing to produce the graph below.

Effective Length of Compression Flange

BS 5975 Annex L.3 may be used to determine the effective length of the compression flanges.e.g. an individual Super Slim soldier cantilevers 0.9m past a Rapidshor U head. Determine themaximum point load that may be carried on the top flange at the unrestrained tip.

From BS 5975 table L3 the soldier is continuous with lateral restraint only. The effective length of thecompression flange (in this case the lower flange) is 7.5 * 0.9m = 6.75m.

From graph above maximum allowable bending moment at 6.75m effective length = 8.0 kNm. Hencemaximum point load at tip = 8.0 kNm / 0.9m = 8.89 kN.

1.1.6. Vertical Struts - Buckling About the Y AxisThe Super Slim Soldier, when used as a strut, has different loading characteristics about its two axes dueto its assymetric shape. The arrangement of the strut when erected may also dictate the method ofbracing to obtain the required capacity. The lateral stability of the struts in each direction requiresconsideration, and graphs of safe load capacity against effective strut length are given below. Theeffective length of a strut is defined in BS 449 section C, and BS 5975 table 33. When using the rockinghead the load is axial in one plane, but dependant upon site accuracy for the degree of eccentricity in theother plane; it is recommended that 25mm is the minimum eccentricity allowed. In the following graphsthe permissible loads are given allowing for eccentricity due to assembly tolerance and a load eccentricityof 25mm and 38mm. For vertical shoring applications the Effective Strut Length against AllowableWorking Load is given. For horizontal shoring applications the overall length of the horizontal shore againstthe Allowable Working Load is given.A load restriction of 100 kN is placed on the soldier when the load is to be released through the Slimshorjack, Where the load is not to be released through jacks, the maximum allowable load can be increased to150 kN.
