Introduction

Comprising of a number of different lengths of leg extension and a range of accessories which bolt simply together at

the joints, the Tubeshor 610 hybrid hydraulic tubular shoring system is used for propping waling beams or capping

beams of large excavations and for vertical applications such as bridge bearing replacement. An integral hydraulic

ram unit is rated for an AWL of 2500kN rising to 4500kN once the unique mechanical lock off collar is engaged. High

rotation Swivel Units have an AWL of up to 4750kN and innovative Spherical Bearers 5000kN. If hydraulic adjustment/

preloading are not required, a comprehensive range of accessories is available to facilitate reduced cost options for

versatile and economical longer term propping solutions.

Design to EN Standards

The RMD Kwikform Tubeshor 610 Brace has been designed in accordance with EN14653, manufactured in

accordance with EN1090 and all components carry CE marking.

To facilitate a simplified scheme design using established permissible load methods, load performance data in this

document is displayed as an ‘Allowable working load’. Should Limit State Design be required, the Design Resistance

may be obtained by multiplying the Allowable Working Load values by 1.5.

When used at the end of a horizontal prop, these units undergo bending and shear actions as well as axial loads. The

graph below enables local checks to be carried out for the three duties of Tubeshor Weldable Stubs when fitted at the

ends of horizontal Tubeshor 610 props with either pinned or fixed end conditions. For the overall strut performance use

the lower value taken from this graph and the graphs on pages 20-22.

Weldable stubs should be site welded to embedded steelwork or custom structural steel waling beams. It is not likely

that that trimming of the stub will be accurate enough to enable the loads to be transferred directly between the stub

and the supported steel and so all loads are carried by the site welding. When the stub is fully loaded as determined by

the graph below, the weld leg length should equal 1.4 times the stub tube thickness. When the prop is loaded below

the maximum the weld size may be proportionally reduced accordingly.

APPLICATIONS

Structural Parameters To facilitate a simple scheme design using established permissible load methods, performance data is displayed as an

Allowable Working Load. Should limit state design be required, minimum Design Resistances may be obtained by

multiplying Allowable Working Loads by 1.5.

Graph values have been obtained using non-linear second order analysis including all relevant load actions,

geometric imperfections and bolted joint limitations. Limit State is reached at the onset of first elastic yield.

Ground Shoring Applications Horizontal or inclined props are arranged such that they restrain one or both sides of an excavation. In this mode

Tubeshor props are designed to comply with EN14653: Manually Operated Hydraulic Shoring Systems for Groundwork

Support, EC3: Design of Steel Structures and CIRIA C760: Guidance on Embedded Retaining Wall Designs.

Boundary Conditions

Props are modelled as simply supported having pinned ends with end axial loads applied with an eccentricity of either

50mm (10% of the end fitting in accordance with CIRIA C760) or 0mm depending on end fittings and orientation.

Geometrical Imperfections

An initial out of straightness of the overall prop of L/350, acting either up or down has been used. This value was

obtained from the raw material out of straightness of L/500 plus an allowance for additive tolerance during

manufacture; assembled props have been found to be much straighter than this.

A reduced flexural stiffness and strength for the bolted joints (established by 3D modelling backed up by full scale load

testing) has been taken into account. Correct modelling of the bolted joints between components is pivotal in

determining the correct strut curves.

The option to add one or two pre-camber shims of fixed 0.5° angle bolted between ring flanges near mid span has

been included which reduces self weight deflection and thus second order effects.

Load Actions and Partial Factors

A material factor of 1.1 has been used on resistance properties (moment and axial).

Self-Weight (Gk) is represented by a uniformly distributed load of 2.2 kN/m with a partial load factor 1.35

Geotechnical Loading (Gk,GEO) is applied with a partial load factor of 1.5

Accidental Loading (Qk,accidental) of either 0kN, 10kN or 20kN acts as a central point load with a partial load factor of 1.0




Date: 12/12/2017 Issue : TG01


APPLICATIONS

Thermal Loading

Where appropriate thermal loading (Qk,temp) is considered separately and covers cases where the screw collar on the

Tubeshor Hydraulic Unit is locked down or raised.

Thermal Loading with the Screw Collar Locked

The load path is through the steel components of the prop. The Hydraulic unit is axially stiffer than the Tubeshor

extensions and this is evident by the rise in the thermal effect for shorter length props in charts T1 and T2.

Thermal Loading with the Screw Collar Raised

The axial load bypasses the casing of the Hydraulic Unit and passes instead through the hydraulic cylinder including

the column of hydraulic oil which has a bulk modulus (volumetric stiffness) 130 times lower than the elastic modulus of

steel. As a result props with raised screw collars have significantly less axial stiffness compared to those with the collar

locked, the stiffness of the hydraulic oil dominates and thermal loading values, which are now independent of prop

length, are shown as a table of values below.

Thermal Loading can be as a result of direct solar gain, daily temperature range, seasonal temperature variations or a

combination of all three. The thermal expansion coefficient of hydraulic oil is 58 times higher than for steel, making

temperature range for the oil also significant. The oil is buried within the confines of a hydraulic cylinder having 25mm

thick steel walls, itself encased in still air within a steel casing having 25/40mm thick walls. As a result the change in

temperature in the oil will lag behind that of the Tubeshor prop body.

For long term propping (over 3 months duration) it can be assumed that the temperature variation in the oil is equal to

that in the prop body. For short term propping (less than three months), solar gain and daily temperature variations will

take precedence over seasonal variation and the comparatively short period of these fluctuations and the confinement/

insulation of the mineral oil means that the temperature range in the mineral oil can be taken as 50% of that in the prop

body. Some competitors ignore the thermal expansion of the mineral oil and figures are also given below for this case.

Thermal load graphs include options for the stiffness factor for the supported wall - bof 0.3 appropriate for use with

sheet piled excavations or bof 0.5 appropriate for use with stiffer diaphragm or secant piled walls.

APPLICATIONS

Loading Combinations

In many markets it is not usual to allow for thermal loading but where this is required the results from the axial load and

thermal load charts can be combined in the following load cases from which the lowest allowable working load will

govern. This is the approach used in CIRIA C760:Guidance on Embedded Retaining Wall Design.

LC1: 1.35Gk + 1.35Gk,GEO + 0.9Qk,temp

LC2: 1.25Gk + 1.25Gk,GEO + 1.5Qk,temp

LC3: 1.0Gk + 1.0Gk,GEO + 1.0Qk,accidental + 0.6Qk,temp

Example Calculations

Check the suitability of a 15m long, non pre-cambered Tubeshor 610 knee brace with the screw collar raised and

having Swivel Units both ends with the pivot pins vertical is to be designed for an accidental load of 10kN and a

thermal range of 20°C in a sheet piled excavation.

Applied Load PSLS = 1500kN

Qk,temp = 347kN

From CIRIA C760, Section 8.1.6

LC1: 1.35Gk* + 1.35Gk,GEO + 0.9Qk,temp

1.35 x 1500 + 0.9 x 347 = 2338kN

LC2: 1.25Gk* + 1.25Gk,GEO + 1.5Qk,temp

1.25 x 1500 + 1.5 x 347 = 2396kN

LC3: 1.0Gk* + 1.0Gk,GEO + 1.0Qk,accidental* + 0.6Qk,temp

1.0 x 1500 + 0.6 x 347 = 1710kN

* contributions from prop self weight and accidental load are already included in the load charts.

For LC1 and LC2, using graph 610/H7. AWL = 1920kN

(To obtain design resistance, multiply by partial factor of 1.5) = 2880kN > 2396kN OK

For LC3, using graph 610/H8. AWL = 1820kN

(To obtain design resistance, multiply by partial factor of 1.5) = 2730kN > 1710kN OK

Vertical Shoring Applications Use of the Tubeshor 610 Spherical Bearer ensures concentric loading. Where the Tubeshor 610 Swivel Unit is used, a load ec-

centricity of zero has been used in one axis and 50mm in the other. We recommend that for loads in excess of 50% of the allowa-

ble prop working load, grouting should be used between the Swivel Unit end plate and a concrete foundation.

Vertical load charts include data for dynamic wind pressure q ranging from 0-3kN/m2
