From order to execution• For simple scaffolds• For complex sacffolds

How do you work?• What do users need?• What do users need?• What is the vision

Realization of the vision• Integrating processes• The “Scia Scaffolding Suite”

Results of this vision• Advantages

Current process in scaffolding companiesCurrent working method up to the order

Requests• Lots of requests for quotation

Type of scaffold

• Simple or complex scaffold?scaffold

Simplescaffold

• Needs fast and precise bill of material and prices• Nice presentation is an extra sales argument

Reality

• Often no drawing, no calculation checks• Price based on rough estimations and experience

3

Current process in scaffolding companiesCurrent working method for complex scaffolds … up to the

order

Complexscaffold

• In general … More details are needed• Drawings, survey on site, basic / advanced checks

Drawing

• Drawings, cuts, views …• Currently often in 2D

Checks

• Currently based on manufacturers tables• Currently simple 2D checks on some critical points

Quantities

• Choice of scaffold elements (tubes, couplers …)• Price based on estimation of quantities

NOT OK

� Current method of design

2D constructions

Linear analysis

Effective length method

Focus on safetyIncrease safety in scaffolding – calculation rules

� Internal forces derived from

1st order analysis

� Design according

Relevant design code (e.g. EC3)

19

� Complexity of scaffolds

High degree of non-linearity

Large deflections

� Non-linearities


Couplers (non-lin. behaviour)

Base jacks (friction)

Excentricities (bracings)

� Large deflections

2nd order effects very important

Inclined scaffold (also base jacks)

Vertical loading → horizontal loading

20

� New prescriptions (EC 12811)

• Non-linear coupler behaviour

• 2nd order is the preferred way ofanalysis

• Equilibrium of the displaced systemis taken into account directly


is taken into account directly

• Global effects (P-∆) = buckling

• Local effects (P-δ) = bow-imperfection

• Perform section check only

• Stability

• Generates buckling form

• Includes P-∆ and P-δ

• Input for 2nd order calculation

� Diagonals







48

� Floorboards

• Wooden planks → additional loading

• Metal → include spring stiffness

� Base jacks

• Not fixed to the ground → uplift

• Hor. resist. = f (vert. load) → friction

� Anchorages, abutments

• Fixed, pressure only …

� General

• Check in service → high working, minor wind loading

• Out of service → extreme wind, material on the scaffold

Vision to better processes in scaffoldingYour advantages in a nutshell

• Exact, fast and complete solution• In every stage of the process

Completeness

• General or tailor-made solution• For every kind of user (commercial, builder, technician …)

Versatility

• For every kind of user (commercial, builder, technician …)• Create your own librairies and templates (company style)

• In full compliance with newest codes and prescriptions EN 12810-12811• Import and export with industry standards (DXF, DWG, PDF, XML, IFC …)

Safe and open interface

• Integration in one environment leads to proven time-saving• Simple and fast changes in one place lead to automatic update of all documents

Time-saving and profitability
