3. 23/10/02TIS/TE-MC Gonzalo Micó Montava3 Gantry and Crane Model The new model geometry Weight of the Muon Chambers: 47.4T (S.L.) Weight of the Preshower: 22.42T (S.L.) Nominal Load of the Crane: 30T (Var.L.) EuroCode 3 Standard Steel (S235JR) 4 5 52 92 93 28 28, 34, 35, 86  Nodes 4, 5, 52, 92, 93  Bars 34 35 86 Own weight (Static Load)

4. 23/10/02TIS/TE-MC Gonzalo Micó Montava4 Static Case Results Reactions Stresses The Maximum Reaction is in Node 28 (Point fixed to the wall) The Maximum Total Normal Stress is in Bar 52 (Support Beam of the Crane) Smin  Minimum Total Normal Stress Smin (My)  Minimum Bending Stress due to axis y Smin (Mz)  Minimum Bending Stress due to axis z Smax  Maximum Total Normal Stress Smax (My)  Maximum Bending Stress due to axis y Smax (Mz)  Maximum Bending Stress due to axis z Fx/Ax  Axial Force Smax = Smax(My)+Smax(Mz)+Fx/Sx

5. 23/10/02TIS/TE-MC Gonzalo Micó Montava5 Static Case Results Work Ratio (Ultimate Limit State Verification) (ULS) Displacements (Serviceability Limit State Verification) (SLS) The Maximum Work Ratio is 0.95 in bar 93 (Preshower) The Maximum Displacement is in bar 93 (Preshower) (EuroCode 3, paragraph 4.2.2)

6. 23/10/02TIS/TE-MC Gonzalo Micó Montava6 Seismic Analysis The Seismic Analysis was performed for the working position  Crane is parked far away Weight of the Muon Chambers: 47.4T (Acc. L.) Weight of the Preshower: 22.42T (Acc. L.) EuroCode 3 PS 92 4 5 52 92 93 28 28, 34, 35  Nodes 4, 5, 52, 92, 93  Bars 34 35 Own weight (Acc. Load)

7. 23/10/02TIS/TE-MC Gonzalo Micó Montava7 Seismic Case Results Reactions Stresses The Maximum Reaction is in Node 34 and 35 (Point fixed to the ground) The Maximum Total Normal Stress is in Bar 52 (Support Beam of the Crane) Smin  Minimum Total Normal Stress Smin (My)  Minimum Bending Stress due to axis y Smin (Mz)  Minimum Bending Stress due to axis z Smax  Maximum Total Normal Stress Smax (My)  Maximum Bending Stress due to axis y Smax (Mz)  Maximum Bending Stress due to axis z Fx/Ax  Axial Force Smax = Smax(My)+Smax(Mz)+Fx/Sx

8. 23/10/02TIS/TE-MC Gonzalo Micó Montava8 Seismic Case Results The Maximum Work Ratio is 0.95 in bar 93 (Preshower) Work Ratio (Ultimate Limit State Verification) (ULS) Displacements (Serviceability Limit State Verification) (SLS) The Maximum Displacement is in bar 93 (Preshower) (EuroCode 3, paragraph 4.2.2)

9. 23/10/02TIS/TE-MC Gonzalo Micó Montava9 Static and Seismic Analysis Conclusions: All bars fulfil the EuroCode 3 for Static and Seismic CaseAll bars fulfil the EuroCode 3 for Static and Seismic Case Nominal Load of the Crane must not exceed 30TNominal Load of the Crane must not exceed 30T Remarks: Connections have not been verified The bar 93 (Preshower) Working Ratio is close to the limit imposed by EC3 The Design of the structure is not optimised Future Actions: A Technical Report and a Safety Study Report will be issued by TIS/TE-MC on the subject
