You will find above the different exercises of the second stage, the input data to download and the results required

​Stage 2:

  • Exercise 8 -   RUN 80 seismic 1.5g -   Centered configuration -     Mixed wheels

  • Exercise 9 -   RUN 42 seismic 1.5g -   Centered configuration -     Sliding wheels

  • Exercise 10 - RUN 112 seismic 1.5g - Decentered configuration - Sliding wheels

  • Exercise 11 - RUN 128 seismic 1.5g - Decentered configuration - Mixed wheels

  • Exercise 12 - RUN 100 seismic 1.0g - Centered configuration -     Mixed wheels

After the calibration of the models in Stage 1 (exercises 1 to 7), prediction exercises are planned in Stage 2.

It aims at evaluating the nonlinear response of the crane bridge mock up under high intensity seismic loadings.

The results of the experimental RUNs are not provided in these exercises. Only seismic signals at the table level are communicated for use as input data for the simulation.

Stage 2 - Blind simulations

2-directionnal and 3-directionnal input signals (seismic excitation) for the 5 exercises of Stage 2, are available here.

Participants are invited to perform the following tasks:

  1. provide acceleration time evolutions at different points:

    • on the trolley; at points AxChariot1, AyChariot1, AzChariot1;

    • on the girder beam; at points AxPcharge1H1, AyPcharge1H1, AzPcharge1H1;

    • on the runway beam; at points AxProule1H3, AyProule1H3, AzProule1H3;
       

  2. provide displacement time evolutions of different points:
    • of the trolley, in direction X: DxChariotA-B-C-D;
    • of the end-truck beams, in direction Y: DySomA-B-C-D;
    • of the girder beams, in direction Z: DzPcharge1-2;​
       
  3. provide force time evolutions at supports: ​
    • in the 4 load cells of each load cell block (A, B, C, D). 

See page Member>Instrumentation to get details on the positions of these points.
