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:
​
-
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;
-
- 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;​
- 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.
