    Boundary condition

    Boundary condition describing wheels is applied to the model as presented in following

    figures. U=0 means the displacement is not constrained, U=1 means the constrained.

    6. Loading condition

    Three load cases are created and analyzed

    Dead Load (self-weight) (DL): the weight of structure calculated internally in the software.

    Live Load 1 (LL1): Describe one worker with tools and equipment stand at center of thedeck. The load is concentrate force of magnitude of 1kN.

    Live Load 2 (LL2): Two people standing on outer half of the chair. The load is uniform load

    on half of the deck area with magnitude of 5.0KN/m2. Total load on the deck will be 5.0 x0.4 x 1 = 2kN. The applied load is shown in following Figures.

    Comments and Conclusions

    - The structure of the case will work in safety if the design of structure and member

    section follows the above input and analysis data.

    - Designer is requested to revise the drawing in accordance with this analysis report.
