    Braking force

    Hello, I am evaluating an elevator tower. The tower mast shows displacements not contemplated and produces premature wear in the pieces, so they asked me to calculate the structure, I already have almost all the loads according to the corresponding standards and I still need to calculate the...

    Forces from elevator to tower structure

    Thanks desertfox, Now the issue is, I need to introduce those loads in sap2000 without drawing the elevator, that is, only the tower that supports it and the loads. Do you have an idea of ​​what charges to enter? I was thinking of entering the torques but as I represent the reaction forces of...

    Arch frame formulations and SAP2000

    Hello, Right now I do not have sap2000, I wanted to verify that arch frame with the measures that I indicate to optimize the structure in the software, however due to the inconsistency in the reactions I am using only excel.

    Arch frame formulations and SAP2000

    Hello everybody, I checked the calculations and apparently everything is fine. At this stage I still do not go to see the section of the profile, which if I tried that the columns and the arch are of the same section. I have not moved the modifiers.
