    dynamic frequency assessment

    Ideem, here is the notes on the drawing, the operating frequency = 16.3Hz, I am reading this as the supporting structure is to be overtuned x2.5, however this is near impossible. As you pointed out, the structure is undertuned by 50% so it should be OK, however they are experiencing issues onsite.

    dynamic frequency assessment

    I have a structure supporting a vibrating screen, the vendor specifies the primary supporting members to have a natural frequency of 2.5 x operating frequency (16.3Hz), OVERTUNED - I am getting a natural frequency of the structure will all the dead masses = 8Hz. How does one overtune a...

    dynamic frequency assessment

    In determining the frequency modes for a structural frame supporting vibrating equipment, in addition to the equipment mass do we also include operating material load in the analysis? thanks in advance

    RC Wall Under Strength for Shear

    phamENG, the soil loading is out-of plane loading, its deficient in shear capacity due to lateral soil loading,

    Raft Slab on Rock Foundation

    I am designing a RAFT foundation for a RC vault. The raft measures 16m x 20m x 2m thick for the most part, the walls are 1m thick with the total design load(unfactored) 22MN. In checking punching shear, what are the parameters one should consider. Further is there a bending shear issue? Regards,
