    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...

    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,
