overhung load under seismic

overhung load under seismic

overhung load under seismic

under seismic conditions, how can we calculate loads on structure caused by an overhung weight (i.e. load lifted by a crane) ? We assume the crane fixed with the structure so that the suspension point of the lifted load is moving because of seism, adding load to the structure

RE: overhung load under seismic

Depending on what you want to check - the support structure, or the crane. Just be conservative.

RE: overhung load under seismic

I would like to calculate the load transferred to the structure from the waving hung-load

RE: overhung load under seismic

Never had to design of it, but Google is pretty handy...


RE: overhung load under seismic

Then, the worst case would be treating the lift weight as an added mass of the crane. It would lower the mass center of the crane.

Thks phamENG, exactly what I was looking for
