NZS1170.5 Parts & Components Query

[moyseh]

Hi All,

I have a situation where I'm treating a lighter structure on top of a much heavier structure as a Part for seismic loading.

My question is what I ought to consider as the height of the attachment of the part (hi) when determining CHi?

I understand that for precast panels for example, you actually have a trapezoidal load distribution as the seismic load increases as you go up the panel. I just can't see how I should treat it for my case?

Thanks,

The base of the lighter storey or component. Basically the point at which the structure imparts the accelerations on the part.

Thanks guys - appreciated

By the way the reason why you might consider a trapezoidal load on a panel is simply because it effectively has two points of attachment, so in effect the top of the panel gets a different applied acceleration to the bottom of the panel, hence the trapazoidal approach.
