Hi
I hope this is the right forum for this post??
We are looking at designing a secondary containment bund for an oil storage facility using R.C panels. The site is in a seismic area and therefore it is considered prudent to check a design scenario that the bund is full during a quake (eg...
Hi All
API 650 Appd E gives a table of response modification factors (for ASD methods) for use in calculating the spectral acceleration parameter.
These factors account for a combination of affects including ductility, damping, overstrenth and presumably to account for the fact that ASD method...
Hi All
Have posted this in "storage tank" forum as well
I am designing a 36m tank where the client requires a column supported roof. I am doing the preliminary layout for the roof members and wondered whether there were any industry rules of thumb for layouts that lead to efficient designs...

We are often asked to design industrial portal frame buildings for use as loading facilities for trucks etc. Typically these are long rectangular single story buildings with gable roofs or similar. They are fully clad along the side walls and roof but fully open at both ends to allow the...
Hi all
I have a tank structure (with four legs) that needs to be anchored to an existing concrete slab. The chemically fixed anchors I want to use require a min embedment depth of 300mm. I can only get 200mm embedment out of the existing slab.
I can pour local footings/plinths on top of the...
Hi
We have been asked to design a truck wheel wash facility.As part of this the client has requested that a SFRC slab be used.I have experience is in designing conventional RC slabs on grade but not SFRC. The design procedures I can find seem reasonably complex and it appears that these are...
Hi
I have been using a response spectrum solver on a particular problem for seismic base acceleration analysis. While I am satisfied that the model is giving me the correct structural displacements and hence member loads I am curious as to the solver output text.
For each mode of vibration the...
