[Strawbale] permissible load on load-bearing strawbale

[Derek Stearns Roff]

If I remember correctly, there is a discussion of seismic design issues in Design of Strawbale Buildings: The State of the Art.  Also take a look at the PAKSBAB site, and their research links, which include some seismic testing (shake table).  http://www.paksbab.org/html/index.php?id=1

Thank you Derek for the useful links.
They are answering lot of questions.

If there is also some information from seismic point of view will be very helpful. The building site is located in seismically active region- zone of the 9 by Richter scale.
Here the forces are very specific by themselves with horizontal and vertical directions with big amplitudes and long duration.

Thank you all guys for your help!
That means a lot for me and our community here in Bulgaria !

The testing has shown that plastered strawbales can take tremendous loads.  Links or summaries of some of those tests are posted on the Ecological Building Network website.  http://www.ecobuildnetwork.org<http://www.ecobuildnetwork.org/>  They are trying to build a useful, natural building library.  Check it out, and contribute to it.

The testing is on this page:  http://www.ecobuildnetwork.org/library/building-materials/fibers/straw/strawbale

On that page, you will also find a link to free PDF downloads of Bruce King (and others) outstanding reference, Design of Strawbale Buildings: The State of the Art.  It’s a great book for understanding many aspects of building.

Hi everyone,
can I ask does anyone knows what is the allowable load for clay or lime plastered Load-bearing Strawbale walls ?

The project will take place in Bulgaria, near Shabla, still we do not have building codes for Load-bearing, so any advice from seismic active regions will be very welcome. This building is planed to be experimental educational center for sustainable development and for us this is part of a great mission and challenge.

According to the calculations of the engineer the expected load from the green roof to the strawbale wall will be 1720 kg/m /kilograms per linear meter/ or 16,867 kN/m.

I am attaching some drawings to make it more clear.

This kind of buildings are still not legal according to our building codes /except the one build from Barbara Jons in Hotnica/, so we want to design it properly as it should be. We want it to be correct according our own personal and community building and moral codes.
With your help one day it will be all.

Thank you in advance for your help.

Best regards
Nikolay Marinov, architect
