Hannes et al;

Iim wondering if your group has a copy of the 1996 Canadian tests (available 
from Canada Mortgage and Housing Corporation www.cmhc-schl.gc.ca ) done on 
pre-stressed,two-string bale wall panels ?

The pre-stressing process mentioned in the 1996 report utilises the plaster 
mesh as the tensioning element (intiially using automobile scissors jacks 
and later using a pneumatically-pressurised rubber tube to apply tension to 
the mesh and pressure to the straw) thereby enabling one to pre-compress the 
SB wall panel (hence achieving higher density bales) to anticipate any 
desired load levels.

I'm not sure that the compression test data for monster bales would be of 
any relevance since the stress levels on the straw would be much lower due 
to the increased bearing area of the large bales.

That being said, the compression resistance of the straw becomes moot since 
it is ultimately the plaster skins which take all of the gravity loads and 
for slender walls, so it becomes a matter of designing lateral load 
resistive systems to ensure stability.

G 'day All

I will be posting this to all the lists that I am on so remember the delete
key is your best friend.  The Straw Wolf needs your help to make this
happen.  It is straw bale, it is for a wonderful cause and it is very close
to my heart, so no apologies for content or for cross posting.

It has been a while since I last wrote to you about Mama Amelia.  I have not
forgotten her and never will!  I just had to find some space to devote to
the strawphanage, that's all.

I now have some breathing space and will put aside time each day towards the
goal of building the strawphanage for Mama Amelia.

So if you are still interested and can offer some help, advice, design,
physical help, contacts, fund raising and moral support, stay tuned.  If you
want to be deleted from this list of "the Friends of Mama Amelia" please
advise by return email, and I will delete you from the list.

The Yahoo group for Mama Amelia is open and if you want to join that to make
the discussions easier then I will send you an invite to join that list.

So to work;  just briefly I have extended the closing date for the design
competition to the 31st August 2003.

Mama Amelia's web site:


The problem of abandoned children in Capetown has not gone away and nor have

Please advise all designers and architects that you know that we need a good
LOW cost design for the strawphanage.

The video will be available on loan to anyone who needs a copy by the end of
next week.  I have 10 copies being made so we will have to share around.

If you receive a duplicate of this email please let me know which address
you prefer to be notified on.  Also if you think that someone you know
should be notified send me their address, with their permission of course.

Time to get Fair Dinkum about this, Mama Amelia needs shelter for her

Kind regards
The Straw Wolf
