GSBN:Seismic performance of sb

[bainbridge bainbrid@...]

Seismic performance - just a quick note

The earthquake engineering group at the University of California San 
Diego is testing concrete walls with free reinforcing (tension rods 
inside sleeves rather than in concrete). This acts like a tendon to 
return the walls to vertical after swaying and looks very good in 
early tests.

Interesting as it may act like reinforcing in a sb wall in some of 
our earlier systems with threaded rod or ties running through the 
bale instead of through the plaster or stucco. For external 
reinforcing we may get the same effect if the ties are placed under a 
plastic or wood cover so they are decoupled from the plaster.

So much to learn....

Cheers
