BAIXA POMBALINO WALLS
Rua Dos Sapateiros, 39
Baixa

Lisboa, Portugal

Photographs Randolph Langenbach, January 27, 2003 *

 

  

STEREO PAIR:  This view can be seen in 3D using the eyes crossed method.*

*To view it in 3D without the aid of a viewer, cross your eyes until the two images merge to form a third image in the middle.  That middle image will be in 3D.  It can sometimes help if you take two identical pencils, and hold the eraser ends under the middle of each image.  Then cross your eyes until the two erasers overlap, and the image above then should pop into 3D.

NOTE:  The two thumbnails on the "Gaiola" Page are placed so as to form a 3D image using the eyes-parallel method.


The two images below are taken of the test walls photographed at the University engineering lab after completion of the lateral force testing which has loosened the infill masonry. By seeing them in 3D, the position and configuration of the infill masony can be discerned. The infill commonly extended beyond the surface of the diagonal timbers as seen here.
