Author AHMAD SABHA TV Dresden Abstract The proof of structural safety for historic masonry buildings and the evaluation of their bearing capacity according to current codes leads often to underestimation of their actual existing strength. In order to avoid this...

Author JAN KUBICA Silesian University of Technology, Gliwice, Poland Abstract The problems of analysis of stiffening walls of buildings are connected with shearing in the horizontal and vertical directions. Protection of buildings against vertical shear loads is still...

Author MARIA GORET MARGALHA Beja City Hall Abstract Portuguese historic buildings were mainly built using lime mortars, not only as renders, but also as bonding material, together with stone and bricks. Preserving this heritage requires, as in other countries,...
