ABSTRACT
The initial shear strength of old masonry is similar to the strength of laboratory made masonry and the coefficient of friction is almost equal. Different parameters are required for accurate design, analysis and simulation of the behavior of masonry structures. To investigate the mechanical properties of the various types of the original masonry and its constituent materials, experiments were performed, both in situ and in laboratories, Nederlandse Aardolie Maatschappij. Masonry specimens arrived in the laboratory at Eindhoven University of Technology, packed in wood to prevent transport damage. The CUR tests also resulted in a relationship between elasticity modulus and strength. The compression tests of the CUR-project showed that the shape of the stress-strain diagram could be schematized by a second degree parabola. In the CUR project, J. G. Rots a parabola was used to describe the stress-strain relationship.
