ABSTRACT

The paper deals with the verification of a new design approach for shear stressed masonry structures. Therefore the results of pseudo-dynamic test on large-scale unreinforced masonry terraced houses have been compared with the respective results of the new approach and the already existing approach of DIN 1053. Both, the large-scale test and the development of the new design approach were part of the European research project ESECMaSE (Enhanced Safety and Efficient Construction of Masonry Structures in Europe).

On basis of the comparison, the deficits of the traditional way of designing shear stressed masonry walls have been discussed. It could be shown that the results of the new approach matches very good with the test results, if one considers a realistic structural system. The commonly used cantilever as structural system for unreinforced masonry shear walls does not seem to be appropriate. This applies for the new design approach as well as for the already existing approach of DIN 1053.
