Abstract

Dynamic criteria for the reinforcement of old buildings B. Leftheris, E. Tzanaki, M. Stavroulaki Applied Mechanics Laboratory, Technical University of Crete, Chania, Crete, Greece ABSTRACT The influence of reinforcement methods in the structural life of masonry walls during the restoration of old buildings is the subject of this work. Comparison of the stress distributions due to earthquake loadings before and after reinforcements using the method of finite elements, permits us to find the critical areas of overloading and to determine the effectiveness of the reinforcements. The prestressed cable method of reinforcement is shown in some detail. Given the materials and geometry of an old building, our main purpose is to improve the prestressed cable method so that the structural wall can have a longer life under consecutive dynamic loadings. INTRODUCTION There is an increasing interest in the study of maintenance of masonry walls of historical
