Abstract:
A better understanding of the complex behavior of masonry structures is necessary to embrace the more appropriate concept of limit state design. Due to the prohibitive cost of full-scale testing of masonry systems, particularly under dynamic loading, a more economical method utilizing a direct modeling technique is proposed. This paper presents an historical perspective of the use of small-scale models for brick and block masonry, focusing on small-scale block masonry research that has been conducted at Drexel University over the last 14 years. Developments of model masonry materials, such as units, mortar, grout, and reinforcement are presented. Correlations between model and prototype results in basic strength characteristics are reported. This includes axial compression, joint shear, and splitting tension. Applications of the use of small-scale models in floor-wall connections and slender reinforced masonry walls are described. It is concluded that direct modeling is feasible and is capable of predicting the behavior of concrete block masonry.
