Towards Developing a Flexural Strength Design Methodology for Concrete Masonry

Source

In order to develop an appropriate flexural strength design methodology for concrete masonry, information about the nonlinear stress distribution in the compression zone is needed. This paper presents experimental results from grouted concrete masonry prisms tested under eccentric compression loading in the out-of-plane direction which is part of Task 1.2 (a) of the U.S.-Japan Coordinated Program on Masonry Building Research. The stress parameters k1k3 and k2 are presented for 150 mm (6 in.) concrete masonry and are used to predict the ultimate moment capacity of full-scale reinforced masonry walls. Good agreement was obtained between the predicted and the experimental moment capacities. An equivalent rectangular stress block is presented. It is concluded that a design methodology similar to that for reinforced concrete is feasible for grouted concrete masonry.
