Abstract
In order to justify the feasibility of small-scale concrete masonry modeling technique for the construction of the 1/3-scale masonry test building, model masonry materials and assemblages performance related to nominal full-scale concrete masonry tests must be clearly established. This will be accomplished by conducting a suite of material tests (block units, mortar, grout, and reinforcing steel), assemblage tests (axial compression prism, bed-joint shear (cross specimens), diagonal tension, and flexural tension), and component tests (out-of-plane and in-plane walls) using both full-scale and reduced scale units. This experimental study is intended to investigate the feasibility of using of 1/3-scale direct modeling techniques of concrete block masonry materials and assemblages under different loading conditions. The methodology and techniques of fabrication 1/3-scale direct models of concrete block masonry components material and masonry assemblages were evaluated. For concrete masonry components material, the strength of block unit, mortar and grout and the stress-strain and ductility characteristics of reinforcement were examined. The behavior of ungrouted and grouted 1/3-scale assemblages were investigated by conducting axial compression, bed-joint shear, diagonal tension and modulus of rupture tests. Direct correlation between the model and prototype test results was performed. Good correlation of failure modes, strength and deformation characteristics was achieved. The experimental results demonstrated that direct modeling techniques applied to the investigation of behavior characteristics of masonry materials and assemblages is effective in understanding the overall behavior of full-scale concrete block masonry.
