<p>Diagonal compression tests of masonry walls made of interlocking brocks with various shapes were conducted. I-shaped brocks with right angle, I-shaped brocks with obtuse angle, hourglass-shaped brocks with straight edge, and hourglass-shaped brocks with wavy edge were compared. It was found that the masonry walls made of hourglass-shaped brocks have larger strength and those made of I-shaped brocks have less. The finite element analysis was conducted to understand the mechanism. It was found that the walls with I-shaped brocks have less strength due to stress concentration at the interlocking part. It was also found that the walls with hourglass-shaped brocks have larger strength but larger displacement due to dislocation and rotation of brocks.</p>
