This Table provides a conservative estimate of f based on the mortar and concrete block unit compressive In ACI the factor of 0. ECE to Drexel University is gratefully acknowledged.

Therefore, the code minimum steel requirement in the horizontal direction 0. This wide range is attributed to variation in. Citations are based on reference standards. Walls with joint reinforcement in every course had a more developed crack pattern than walf with joint reinforcement in just every other course. In comparing the ultimate load with the cracking load, it is found that joint reinforcement in every course increased the flexural strength by to percent depending on the type of reinforcement standard or extra heavy and joint reinforcement in every other course increased the flexural strength by just 64 percent Table 3.

The panel size was 32 in. The average compressive strength of the acii was psi. The typical panel was made up of three full courses in addition to a half course at the bottom and at the top see Figure 1to represent a typical wall strip cut from center-of-block to center-of-block.

A loud snapping noise was heard shortly after the ultimate load was reached in the wall panels indicating the rupture of the joint reinforcement. Once the crack pattern in the pure moment region had been established, load redistribution in acl wall panel occurredas evidenced by the appearance of a set of vertical cracks just beyond the pure moment region. Figure 2 shows a schematic of the experimental set-up.

Flexural Strength of Joint Reinforced Block Masonry Walls

This Table provides a conservative estimate of f based on the mortar and concrete block unit compressive In ACI the factor of 0. The complexity of the crack pattern was found to be dependent on the spacing of the joint reinforcement.

The cylinders were air-cured alongside the companion walls 53179 tested under axial compression at approximately the same age as the walls.
