Abstract:
Failure modes of monotonically loaded Grade 60 deformed tension bar anchorages in grouted concrete masonry walls are described. Assuming uniform nominal bond stress, mathematical models are developed for each failure mode using elasticity and finite element techniques. Nominal bond strength is predicted using compressive strengths of masonry constituents. Predicted anchorage capacities and failure modes agree well with test results.

Two hundred and twenty block masonry prisms were tested under eccentric compressive loads having eccentricity to thickness ratios of 0, 1/6, 1/3, and 5/12. The influences of grouting, percent solid, block size, and block strength for different eccentricities were studied. The results show that the strengths of the block and grout do not have a significant effect on the relative decrease of capacity with increasing eccentricity. The percent solid has considerable effect on the relative capacities for ungrouted prisms. For ungrouted prisms the increase in extreme fiber ultimate compressive stress with increased eccentricity was small, indicating no effect on the strain gradient for hollow blocks. For solid and grouted prisms there was a significant increase in extreme fiber ultimate compressive stress with increased eccentricity (increased strain gradient).

Presents data on the load carrying abiiit of concrete masonry walls made with units of wide varying l characteristics, both during and after exposure to standard fire test conditions. Comparative data on similar walls not exposed to fire are included. The in- vestigation comprised tests on more than 200 walls 5 1/2 ft wide, 6 ft hi h, and 4, 8, and 12 in. thick. An outstanding eature of the investigation was the f substantial toad-carrying ability and safety exhibited by the walls before, during and after severe fire ex-posu re.
