In the July, 1930, issue of Brick andClay Record appeared an article byDr. Kanamori, civil engineer in a de-partment of the Imperial JapaneseGovernment entitled, ReinforcedBrickwork Opens Greater Possibili-ties. In it is shown photos of heavy retaining walls of reinforced brick-Comparing the result of tests andthis formula we arrive at a factor ofsafety of 3 to 5 from which I can saythat if reinforced brickwork would bedesigned by this formula no dangerneed be expected. I have built manystructures such as buildings, retain-ing walls, quay walls, bridge piers,abutments, and so forth, where myconstruction practices have bLe;i em-ployed. There is no question that the rein-forced brickwork should be used in-stead of brickwork when any tensilestress would be occurred in Top of brick bearing wall building, Los Angeles, showing reinforcing barsembedded directly in brickwork. Note wall anchors work used in conjunction with somelarge canals and quays, the walls ap-pearing to be 20 to 30 feet high. Without discussing the technicalphases of this work it may be statedthat it is entirely successful. Onequotation, however, may be of inter-est. ... I will state that the natureof r«nforced brickwork is like rein-foiced concrete and the formula forbuilding reinforced concrete may beused in designing reinforced brick-work except introducing 25 for n (theratio of modulus of elasticity) whichis 15 for reinforced concrete. Belowis given a practical formula for de-termining the dimensions of rein-forced brickwork: We can make them more safe andstronger, saving much cost. Further, I have found that rein-forced brickwork is more convenientand economical in building than rein-forced concrete and what is still more bh= = • Be • M, a
