ABSTRACT:
A system for improving the horizontal fracture resistance of older chimneys and fireplaces comprised of units of brick, stone, and the like, in response to seismic, wind, and other external lateral forces, by placing the units under a vertical internal compression stress, increasing the shear capacity between the units, by means of a clamping action. Said clamping action is the results of providing one or more elongated members attached to an element affixed at the top of the chimney and an element affixed at a lower level, said elongated members being placed under predetermined tension creating a vertical internal compression stress.
