A bstract Ceramic masonry units, properly formed of suitable raw materials and well fired, are characterized by high compressive strengths. When assembled into building members their usefulness ordinarily is limited by the weakness of mortar joints; even the inclusion of reinforcing in a mortar joint fails to develop the potentialities of the high compressive strengths and stiffness available in the units. Prestressing does, in effect, change part of the excess compressive strength into tensile strength, permitting much better application of materials, whether in beams or in columns. In the former, the underside is placed initially under compression while, even in columns, suitable prestressing reduces the buckling tendency of slender members which otherwise would cause failure far short of the compressive‐strength potentialities. Analysis of the prestressing and loading operations is secured with the aid of celluloid models and polarized light.
