Not illustrated. 1905 edition. Excerpt: ... the materials. This would include the range of strength that the given material has in tension, compression, transverse bending and shear, the modulus of elasticity, the modulus of resilience, the elastic limit, the coefficient of expansion, the size of test pieces that the above values are based upon, the percentage of moisture of timber, and its influence on its strength, the quality of the material, and the influence of probable defects such as knots and season checks in timber, blowholes in castings, probable inequalities in cement and steel and deterioration of stone clue to influences of the weather, and other seen and unseen defects that are likely to occur. To this must be added the consideration of the liability of timber to rot, and of steel and iron to corrode as well as the influences of intense heat or cold if probable. The third item that enters into the make up of the factor of safety is the nature of the structure, whether temporary or permanent, important or unimportant, and the possible damage that may be caused by failure, and whether or not such failure may ocv cur with or without warning. The stiffness or rigidity of the structure should also be considered as an element equally important as that of the strength. Arrangements should be made that certain limits of deflection are not exceeded, and it should be seen that such deflections do not produce secondary stresses difficult to compute, and also that the lateral stiffness of joists, beams, girders and columns is properly looked after. Scantness in the size of joists and timbers and probable imperfections in workmanship are often loaded on the factor of safety. For special constructions as, for example, long span segmental hollow tile arches, it should be...
