Page 159 - For square arches the concrete shall be laid in transverse sections of the full width of the arch, between timber forms normal to the center line of the arch, the length of sections being such that the center section, or a pair of intermediate or end sections, shall constitute a day's work.

Page 79 - Fig. 21, and the portion of the truss to the left of this section is removed.

Page 157 - The horizontal thrust from dead load and maximum tempera201 86 ture is 213.94+2.96 = 216.90 tons, and ":"X46.4 ft. = 43.2 ft., _ i o.yu which is the ordinate of the point of intersection of the line of pressure on the panel line I.

Page 242 - ... the neutral axis passes through the center of gravity of the section when unit stresses do not exceed the elastic limit of the material.

Page 44 - This is true when these forces are all located on the right side or on the left side of the axis of symmetry, which in this case is a vertical line passing through the point h.

Page 203 - Also the bending moment is equal to the moment of resistance of the concrete in compression and the reinforcement in tension.

Page 264 - F = (ZF) cos a - (Ztf) sin a (14) vhere a is the angle which the tangent to the arch axis makes with the horizontal. Having given the internal forces acting on any section, the fiber stresses can be determined...
