What reading level is Civil Engineering Specifications And Contracts book?
To quickly assess the difficulty of the text, read a short excerpt:
In case the sum of the stresses per square inch in the chords and end posts of truss bridges, or the posts of trestle towers due to the live load including impact, the dead load, and the wind shall exceed 19, 000 pounds per square inch properly reduced for compression, the section shall be increased until this limit is not exceeded.
In the end posts of through bridges the sum of these stresses added to the maximum fiber bending stress per square inch, pro- duced by the portal bracing, shall not... exceed 20, 000 pounds.
Should the stresses be reversed in any case, proper provision shall be made for such stresses.
Portals and Diagonal Bracing. All through spans with top lateral bracing shall have riveted portal bracing composed of angles, latticed as deep as the headroom will allow, rigidly con- nected to the end posts.
When the height of the truss exceeds 25 feet, an approved system of overhead diagonal bracing shall be provided at each panel point.
Deck bridges shall have diagonal bracing at each panel point proportioned to resist the unequal loading of the trusses; the position of the track, and the action of the wind and the cen- trifugal force being considered.
