In the following pages are given a large number of test questions and problems which afford a valuable means of testing the reader's knowledge of the subjects treated.
Page 200 - In the case of columns this can be done on a standard size sheet, generally 12 X 30 in. or 18 X 30 in. Girder sheets and truss sheets generally vary in size with the particular conditions of each case. The first operation necessary is to draw out the outlines of the member to be detailed, showing a side elevation and plan, or end view and sections where necessary to clearly show all the work to be done.

The factor of safety should be from 2 to 12, varying with the accuracy of the knowledge of the loads to be carried and with the closeness with which the formulae used fits the conditions of the special case. Fig. 152 shows a footing supported by piles. Fundamental Principles. The...
Page 195 - All segments of compression members, connected by latticing only, shall have tie plates placed as near the ends as practicable. They shall have a length of not less than the greatest depth or width of the member, and a thickness not less than one-fiftieth of the distance between the rivets connecting them to the compression members ".
