PREFACE THE purpose of this book has been to eliminate as far as possible the eae drawing or figuring consequent upon the design of Pitched Roof russes. The most economical forms have been taken from the labyrinth of styles which are more or less in use. Sufficient data has been given to enable any person at all versed in struc- tural work to design trusses within the ranges of pitch, span, center to center of trusses, or loads covered by this work, which are the minimum and maxi- mum usually adopted in practice by skilled engineers. The tables of stresses are figured on the assumption that loads are con- centrated at panel points only. Any additional stresses, due to bending or unsymmetrical loading, must be added to the stresses given in these tables. The trusses must be built symmetrically. Great care has been taken in checking all figures in this book and they may be relied upon as correct. For the purpose of greater accuracy the stresses have been given to the last figure, but in practice, if the figures are given to the nearest hundred pounds, they will be close enough. The following information in reference to the headings of the columns in the tables may be of assistance to the student. The first column is headed “CtoC. Truss’s ft.” This is the abbreviation of Distance Center to Center of Trusses in Feet. The second column is headed “Total Load on Truss.” The figures given in this column are equal to Span X Distance Center to Center of Trusses X Load per Square Foot. The letters at the head of all the other columns refer to members of the truss, and correspond with the letters shown on the line diagrams preceding each set of tables. Examples of the manner in which stresses for various trusses may be found, are given on pages 2, 34, and 66. The tables of Compression and Tension Members have been made as comprehensive as possible, and may be used for all forms of structural work, and need not be confined to use in designing trusses. Extracts from Building Laws of various cities are given as a handy refer- ence in matters pertaining principally to structural work. The publishers and the author will appreciate any suggestions tending to make future editions of this book more valuable, and in cases of typo- graphical errors it will be considered a favor if attention is brought to the same.

Stresses for this type of Truss are given on pages 3 to 32 TABLE SHOWING CoMPRESSION AND TENSION MEMBERS Compression Members Tension Members AC CF BD EF CD DE EF 2 The following examples will show the method of procedure in finding the stresses for trusses of the type shown '‘above:: . Examp_e 1 Required the stresses in a truss of the above type with a span of 27 ft., distance center to center of trusses to be 15 ft., load of 40 lbs. per square foot, pitch equal to } of span. Referring to page 5, the stresses in each of the various members of the truss are given as follows: Total Load on Truss AC | BD cD DE CF EF 16,200 lbs. 13,576 | 11,761 3645 4050 12,150 8100 Although the spans and distances center to center are given for differences of 1 ft. and the loads per square foot vary by tens of pounds, it is possible to find almost exact figures for any span, center or load where fractions are introduced, as will be illustrated by the following case: EXAMPLE 2 Assume a span of 29’-7}”, distance center to center of trusses 11’-2}”, load of 37 lbs. per square foot, 30° pitch. e In all similar cases (where there are fractions of feet in span or centers, and loads other than 30, 40, 50, 60 or 70 lbs. per square foot) the total load on the truss must be figured. For this case 29’-7}” < 11’-2}” x 37 Ibs. = 12,308 lbs. Having found this load, look down the column headed ‘Total Load on Truss”’ until a load equal or close to the one sought is found, which in this case is on page 16 under 28 ft. Span c. to c., Trusses 11 ft., and load of 40 Ibs. per square foot. Having found this figure (which is 12,320 lbs. or 12 lhs. more than the figure looked for —the difference is too small to make any difference in the stresses), the stresses are as follows: Total Load on Truss AC | BD CD & DE CF EF 12,320 Ibs. 9240 7700 2669 8008 5338 20-ft.

Asin Example 2, page 2, the total load on truss must be found. In this case 37’-5” x 14’-10” < 42 Ibs. = 23,310 lbs. Looking through column headed “Total Load on Truss,” a similar number is found on page 38 (under 39 ft. Span, ¢. to c., Trusses 15 ft., load 40 lbs. per square foot), which is 23,400 lbs. or 90 lbs. greater than the required amount. This difference is such a small percentage of the total load that it may be neglected and the stresses written down thus: Total Load on Truss AD BE CF DE & EF DH GH | FG 23,400 Ibs. 21,762 | 17,714 | 18,322 4212 19,492 | 11,700 | 7800 34 30-ft.

Figures are given in the cases of two angles with the axis placed in two different directions, and, for angles of unequal legs, with the long and short legs outstanding, which makes the tables complete for all purposes. EXAMPLE Required the size of two angles to support a compressive load of 48,000 lbs., the un- supported length of the member to be 10 feet. Referring to page 180, and looking down the column headed 10, which is the length, the figure 480 will be found, and since the loads given are in hundreds of pounds this is the figure sought. Following the line, where this 480 occurs, to the left, to the column headed “‘Size of Angle,” the size required is given as 4 X 3 X 3. 174 COMPRESSION MEMBERS Recess 1 Angle (Equal Legs) Tenet aided by =Length in Inches east Radius of R= Radius of Gyraton New York Gyration not to 15200 ~ 58 e exceed 120 Aals a6 indicated vy dotted line, ‘S 3 “ aa = Length in Feet — Total Allowable Loads in Hundreds of Pounds i Se al g Ss a 3 - g I 2 3 4 5 6 8 Size of Angle ‘ 2 cet pea lida 12X13 x #; | 0.35 | 0.62 82 70 57 45 13k14x 4 | 0.34/0.81] 107 90 73 57 131} xz | 0.34!

of compression members contained in the following pages, 188 to 198, are 16,000 based on the formula 1_ L? and are given for one and two angle sections. The 1+ 30,000 R® lengths are carried to the nearest foot when the length divided by the radius of gyration is equal to or less than 130. _ Figures are given in the cases of two angles with the axis placed in two different direc- tions, and for angles of unequal legs with the long or short legs outstanding, which makes the tables complete for all purposes or arrangements. EXAMPLE Required the size of two angles to support a compressive load of 48,000 lbs., the un- supported Jength of the members to be 10 feet. Referring to page 192, and looking down the column headed 10, which is the length, we find that the nearest numbers to 48,000 are 48,400 and 47,600; since 48,400 gives a little higher value than required, this will be decided upon. Following the line, where this 484 occurs, to the left to the column headed “Size of Angles,’’ the size of two angles required is given as 34 X 24 X 45. 187 L =Length in Inches R=Radius of Gyration COMPRESSION MEMBERS 1 Angle (Equal Legs) Chicago or Boston 16000 1 L i= * 30000 R?

The strengths of these angles are figured for unit stresses from 7000 to 20,000 lbs. per square inch; varying by 1000 lbs. EXAMPLE Given a tensile stress of 80,000 Ibs., find the size of two angles strong enough to with- stand this stress, making allowance for two }” diameter holes which will be taken out of each angle; the fibre stress not to exceed 16,000 lbs. per square inch. Referring to page 207, and looking down the column headed “16,000 pounds per square inch,” the number 400 will be found; then following along this line to the left, to where the column headed “Size of Angle’’ is given, and there the size of the angle will be found to be 34 X 34 X 4. In these tables the total loads are given in hundreds of pounds, therefore 400 in the tables is equal to 40,000 Ibs., and since the figures in the tables are given for one angle, this 40,000 must be multiplied by 2, then the figures will be equal to 80,000 Ibs. for two angles. 200 TENSION MEMBERS One Angle (Equal Legs) .
