APPENDIX A DESIGN TABLES In this Appendix a set of tables is provided for the design of rec- tangular slabs of given dimensions for different load intensities [w(1-C)] in the range 4 to 150 psf. For this purpose, designs for a total of five slabs are given as follows: 1. A small rectangular slab 24 by 40 ft. 2. A medium-size rectangular slab 30 by 50 ft. 3. A large-size rectangular slab 36 by 72 ft. 4. A large square slab 35 by 35 ft. 5. A medium-size square slab 30 by 30 ft. Each slab has been designed for three separate deflection condi lions, i.e., for allowable AL = 1/200, 1/300, 1/360. For each given load coefficient tw(1- C) ~ and allowable ratio (~/L), a number of slab designs are provided; they differ in number and/or width of stiffening beams and/or in depth of stiffening beams. In most cases of beams 8 inches wide, further increasing the width does not lead to a reduction in the reinforcement or the re- quired depth. In those cases for which an increase in beam width may permit use of shallower beams or less reinforcement, the tables so indicate by an alternative combination of dimensions with wider beams. In all cases, the designer is free to increase the beam requirements. In so doing it is not necessary to supply extra reinforcement, and it should not be concluded that compensation can be made by reduction in beam depth. 145

146 APPENDICES It is acknowledged that a designer will seldom be called on to design a slab with the exact dimensions and loads of those included in the tables of this Appendix, regardless of the large number of examples provided. The purpose of these tables is to permit a quick check of the design of a given slab by comparing its design characteristics with the slab in the tables which is closest in dimension and loading These tables will also prove useful in guiding the designer in the selection of trial beam layout and dimensions (b and d) of a slab to be designed, by reference to the closest slab for which a design is readily available in the tables. Finally, the tables in this Appendix could be used for an actual approximate design of a slab by interpolation, whenever the slab to be designed has the approximate configuration and dimensions of a slab for which a design is available in the tables. In preparing and organizing these tables, it was recognized that small effective slab loads tw(1-C)] will result either from small distributed loads (w) or because the coefficient 1- C is very small. However, if the latter is in the range 0.9 ~ 1- C ~ 1.0, the sequence of slab design is different from that required for the same w(1- C) effective load for which 1 - C ~ 0.9. Therefore, for values of wt 1 - C) in the range 4 to 36 psf, the tables provide slab designs for the different values of the support coefficient (1- C). Whenever the value of 1- C is not explicitly given in the tables, it is assumed that 1- C 2 0.9 and the slab design is thus independent of the exact value of 1- C depending only on the value of the effective load tw(1- C)] given in the first column of the ensuing tables. Example of Use of Tables Suppose it is desired to design a slab 30 by 50 feet in size, with a total average dead and live load of 340 psf, in a locality for which the support index (C) is equal to 0.75 and for a structure for which the allowable deflection ratio (~/L) is 1/300. Compute the load coefficient. w(1 - C) = 340~1.0- 0.75) = 85 psf Enter the appropriate table (p. 184) and in the first column with the value w(1 - C) = 85 psf (the value of w(1 - C) is designated in the tables as W).

APPENDIXES 147 There are a number of slabs available in the tables for different combinations of beam depth, width, and number. In the long direc- tion, the slab can be provided with 3 or 4 beams ranging in depth from 32 to 37 inches and in width from 8 to 12 inches (columns D, X and BX). All slabs have five beams, 8 inches wide along the short dimension (columns Y and BY). Assume that it has been decided to select the slab with 33-inch effective depth stiffening beams. Then, the D column of the table is entered at 33 inches, and the corresponding line of the table pro- vides all the design characteristics of the slab. Summarizing: 1. For a load coefficient w(1 - C) = 85 psf (column W), the depth of stiffening beams (d) is 33 inches (column D). 2. Use four (column X) stiffening beams 8 inches wide (column BX) in the long dimension of the slab at 30/~4-1) = 10-foot spacing. 3. Use five (column Y) stiffening beams 8 inches wide (column BY) in the short dimension of the slab at 50/~5-1) = 12.5-foot spacing. 4. The depth ratio (L/d) for this slab is 18.18 (column L/D). 5. The bottom steel ratio in the longitudinal beams is 1.15% (column PX). The bottom steel required per longitudinal beam is 3.05 in.2 (column AX). Four No. 8 bars with a cross-sectional area = 3.16 in.2 can be used per beam. 6. The additional top steel per longitudinal beam is also obtained from column AX by Subtracting 0.65 in.2 from the botton steel, i.e., 3.05 - 0.65 = 2.40 in. per beam. Three No. 9 bars with a total cross- sectional area = 3.00 in.2 can be used as top reinforcement per longitudinal beam, or one could accept 3 No. 8 bars = 2.37 in.2 7. The bottom steel ratio per short beam is equal to 0.75% (col- umn PY). The bottom steel per short beam corresponding to this steel ratio is 2.00 in.2 per beam (column AY). Two No. 9 bars will provide exactly 2.00 in., or if uniformity of bar diameter is de- sired, 3 No. 8 bars = 2.37 in.2. 8. The top steel per short beam is obtained from column AY by subtracting 0.65 in.2 from the bottom steel, i.e., 200 - 0.65 = 1.35 in.2. Two No. 8 bars will provide 1.58 in.2.

148 APPENDIXES 9. Since the squares of the surface slab have clear dimensions of less than 12 feet, i.e., 11 feet 8 inches by 9 feet 4 inches, a sur- face slab 4 inches thick, reinforced with No. 3 bars at 12 inches o.c. each way, will suffice. 10. Since the value of K is equal to 1 (column K), the steel design of this slab is controlled by bending moment. Had the value of K been equal to 2 (as is the case with some 32-inch-deep slab beams), design requirements would be controlled by the deflection criterion. 11. The last column (column N) provides the value of N. This is an index indicating whether or not reinforcement in the short direction of the beam is the minimum required or is determined on the basis of moment or deflection requirements. When N = 1, the steel in the short direction is required for bending moment. On the other hand, when N = 2, the short-direction reinforcement is equal to the minimum required, i.e., 0.3% of the effective concrete section of the beams. Note: These design tables were developed for A-15 reinforcing steel. If a higher strength steel (such as A-432) is to be used for reinforcing bars, the steel requirements provided by these tables can be modified in accordance with provisions in the text of this report.
