D13.A.2 Design Parameters
Entry of data of cross-sections of beams and columns is made by the use of MEMBER PROPERTIES command, and thicknesses of 2D members are entered by ELEMENT PROPERTY command.
Example:
UNIT MM MEMBER PROPERTIES * Columns of rectangular cross-section 1 TO 16 PRI YD 350. ZD 350. * Columns of circular cross-section 17 TO 22 PRI YD 350. * Beams of T cross-section 23 TO 40 PRI YD 450. ZD 550. YB 230. ZB 200. UNIT METER ELEMENT PROPERTY 41 TO 100 THICKNESS 0.14 101 TO 252 THICKNESS 0.16 * Flange of T beams is located at the bottom zone of cross-section BETA 180. MEMB 23 TO 40
Commands for calculation of reinforcement are located in the input data file after the command of analysis and as a rule, after output commands to print results of calculation.
Example:
* Command of analysis PERFORM ANALYSIS . .* Output command to print results of calculation (according to user’s judgment) . * Command of loading and their combinations considered in design LOAD LIST 1 5 TO 9 * Command to start reinforcement calculation procedure START CONCRETE DESIGN CODE RUSSIAN .* List of parameters being used in reinforcement calculation . . BCL 20. MEMB 17 TO 22 CL1 0.04 MEMB 1 TO 40 DD2 10. MEMB 23 TO 40 CRA 0.036 MEMB 41 TO 252 . . . * Command of beam reinforcement calculation DESIGN BEAM 23 TO 40 * Command of column reinforcement calculation DESIGN COLUMN 1 TO 22 * Command of calculation 2D elements (slabs, walls, shells) DESIGN ELEMENT 41 TO 252 * Command of interruption reinforcement calculation END CONCRETE DESIGN
In tables 1, 2 and 3 information about parameters used for calculation of reinforcement for beams, columns and 2D (two dimensional) members is presented. Values of parameters do not depend on UNIT command. In the file of input data only such parameters have to be taken, the values of which differ from determined in the program.
