EX. US-23 Spring Support Generation for a Slab on Grade

This example illustrates the usage of commands necessary to automatically generate spring supports for a slab on grade. The slab is subjected to pressure loading and analysis of the structure is performed.

This problem is installed with the program by default to C:\Users\Public\Public Documents\STAAD.Pro CONNECT Edition\Samples\Sample Models\US\US-23 Spring Support Generation for a Slab on Grade.STD when you install the program.

Example Problem No. 23

where:
  • H = 129', h1 = 8'-6", h2 = 8', h3 = 6'
  • V = 40', v1 = 6'-6", v2 = 6', v3 = 7'-10", v4 = 4'
    STAAD SPACE SLAB ON GRADE

Every STAAD input file has to begin with the word STAAD. The word SPACE signifies that the structure is a space frame and the geometry is defined through X, Y, and Z axes. The remainder of the words form a title to identify this project.

For joints 1 through 7, the joint number followed by the X, Y, and Z coordinates are specified above. The coordinates of these joints is used as a basis for generating 21 more joints by incrementing the X coordinate of each of these seven joints by 8.5 feet, three times REPEAT commands are used to generate the remaining joints of the structure. The results of the generation may be visually verified using the STAAD graphical viewing facilities.

    ELEMENT INCIDENCES

    REPEAT 16 6 7

The incidences of element number 1 is defined and that data is used as a basis for generating the 2nd through the 6th element. The incidence pattern of the first six elements is then used to generate the incidences of 96 (= 16 x 6) more elements using the REPEAT command.

    SUPPORTS
    1 TO 126 ELASTIC MAT DIRECTION Y SUB 10.0

The above command is used to instruct STAAD to generate supports with springs which are effective in the global Y direction. These springs are located at nodes 1 to 126. The subgrade modulus of the soil is specified as 10 kip/cu.ft. The program will determine the area under the influence of each joint and multiply the influence area by the subgrade reaction to arrive at the spring stiffness for the FY degree of freedom at the joint. See TR.27.3 Automatic Spring Support Generator for Foundations .

    PRINT SUPP INFO

This command will enable us to obtain the details of the support conditions which were generated using the earlier commands.

Load case 2 consists of several joint loads acting in the negative global Y direction.

    LOADING COMBINATION 101 TOTAL LOAD
    1 1. 2 1. 

A load combination case, identified with load case number 101, is specified above. It instructs STAAD to factor loads 1 and 2 by a value of 1.0 and then algebraically add the results.

    PERFORM ANALYSIS

The analysis is initiated using the above command.

    LOAD LIST 101
    PRINT JOINT DISPLACEMENTS LIST 33 56
    PRINT ELEMENT STRESSES LIST 34 67

Joint displacements for joints 33 and 56, and element stresses for elements 34 and 67, for load case 101, is obtained with the help of the above commands.

    FINISH

The STAAD run is terminated.
