EX. US-17 User-Provided Tables

The usage of user-provided steel tables is illustrated in this example for the analysis and design of a plane frame. User-provided tables allow you to specify property data for sections not found in the built-in steel section tables.

This problem is installed with the program by default to C:\Users\Public\Public Documents\STAAD.Pro CONNECT Edition\Samples\Sample Models\US\US-17 User-Provided Tables.STD when you install the program.

Example Problem No. 17

Where:

  • L1 = 15 ft, L2 =20 ft
  • P = 5.0 k
  • w = 3.0 k/ft

Actual input is shown in bold lettering followed by explanation.

    STAAD PLANE EXAMPLE FOR USER TABLE

Every input file has to start with the command STAAD. The PLANE command is used to designate the structure as a plane frame.

    UNIT FT KIP

The UNIT command sets the length and force units to be used.

    JOINT COORDINATES
    1 0. 0. ; 2 30 0 ; 3 0 20 0 6 30 20 0
    7 0 35 ; 8 30 35 ; 9 7.5 35 ; 10 22.5 35.
    11 15 35 ; 12 5. 38. ; 13 25 38 ; 14 10 41 ; 15 20 41
    16 15 44

The above set of data is used to provide joint coordinates for the various joints of the structure. The Cartesian system is being used here. The data consists of the joint number followed by global X and Y coordinates. Note that for a space frame, the Z coordinate(s) need to be provided also.

Note: Semicolons (;) are used as line separators to allow for input of multiple sets of data on one line.

    18 10 15 ; 19 10 13 ; 20 7 9
    21 9 11 ; 22 10 11 ; 23 8 10

The above data set contains the member incidence information or the joint connectivity data for each member. This completes the geometry of the structure.

    START USER TABLE

This command is utilized to set up a user-provided steel table. All user-provided steel tables must start with this command.

    TABLE 1

Each table needs an unique numerical identification. The above command starts setting up Table no. 1. Up to twenty tables may be specified per run.

    UNIT INCH
    WIDE FLANGE

This command is used to specify the section-type as WIDE FLANGE in this table. Note that several section-types such as WIDE FLANGE, CHANNEL, ANGLE, TEE etc. are available for specification ( see TR.19 ユーザー鋼材テーブルの設定 ).

    WFL14X109
    32. 14.32 .525 14.605 .86 1240 447 7.12 7.52 16.

The above data set is used to specify the properties of three wide flange sections. The data for each section consists of two parts. In the first line, the section-name is provided. You are allowed to provide any section name within twelve characters. The second line contains the section properties required for the particular section-type. Each section-type requires a certain number of data (area of cross-section, depth, moment of inertias etc.) provided in a certain order. For example, in this case, for wide flanges, ten different properties are required.

    2.5 2.5 .3125 .489 0 0
    LANG40404
    4 4 .25 .795 0 0 

The above command and data lines set up another user provided table consisting of angle sections.

    END

This command signifies the end of the user provided table data set. All user provided table related input must be terminated with this command.

    8 TO 13 UPT 1 WFL14X30
    14 TO 23 UPT 2 LANG40404

In the above command lines, the member properties are being assigned from the user provided tables created earlier. The word UPT signifies that the properties are from the user-provided table. This is followed by the table number and then the section name as specified in the use- provided table. The numbers 1 or 2 following the word UPT indicate the table from which section names are fetched.

    MEMBER TRUSS
    14 TO 23

The above command is used to designate members 14 to 23 as truss members.

    MEMBER RELEASE
    5 START MZ

The MEMBER RELEASE command is used to release the MZ moment at the start joint of member no. 5.

The DEFINE MATERIAL command is used to specify material properties and the CONSTANT is used to assign the material to all members.

    UNIT FT

The length unit is reset to feet using this command.

    UNIT FT

The length unit is reset to feet using this command.

    SUPPORT
    1 FIXED ; 2 PINNED

The above command set is used to designate supports. Here, joint 1 is designated as a fixed support and joint 2 is designated as a pinned support.

    LOADING 1 DEAD AND LIVE LOAD
    SELFWEIGHT Y -1.0 
    JOINT LOAD
    4 5 FY -15. ; 11 FY -35.
    MEMB LOAD 
    8 TO 13 UNI Y -0.9 ; 6 UNI GY -1.2

The above command set is used to specify the loadings on the structure. In this case, dead and live loads are provided through load case 1. It consists of selfweight, concentrated loads at joints 4, 5 and 11, and distributed loads on some members.

    PERFORM ANALYSIS

This command instructs the program to execute the analysis at this point.

    PARAMETER 
    CODE AISC UNIFIED
    BEAM 1.0 ALL
    NSF 0.85 ALL
    KY 1.2 MEMB 3 4

The above commands are used to specify parameters for steel design.

    SELECT MEMBER 3 6 9 19

This command will perform selection of members per the AISC ASD steel design code. For each member, the member selection will be performed from the table that was originally used for the specification of the member property. In this case, the selection will be from the respective user tables from which the properties were initially assigned. It may be noted that properties may be provided (and selection may be performed) from built-in steel tables and user provided tables in the same data file.

    FINISH

This command terminates a STAAD run.

    2. Results for any Capacity/Check that is not relevant for a section/loadcase
       based on the code clause in AISC 360-16 will not be shown in the report.     
    3. Bending results are reported as being �about� the relevant axis (X/Y), while 
       the results for shear are reported as being for shear forces �along� the axis.
       E.g : Mx indicates bending about the X axis, while Vx indicates shear along
       the X axis.
