EX. UK-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\UK\UK-17 User-Provided Tables.STD when you install the program.

Example Problem No. 17

Where:

• L1 = 4.5 m, L2 = 6.0 m
• P = 25 kN
• w = 45 kN/m

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 METER KNS
```

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

```    JOINT COORDINATES
1 0. 0. ; 2 9 0 ; 3 0 6 0 6 9 6 0
7 0 10.5 ; 8 9 10.5 ; 9 2.25 10.5 ; 10 6.75 10.5
11 4.5 10.5 ; 12 1.5 11.4 ; 13 7.5 11.4
14 3.0 12.3 ; 15 6.0 12.3; 16 4.5 13.2
```

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.
```    MEMBER INCIDENCES
1 1 3 ; 2 3 7 ; 3 2 6 ; 4 6 8 ; 5 3 4
6 4 5 ; 7 5 6 ; 8 7 12 ; 9 12 14
10 14 16 ; 11 15 16 ; 12 13 15 ; 13 8 13
14 9 12 ; 15 9 14 ; 16 11 14 ; 17 11 15
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 CM
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 User Steel Table Specification ).

```    BEAM250
32.2 25.5 0.6 10.2 0.85 3400 150 6.2 15.7 15.4
BEAM300
47.5 30.4 0.72 12.4 1.07 7160 335 14.3 21.9 23.8
BEAM350
64.6 35.6 0.73 17.2 1.15 14150 970 22.8 26.0 35.5
```

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.

```    TABLE 2
UNIT CM
ANGLES
L30305
3.0 3.0 0.5 0.58 1.0 1.0
L40405
4.0 4.0 0.5 0.78 1.33 1.33
L50505
5.0 5.0 0.5 0.98 1.67 1.67
```

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.

```    MEMBER PROPERTIES
1 3 4 UPT 1 BEAM350
2 UPT 1 BEAM300 ; 5 6 7 UPT 1 BEAM250
8 TO 13 UPT 1 BEAM250
14 TO 19 UPT 2 L30305
20 TO 23 UPT 2 L40405
```

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.

```    UNIT MMS
DEFINE MATERIAL START
ISOTROPIC STEEL

END DEFINE MATERIAL
CONSTANTS
MATERIAL STEEL ALL
BETA 90.0 MEMB 3 4
```

The above command set is used to specify modulus of elasticity, density, Poisson’s ratio and beta angle values. Built-in default value of steel is used for the material constants.

```    UNIT KNS METER
```

The force unit is reset to KNS, and length unit to METER 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
4 5 FY -65. ; 11 FY -155.
8 TO 13 UNI Y –13.5 ; 6 UNI GY –17.5
```

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 EN 1993-1-1:2005
NA 1
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.

```    CHECK CODE MEMBER 3 19
SELECT MEMBER 20
```

This command will perform a code check on members 3 and 19 per the Eurocode 3 steel design code with the UK National Annex. A member selection too is performed for member 20. 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.
