EX. UK-2 Area Load Generation on Floor Structure

A floor structure (bound by global X-Z axis) made up of steel beams is subjected to area load (i.e., load/area of floor). Load generation based on one-way distribution is illustrated in this example.

In the case of loads such as joint loads and member loads, the magnitude and direction of the load at the applicable joints and members is directly known from the input. However, the area load is a different sort of load where a load intensity on the given area has to be converted to joint and member loads. The calculations required to perform this conversion are done only during the analysis. Consequently, the loads generated from the AREA LOAD command can be viewed only after the analysis is completed.

This problem is installed with the program by default to C:\Users\Public\Public Documents\STAAD.Pro CONNECT Edition\Samples\Sample Models\UK\UK-2 Area Load Generation on Floor Structure.STD when you install the program.

Example Problem No. 2

Where:

  • W1 = 1.5 m, W2 = 1.0 m, W3 = 1.5 m, L1 = 2.0 m, L2 = 4.5 m, L3 = 3.0 m

Actual input is shown in bold lettering followed by explanation.

   STAAD FLOOR A FLOOR FRAME DESIGN WITH AREA LOAD

Every input has to start with the term STAAD. The term FLOOR signifies that the structure is a floor structure and the structure is in the x – z plane.

   UNIT METER KNS 

Defines the input units for the data that follows.

   JOINT COORDINATES 
   1 0 0 0 5 6 0 0 ; 7 1.5 0 3 
   8 3 0 3 ; 9 4 0 3 ; 10 4.5 0 3 ; 11 5 0 3

   19 6 0 8.5 ; 20 0 0 10.5 ; 21 6 0 10.5 

Joint numbers followed by X, Y and Z coordinates are provided above. Since this is a floor structure, the Y coordinates are all the same (in this case, zero). Joints between 1 and 5 (i.e., 2, 3, 4) are generated in the first line of input, taking advantage of the equal spacing between the joints (refer to TR.11 Joint Coordinates Specification for more information).

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

Defines the members by the joints to which they are connected.

   MEMB PROP BRITISH

Member properties are specified from the British steel table. The term ST stands for standard single section.

The first set of members (1 5 10 etc) have local moment-z (MZ) released at the start joint. This means that these members cannot carry any moment-z (i.e., strong axis moment) at the start joint. The second set of members have MZ released at the end joints.

Define the material properties for steel. The units are changed to millimeters and then back to meters in order to facilite inputing the values in familiar units.

   CONSTANT

A fixed support has been specified at the above joints.

   LOADING 1 14.5 KN/sq.m. DL+LL

Load case 1 is initiated followed by a title.

FLOOR LOAD
YRANGE -0.5 0.5 FLOAD -14.5

All members within a range of -0.5 meters to 0.5 meters in the global Y direction (which is the entire floor of this model) are subjected to an floor load of 14.5 KN/sq.m. The program converts area loads into individual member loads.

   PERFORM ANALYSIS PRINT LOAD DATA

This command instructs the program to proceed with the analysis. The PRINT LOAD DATA command is specified to obtain a listing of the member loads which were generated from the FLOOR LOAD.

   PARAMETERS
   CODE BRITISH
   BEAM 1 ALL
   DMAX 0.6 ALL
   DMIN 0.3 ALL
   UNL 0.3 ALL 

The PARAMETER command is used to specify steel design parameters (refer to D3.B.6 Design Parameters). Design is to be performed per the specifications of the BS 5950 2000 Code. The BEAM parameter is specified to perform design at every 1/12th point along the member length. DMAX and DMIN specify maximum and minimum depth limitations to be used during member selection. UNL is used to specify unsupported length of the compression flange to be used for calculation of allowable bending stress.

   SELECT MEMB 2 6 11 14 15 16 18 19 21 23 24 27

The above command instructs the program to select the most economical section from the British steel table for the members listed.

   FINISH

The FINISH command terminates the STAAD run.
