Maintain Batch Data Sub-command

The Maintain Batch Data sub-command is use to define the whole circumstances about continuous beams of the building in each batch code for the requirement of calculation. Each continuous beam must has a batch data, even it is a simply supported beam. The batch data consists of beam span number, type of continuous beam, information of support, wind loads applied to beam, etc., which combined together for the detail of a continuous beam.

When you choose Batch Data from Beam command of the Module menu or click button on

Command utton ar then click button on Sub-command utton ar , SADS will display

Batch Code - Click the combo box , the listing of the individual batch codes of the beams are

previously define in the Batch Code sub-command of the System Command. You may search the

desired batch code followed the steps of Incremental earch at "Window component" topic in

"How to use SADS" chapter.

Existing Batch Data Group box - Indicate the listing of the relevant batch data of the selected

batch code. There is a button under the box, so you can rearrange the order of the existing

beam marks, followed the steps of List ox at "Window component" topic in "How to use SADS"

chapter. If you want to search the desired batch data, you may follow the steps of Incremental earch at "Window component" topic in "How to use SADS" chapter.

Header Data Group Box : This group include a series of information use to define the whole

circumstances of continuous beam.

Span Number - Enter the span number of a continuous beam. SADS provides the maximum

span number is 21.

Type - Click the combo box and select the type of continuous beam. SADS defined the type in

5 different kinds, you may type the number in this field. (i.e., type "0" for single span simply supported beam). The following figure shows you graphically about the type of continuous beam.

0 -- Indicates single span simply supported beam;

1 -- Indicates continuous beam in that the both ends are supported; 2 -- Indicates continuous beam that the left end is cantilever; 3 -- Indicates continuous beam that the right end is cantilever; 4 -- Indicates continuous beam that the both ends are cantilever.

0: Single span simply supported beam.

1: Continuous beam which both ends are supported.

2: Continuous beam which left end is cantilever.

3: Continuous beam which right end is cantilever.

4: Continuous beam which both ends are cantilever.

Direction - Click the combo box and select the condition of continuous beam, SADS defined

as N, X, Y and B. You may select the correspondence symbol in it.

"N" -- Indicates all supports of continuous are hinged and no need to enter support mark.. "X" -- Indicates the supported of continuous beam are columns, the direction of continuous

beam span is in X-axis of columns.

"Y" -- Indicates the supported of continuous beam are columns, the direction of continuous

beam span is in Y-axis of columns.

"B" -- Indicates the supported of continuous beam are beams or walls, and you want to enter

the support marks.

Floor Code - Click the combo box and enter the floor ode of the continuous beam. If the type of batch data is "0", this box will be disabled.

Beam Mark Group Box : Enter the marks of continuous beam of the batch data. If it is located

along X-X direction, the order should be from left to right, if it is located along Y-Y direction, the order should be from bottom to top, if it is use on the girder that support any column as shown in below figure, SADS named the girder as GB2. From the point of frame analysis the girder should be consider as two elements, it should have two difference marks. SADS named them as

"associate beams" e.g. GB2a and GB2b, there may up to 10 associate beams on one girder. If you had previously defined the girder and entered the associate beam data, then the beam mark changed to cyan base and red letter, as the displayed of above figure.

GB1 GB2a GB2b GB3

GB2

If the beam is a girder, click button, SADS will display the dialog box show as below and allow

Enter the name of associate beams and the length of each associate beam (the overall lengths of associate beams must equal to the length of the girder).

Besides, in the output of Beam design sub-command, SADS will only shown the girder as beam GB1, no GB1a or any associate beam.

Note: When input relevant column data of the girder, you should enter the girder mark rather then

the associate beam mark, i.e. GB1 for column C1 and C3 and the width of column C2 on ground floor should be zero. The associate beam marks will be shown only in the frame sketch.

Support Group Box : Enter the support marks and types of the continuous beam.

1. If the support is column, enter the column mark and select the type as "CL". SADS will consider the stiffness of the column to the analysis of the continuous beam and calculate the support moment by considering the width of columns.

2. If the support is beam, enter the beam mark, and select the type as "BM". SADS will calculate the support moment by considering the width of support beam.

3. If the support is hinge support, enter "N", and select the type as "HN". SADS will calculate the support moment at the center of support.

4. If the ends support of continuous beam is walls, and the direction of walls are same with the direction of beam span, (i.e. fixed support), enter "F", and select the type as "FX".

5. If it is the free end of cantilever beam, enter "N" and select the type as "NA".

Wind Load Group Box : This group consist of two elements, first floor code and last floor code.

Click the Combo box and select the first floor code and the last floor code which should be considered the wind load, dynamic load and soil load in the calculation of the continuous beam.

SADS provided up to 7 cases in a continuous beam, and will automatically find out the worse case

for the calculation of the continuous beam.

First floor code indicates the top level of every case. Last floor code indicates the bottom level of every case.

If you want to copy the First floor codes and Last floor codes to other batch data, you may click the button to copy these floor codes to clipboard. When you open batch code that has the same

list of floor codes, you may click the button to copy these floor codes from clipboard to Lateral

click the button.

You may use the common uttons at the lower part of the window to manipulate the data

processing.
