Maintain Lintel Data Sub-command

12.2.1 Maintain Lintel Beam Data(Classical)

The Maintain Lintel Beam Data sub-command is use to create a new lintel beam data or edit existing lintel beam data and supply the vertical loads or amend existing loads of lintel beam data.

When you choose Maintain Lintel Beam Data from Lintel Command or click button on

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

the Maintain Lintel Beam Data window.

The Maintain Lintel Beam Data sub-command have two pages. 1. Lintel Beam Data Page.

2. Lintel Beam load Page.

Existing Lintel Beam Mark Group box : Indicate the listing of the existing lintel beam marks

which have previously created. You may use button that appears under the box to rearrange

the order of the existing lintel beam mark. Followed the steps of List ox at Window component.

You may search the desired Lintel beam mark followed the steps of Incremental earch at

"Window component" topic in "How to use SADS" chapter.

Control Data Group Box :

Lintel Mark - Enter alphanumerical up to 8 characters long for lintel beam mark.

Located at Wall - Enter the wall mark where the lintel beam located. (Available for Classical

Method only)

Design Method Group Box : Click the radio button and select the "Classical Method" or "Three

Dimension Method" you use.

Direction Group Box : Click the radio button and select "X-X", if the span of lintel beam is at X-X

direction of wall coordinates. Select "Y-Y", if the span of lintel beam is at Y-Y direction of wall coordinates.

Lintel Beam Data Group box : The following information is for "Classical Method". Floor - The floor ode of the building.

Floor Name - Click the radio button and enter the description of corresponding floors which the

lintel beam should be calculated. If there is no lintel beam on the specific floor, you may skip the row.

t - Enter the thickness of wall (in mm) where the lintel beam located.

T - Enter the total thickness of wall's webs (in mm) which parallel to the axis of lintel beam. X - Enter the x-distance (in M) of mid point of lintel beam span to the X-axis of wall coordinates. Y - Enter the y-distance (in M) of mid point of lintel beam span to the Y-axis of wall coordinates.

Cover - Enter the concrete cover (in mm) of lintel beam.

Kt - Enter the value of Coefficient of torsional stress, it's value should be calculated from:

t t M t K =t´ Where:

r is the shear stress, it's formula can be found from Designer's Handbook; t is the thickness of wall where lintel is located;

Mt is the torsional moment of core wall.

Example: b h t bht Mt 2 = t bh M t K t t 2 1 = ´ =t

Load Code - Enter up to 8 characters long for the name of vertical load code of lintel beam.

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

12.2.2 Maintain Lintel Beam Data(3 Dimension)

If the Method you use is the "Three Dimension Method", the Lintel Beam Data Page is as below.

The Lintel Beam Data Group Box of the Three Dimension Method has difference fields from Classical Method, it consists of following fields:

Floor - The floor ode of the building.

t(mm) - Enter the thickness of wall (in mm) where the lintel beam located. L(M) - Enter the span (in M) of lintel beam.

B(mm) - Enter the width (in mm) of the lintel beam section. D(mm) - Enter the depth (in mm) of the lintel beam section. Cover(mm) - Enter the concrete cover (in mm) of lintel beam.

Check - Check the check box if you want to check the section of the lintel beam on this floor. Load Code - Enter up to 8 characters long for the name of vertical load code of lintel beam

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

processing.

12.2.3 Maintain Lintel Beam Load

Click the Lintel Beam Load Code Page, SADS will display the Lintel Beam Load Code Page as below. The Lintel Beam Load Code Page allows you to supply the Load Code data you created in the Maintain Lintel Beam Data Page or amend the loading of existing load code.

Existing Lintel Beam Load Code Group box : Indicate the listing of the existing lintel beam load

code that created at above page. You may search the desired Lintel beam load code followed the

steps of Incremental earch at "Window component" topic in "How to use SADS" chapter.

Header Data Group Box : Enter the load code which you want to supply vertical loads data in it. Lintel Loads Group box :

Name - Enter the name of load. If it is slab or beam, the load name must be exactly same as

the slab mark or beam mark which have been previously defined in the framing plain

Load Type - Enter the type of load which applied on the lintel beam. SADS defined the loading

type as followed:

0 -- uniformly distributed load on full span, unit: kN/M. 1 -- concentrated load, unit: kN.

2 -- uniformly distributed load, unit: kN/M. 3 -- triangular distributed load, unit: kN/M. 4 -- trapezoidal distributed load, unit: kN/M. 5 -- right triangular distributed load, unit: kN/M. 6 -- right triangular distributed load, unit: kN/M. 7 -- concentrated moment load, unit: kN- M.

Attribute - Click the combo box and select the source of loading. "B" denotes beam, "S"

denotes slab, "C" denotes column, SADS will automatically extracts the reactions upon them. If you do not want SADS automatically extracts the reactions, select blank " ", then you may enter the dead load and live load of the loading in the appropriate box.

Flag - Click the combo box and select the characteristic of the loading. For beam, you may

select "R" "L", "R" denotes right hand side reaction, "L" denotes left hand side reaction. For slab in 8110, you may select "C" "D", "C" denotes continuous slab, "D" denotes discontinuous slab.

D.L. - Enter the value ( in kN or kN/M) of dead load.
