Evaluation of Lateral Stability of Cantilever wall By Dr. Prashant Pawar

 Purpose and Background of product:

Recently in Maharashtra there were accidents Of collapse of compound and walls of building.During careful evaluation of these accidents,it was noticed that these walls are collapsed due to insufficient stability of these walls.

 Brief Description of product : 

This Product will be useful to test the destructive testing of existing walls also this device:

1. This device has a portable cantilever column which will be fixed near the walls parallel to the walls.

2. The height of the column is about 1.5m which helps in varying the height of the Lateral point where load can be applied with respect to LG of wall based on the Height.

3. Horizontal hydraulic jack is connected perpendicular to the wall connecting to the vertical column.This jack is useful for applying the horizontal load.

4. There is a load cell connected between wall and loading jack which measures the amount of load applied.

5. Dial guage is also connected between wall and vertical cantilever column to measurethe deflection of wall.

Procedure to use the Device :-

The Procedure is explained using the sigure-I

1. Connect the load cell shown as 3 to the wall shown as 1 using the base plate

shown as 2.

2. Erect the vertical steel column parallel to wall.as shown in 5 using anchors

shown as 7.

3. Connect the hydraulic damper as shown in 4 between load cell as shown in 3.

4. Connect the dial guage between wall (1) and vertical column (5) to measure the

deformation due to load.

5. Gradually apply the load and measure the deformation.

6. Plot the graph of force vs displacement the slope of the graph is measured as

stiffness.

Outcomes to be Measured:

1.      Lateral stiffness of wall using load vs deflection graph.

2.       Failure load of wall.

3.      Failure patterns of the wall.

4.      Above results can be obtained along the force or thickness of wall.
