How do you find the midpoint in Etabs?
Select joints to calculate midpoint. In your ETABS model select two reference joints and then click on “Extract coordinates of two selected joints” in the plugin’s interface, so the program can calculate the midpoint (see Figure 12) and define the reference line between the two points.

Why soil structure interaction is important?
Considering soil-structure interaction makes a structure more flexible and thus, increasing the natural period of the structure compared to the corresponding rigidly supported structure. Moreover, considering the SSI effect increases the effective damping ratio of the system.
What is isolated footing?
An isolated footing is one of the most used types of foundation to support single-columns when they are arranged at a long distance. An isolated footing must be designed to avoid exceeding its bearing capacity and provide safety against overturning or sliding while preventing the ground from settling.

What is insertion point in Etabs?
The insertion point relates the actual position of an object to the line drawn to represent that object in a model. This will position the girder below the line which represents its location.
How do you build a raft foundation manually?
The maximum settlement should generally be limited to the following values: Raft foundation on clay – 65 to 100 mm. Raft foundation on sand – 40 to 65 mm….2) Soil line Method (Elastic Method) of Raft Foundation Design.
| Soil Characteristics | Ks(Kg/cm2) | |
|---|---|---|
| 1. Stiff | 1 to <2 | 2.7 |
| 1. Very Stiff | 2 to <4 | 5.4 |
| 3. Hard | 4 and over | 10.8 |
What do you mean by soil structure interaction?
Under earthquakes, the structural displacements and the ground displacements are not independent of each other. The response of the soil influences the motion of the structure and the motion of the structure influences the response of the soil. This is called as soil-structure interaction (SSI).
What are the soil properties which are influenced by soil structure Mcq?
What are the Soil properties, which are influenced by soil structure? Explanation: Soil structure is an important factor which influences many soil properties such as permeability, compressibility, and shear strength. Explanation: Single grained structure is usually found in coarse-grained soil.
