8. Methods of analysis
1. Flexibility coefficient method. 2. Slope displacement method. 3. Iterative methods like a. Moment distribution method(By Hardy Cross in 1930’s) b. Kani’s method (by Gasper Kani in 1940’s) 4. Approximate methods like a. Substitute frame method b. Portal method

9. STIFFNESS METHOD
The stiffness analysis implemented in STAAD is based on the matrix displacement method
In the matrix analysis of structures by the displacement method, the structure is first idealized into an assembly of discrete structural components (frame members or finite elements).
First structural software which adopted Matrix Methods for the method of analysis was STAAD

13. Shear walls are especially important in high-rise buildings subjected to lateral wind and seismic forces
Shear wall buildings are regular in plan and in elevation. However, in some buildings, lower floors are used for commercial purposes.
