Effect of shear wall on l-shaped buildings

Published on 16 Apr 2022. Written by Akshay

Construction of buildings is usually done on flat grounds, but due to the scarcity of flat grounds buildings are constructed on sloping grounds. Sloping grounds are those which are at an inclined level from the normal ground.

Building shapes: There is a variety of building shapes, like rectangle, I, L, M and among these, L-shaped buildings utilize natural environmental conditions to achieve most of the inside or outside comfort for building users.

Basic terms: There are many types of displacements like lateral displacement, story drifts, and story displacements and also factors, like story acceleration, time-period, etc. The introduction of a reinforced concrete wall called a shear wall is used in this project.

Lateral displacement, Story drift is more for L-shaped buildings when compared to other buildings thus shear wall is used to reduce the story displacement.

The nature of structures built on sloping ground is unsymmetrical and hence it attracts a large number of shear forces and torsional moments and shows unequal distribution due to varying column length.

Asymmetric planned buildings affect more because it has more lateral displacement. To improve Seismic performance shear wall on a building is helpful when carried and analyzed.

In this project, we will study the impact of the shear wall when applied to both flat ground and sloping ground.

Since we discussed there are various parameters such as base shear, story displacement, and story drift. But for a complete understanding of the project values and results, we have considered only important parameters such as base shear, story displacement, and story drift.

Objectives

1. To Model and Analyze L-Shaped Multi-story building resting on Flat and Sloping Ground.
2. To compare the results of Base shear, Story displacement, Story drift of building without developing the shear wall.
3. To find the effective position of the Shear wall in a building.
4. To determine and compare the effect of the Shear wall on a building resting on Flat ground as well as Sloping ground.

Methodologies

• Response spectrum analysis
• Equivalent static method

Software required

• SAP-2000
• E-Tabs

Conclusion:

1. Base shear is more for building resting on Flat ground when compared to that of Sloping ground due to high Seismic weight.
2. On Provision of Shear Wall, Variation in Base shear is more for building resting on the sloping ground due to the increase in the number of a position in the shear wall.
3. Shear wall provision reduces story displacement.
