Conceptual design of a building with columns and shear walls

1. Ans:

Critera	Diagram A	Diagram B	Diagram C0
Restraint of floor shrinkage	The corner are stiffness so full restraint at corner	The corner are free so it has restraint at corner	This is non uniform structure with restraint
Lateral Stiffness	Comparatevely low lateral stiffness along X and Y	Uniformly and high lateral stiffness	Non unifrom lateral stiffness
Torsional respect to vertical axis	The corner are fixed have high torsional resistances	The corner are free it is good at torsional but it is low compare to Diagram A	It has very low torsional twist resistance
Vertical reinforcement for similar base capacity	It has low flexural Moment and torsional twist Moment	It has low Torsional twist Moment	It had high flexural Moment and torsional twist Moment

Static eccentricity	Structural symmetry	Structural symmentry	Un symmentry, and have high eccentricity
Foundation systems	The L shaped wall which is leads to complex in desing	The wall are in line and isolated footing	The wall are not in line and design of strucutre is more complex
Architectural	Wall obstract only corner	Wall obstract on the center.	Wall obstract at passage

2. Ans:

• Internal load Tansfer along X and Y direction The beams along the plas are not in line and which leads to lateral load failure
• This can not transfer the load to the column completely.

Eccentricity:

• The longer the distance of center of mass and center of stiffness which leads to the failure
• The torsional Moment along both x and y direction which leads to failure

Strong Beam and weak Column :

• In the first line in X direction the beams size is 25*50 and column size is of 25 *25.
• This leads to strong in beam and weak in column overall shear will be act on the column which leads to failure in column

3. Ans:

Floor Plan :

• The oveal all 100 % of lateral force will not converted to another end because of non uniform strucutre , the By directional flow in not applicable.

Random Internal columns:

• There is no uniform placement of column in the strucutre which leads to random distrubiton of load.

Floor to Floor beam and partition of room :

• There is different in beam and wall along all floors which leads to varation in loads on each floor which leads to failure of building.

• Heavy torsional load can be controlled by lateral load system which leads to shear wall .
• The area of onside of the building is high and compare to other which means onside has large corner shear wall compare to other.
• The Corner shear wall can be connected to Box foundation.
• Where the Column in inner are connected to Isolated foundation
• The column along isolate foundation will be connected to Corner shear wall with box foundation by using Tie beams.
