Conceptual design of a building with columns and shear walls

1.

sr no	fig1	fig.2	fig.3
1) restarin of floor shrinkage	full restraints AT ALL corners	cornres are left free but restraints along the edge	non unifrom restrints
2) the lateral stiffness	compertively lower lateral stiffness in both x and y direcation	unifromly and compartively higher lateral stiffness in both x and y dircation	non unifrom lateral stifness in both x and y dircation
3)torsion with respect ton vertical axis	corenrrs wall provide more resisitnce to tiwst	edge wall provide good resistnce to twist	irregular wall provide very poor resistnce to twist
4) vertical rainforcement for similer base capacity	wall are sub to nomial flexural moment and heavy twisting moment	wall are sub to nomial twisting moment	wall are sub to heavy flexural moment and twisting moment
statice eccentricity	structurally symmetical	structurally symmetical	structurally un-symmetical
5) system s redundancy	unifrom placement of lateral load support in both the axes	unifrom placement of lateral load support in both the axes	concentrede latera load support in both the axes
6) foundation system	due to l shaped wallthe geomenetry of foundation and its design will be crictical	wall are in line .easy to fix the geomentry and design of foundation	wall are in line & concentered.easy to fix the geomentry foundation but critical to desgin

Indirect lateral load transfer in X and Y directions - The beams are connecting to another beams which is ineffective during lateral load transfer. In suchconditions, the primery beam is prone to shear failure.

ecenticity- the longer the distance between center of mass and center of stiffness, the hogher torsional moment of the building.as per the given plan ecentricity, the building is subjected to higher trosionalmoment (torsional flexibility )in both x and y direcation.

strong beam weak column possibilty:- the size of columns majorly mentioned as 25*25 cm but all the beams have much deeper section 50 cm. inertia of beamis vaisally higher than coulmn .if the column reinforcmet is adequatelty greter than that beam wr are ok and sinces we do not have the rainforcement detail this is doubtful its recommended to have slight bigger size for column

3.

FLOOR PLAN- THE FLOOR PLAN OF BUILDING is not either unifrom or symmentric so naturally any lateralload induced in the floor will not have 100% influenece in same direcation. difenitley a speecial lateral load resisting system for these torsionalmoments should be accommodated.

Random intrnal column-since the intrnal coulmn are randomly they are unable to transfer latderal loade efficentlyand can notacchived desirable building responces. so we have to assum and design those column for only gravity lods.

floor to floor varriation in partition wall and beam-partion wall provied an importance mass control in a building and beam play key role an shear transfer floor to beam.all this elemnts are not inoder.so heavy distrition and distributionof lateral lods will happen.
