Conceptual design of a building with columns and shear walls

1.

2.

Indirect lateral load transfer in X and Y directions:

          The beams are connecting to another beams which is ineffective during lateral load transfer. In such conditions, 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 we are okay 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 the 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 loads.

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.
