Column size = 400 x 400The compression axial load for the load combination of (1.5 DL + 1.5 LL) is 2000 KNThe safe soil bearing capacity is 150 KN/m2 at foundation depth below E.G.L = 2 metres Grade of concrete for footing = M25Footing sizecolumn load 2000KN10% of footing self weight + 2000x10/100+ 200KNAxial load…

Data required for ETABS analysisPinned support, Base + 9 story (ground to terrace)+ 1 mumtyAssume Column 450mm x 600mm, Beam 400mm x 500mm, Slab 150mm thick, Shear wall 300mm thick.Live load 2.5 KN/m^2, Floor finish 1.5 KN/m^2, Wall load 5 KN/m, Water tank 20k litre over mumty equivalent to 200 KN overall load.Conceptual…

The o/s in the beam represents the over shear stress in the represent beam. So shear stress is load/area so we can reduce the load or increase the area to minimize the shear stress. And also we can increase the shear capacity by increasing the grade of concrete.Longitudinal reinforcingShear reinforceSway shear

CRITERIAMODELANALYSIS RESULTCONCLUSIONEffect of stiffness on time periodBuilding E (10 storey with varying column size)1.731 sThe varying column sized building is more stable than the uniform sized column buildings because in uniform sized column building the excess mass is lumpded in the storey and it increases by the…

The fundamental translational natural period at X- direction is 4.58 and Y- direction is 4.37 therefore it is approximately equal to the value given.The torsional mode time period is lesser than X and Y direction time periods.First three modes together should contribute atleast 65% in mass participation factor in each…

1.CRITERIAFigure (a)Figure (b)Figure (c)Restraint floor shrinkageObservationFull restraints at all corners Corners are left free but restraints along the edgeNon uniform restraints ConclusionFigure (a) will have higher restraint to shrinkage. thus lead to cracks in the floor. Figure (b) is average. Figure (c)…

1.Investigation of the framing plan with respect to symmetry in X-direction:If we split the plan vertically half, it will look mirrored. So we conclude the given plan is symmetric in X-direction.Investigation of the framing plan with respect to symmetry in Y-direction:If we split the plan horizontally half, it will look…

Answer

1.STATIC ANALYSISStatic analysis can only be performed if the system being simulated does not depend on time, and if the loads being applied are constant.Static analysis don't consider inertia.Static refers to the force that has constant size, position direction on or within a structure.There is no necessity to count inertia…

1.a)ObservationConcrete crushed and the reinforced is exposed.Concrete spalled beyond the reinforcement which may be a sign of rupture.Beam top portion looks safe because of the flange advantage from slab.The crack develops from bottom to top means rebar yielding occurs in support bottom only.Result & ConclusionIts…
