DESIGN OF GLOBE VIEW RESIDENTIAL BUILDING
• Introduction
The proposed site is located at Queenhithe and near river Thames and close
to Millennium Bridge. The area contains a residential building known as
Globe view that provides a clear view of River Thames. The total area of the
site is approximately 235.1 square meters and the building consists of two
bedrooms.
• Construction work and sequences
Construction of the residential building would involve the following;
a.Paper work
b. Layout mark
c.Foundation work
d.Footing concrete
e.Column casting
f.Wall construction
g.Roofing
h.Fixing windows and doors
i.Electrical and plumbing work
Detailed design
1. Slab design
Span
a. Shorter span:- Lx = 5.8 m
Longer span:-Ly =7.6 m
b. Check Lx/Ly= 7.6/5.8 =1.3<2 (the slab will be designed as two way slab)
c. Take the overall slab depth be = 120mm and cover depth be 15 mm
Effective depth= Depth -15- /2 =120-15-10/2=100mm
d. The slab is supported on its four sides.
e. Calculation of loads:

BEAM DESIGN
Beam member in a building helps in transferring slab load to column
and for foundation into the soil
Slab span would determine the beam spacing
Loads that acts on the beam includes; Live load, dead load and wind
load
Beam loads
• Beam: B1
• Design of stirrups
Beam: B1
• Design of stirrups
Beam: B2
Beam design
Mu @ left span = 11.6 kN-m
Mu @ Mid span = 19.2 kN-m
Mu @ Right span = 20.4 kN-m
COLUMNS DESIGN
Column are regarded as compression members
Columns transmits load from the slab to the foundations
Considerations are always placed in place to avoid use of large span
beams to control cracking and deflection
Conclusion
The slabs were designed based on the relationship of the ratio between
longer to shorter span of panel. Therefore, the slab in this case was
designed as two way slab based on the end condition, that would
correspond to bending moment. The coefficient calculated
corresponded to lx/ly ratio. The calculation for loads on columns and
beams in addition to designed frame using moment distribution were
done.
