PDE 1720 Structural Design: Globe View Residential Building Project

The assignment focuses on the structural design of a residential building, specifically the Globe View Residential Building. The project involves detailed calculations and considerations for various structural elements, including slabs, beams, and columns. The design process begins with an introduction to the building's location and purpose, followed by detailed design aspects such as material selection, construction methods, and adherence to building regulations. The solution includes calculations for slab design, beam design, and column design, detailing the loads, bending moments, and structural member sizes. The slab design considers two-way slab behavior based on span ratios. The beam design covers load calculations, and the column design emphasizes compression members. The project aims to demonstrate an understanding of structural design principles, material selection, and construction techniques within a domestic house context. The project uses calculations to determine the size of the structural elements. The end result is a comprehensive structural analysis of the residential building. The assignment adheres to the guidelines of the PDE 1720 course, requiring the creation of A2-sized posters to present the findings and design choices.

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.
