a. COURSE DESCRIPTION
The course is a continuation of Arc 325 (Building Structures IV).The goal of the course to further expose the
students to the rudiments of reinforced concrete design. Emphasis is the design of basic structural elements
such as beams, slabs, columns, and retaining walls
b. COURSE OBJECTIVES
At the end of this course, students are expected to be able to do the following
 Design simply supported RC beam showing details of the reinforcement placement
 Design a RC slab
 Design a column section, simple pad footing
 Ultimately, the student should be able to understand and interpret structural drawings for a RC
building

TUTORIAL QUESTIONS
i
What do you understand by limit state design in reinforced concrete structures?
ii
Itemise the basic steps to be followed according to BS8110 in the design of a simply supported reinforced
concrete beam.
iii
A reinforced concrete beam 300mm wide and 600mm deep is made to span 6000mm between the centres
of the supporting brick piers 300mm wide. The beam carries dead and imposed loads (excluding self weight)
of 25KN/m and 20KN/m respectively. Assuming the following materials strength: fcu = 30N/mm2 , fy
=
460N/mm2 and fyv = 250N/mm2 , design the bending and shear reinforcement of the beam for mild
exposure conditions taking the density of reinforced
concrete to be 24KN/m3.
iv
Using annotated sketches, distinguish between one-way and two-way spanning reinforced concrete
slabs.
v
What are the different types of reinforced concrete suspended floor slabs?
vi
What factors influence the choice of reinforced concrete suspended slab construction?.
vii
A reinforced concrete floor slab is subjected to an imposed load of 3.5KN/m2 and spans 4500mm between
reinforced concrete columns of 150mm thickness. Assuming the following material strengths: f cu = 35N/mm2
and fy = 460N/mm2, design the slab for mild exposure conditions taking the density of reinforced concrete to
be 24KNm3 .
viii
What are the different types of foundation you know? Using suitable sketches describes any two types of
foundation stating clearly where they can be used?
ix
State two conditions that might lead to foundation failure in reinforced concrete structures.
x
What factors influence the selection of foundation types?
xi
A 400mm square column carries a dead load (Gk) of 1050KN and imposed load (Qk) of 300KN. Given that
the safe load bearing capacity of the soil is 170KN/m2, design a square pad foundation to resist the loads with
the following material strengths: fcu = 35N/mm2 and fy = 460N/mm2. Assume a footing weight of
150KN.
xii
What are retaining walls and when are they recommended in structural design?
xiii
With annotated sketches, explain the types of retaining walls you know.
xiv
What do you understand by sheet piling and under what conditions is it recommended?
xv
What are the common structural failures of retaining walls?

Structural elements based on BS8110.
i. ALIGNMENT WITH COVENANT UNIVERSITY VISION/GOALS
In line with the vision of Covenant University to graduate total graduates who will be pace setters and
world changers in their various fields , this course is aimed at widening the scope of the understanding of
the students in the field of building structures which is essential in enhancing their relevance in the building
industry.
j. CONTEMPORARY ISSUES/INDUSTRY RELEVANCE
Architects are celebrated for their ideas that are successfully translated to built forms; this is made
possible when the creative ability of architect is reinforced by sound understanding of the structural
requirements of his designs. This course is very relevance in architecture as it further exposes the students to
the design of RC v structural elements that are commonly used in building construction to achieve
structural integrity.
