 1. Abstract

This Project report is a Civil Engineering Integrated Design Project report on the Analysis
and Design Procedures of Reinforced Concrete Building Structure.
The Project is intended to design a Typical Ground + One (G + 1) Residential Reinforced
Concrete Building Structure.
Reinforced Concrete Structures are one of the most versatile forms of structures as
Reinforced Concrete has so many advantages as a Construction material.

The Best Tensile and Compressive Strength of Steel Reinforcement Bars and the best
Compressive Strength and durability achieved from Concrete, in addition relatively easy to
manufacture mold to almost any shape and size and relatively least maintenance cost makes
RC Structures to be widely accepted for almost all Building and other Construction works.

1.1 Purpose of Floors and Slab Types

Building Floor Purpose of Floor Slab Type

The Structural Design is based on the Rules and Regulations described on Ethiopian Building
Codes and Standards ES – EN 1998 – 2015

The Structure will be analyzed and designed based on the rules and regulations stated in the
specified Building Code and Ultimate Limit state approach will be followed in which the
structure shall be safe against failures associated with

o Flexure
o Shear
o Tension , Compression
o Torsion
o Sliding
o Overturning

Hence the Structure will be

o Safe
o Economical and
o Serviceable for the intended use and life period.
