Structural steel creates a stronger building with far less material and cross-section than concrete.
However, the previous studies shown strength loss of steel structures under fire loading. In practice, fire is
followed ...
Characterizing of engineering properties of soil plays a vital role for examining the suitability of the
soils for proposed project wo rk. This paper presents the field and laboratory test results of
subgrade soils ...
Construction materials management is the procedures, organizations, people, and

transport the associated information, ...
Providing an opening with the shear wall as the building's functional necessity such as door and
window openings can have a significant impact on its behavior. Therefore, this work is going to
investigate the effect ...
Expansive soils, commonly known as black cotton soils, are high volume change soils in which
montimorillonite is the principal clay mineral. These soils cause tremendous damages to
structures and, in this country; they ...
Geotechnical characteristics of the subgrade soils can affect the road quality and serviceability in
the construction of pavement, since all soils are not used as a subgrade material. The existing has
several failurities ...
Reinforced concrete (RC) columns are strong and durable, but can suffer structural damage
over time, such as cracking, spalling and corrosion. Various strengthening techniques have
been developed to address these issues, ...
Recent studies are focusing on ways of utilizing either industrial or agricultural wastes as
a source of raw materials for the construction industry around the world. This is used to
minimize the emission of CO2 during ...
Expansive soils are clayey soil that swells or shrinks, which increases in volume when in
contact with water, but decreases in volume when the water is removed. Therefore, these
soils are problematic soils when the ...
Infrastructure is a major sector that propels overall development of Ethiopian economy.
Construction of engineering structures on a weak or soft soil is considered as unsafe. The subgrade
and subbase of the soil has ...
Horizontal curves are usually considered as the critical points within the urban and rural road
network and the evaluation of their performance provides valuable understanding and useful
indication about the performance ...
Composite beams are structural members composed of two or more dissimilar materials
joined together to act as a unit. This thesis work studies the behavior and use of structural
steel and reinforced concrete combination ...
Bamboo fibers were used as a constituent material in the manufacturing of fiber concrete in this
study, the proportions of cement, sand, water, coarse aggregate, and bamboo fiber were
determined for C-30 concrete grade ...
Concrete suffers from several drawbacks due to the pollution associated with steel production,
high cost, low tensile strength, and low strain capacity that result in low resistance to cracks.
In addition, the production ...
Construction waste is a worldwide problem and is produced at most construction sites. Despite the
consensus that waste exists in the construction industry, the source of waste is different. As such,
this study aims to ...
The AEC (Architecture, Engineering and Construction) industry is one of the most fundamental
sectors for the economic growth of a country. It is also a very intricate sector that requires the
collaboration and ...
Although there are few pressurized irrigation projects launched in Ethiopia, there is hardly
ever any document of research works on the performance evaluation of the executed
pressurized irrigation systems. The irrigation ...
Gaps in provision of adequate water supply to rapidly growing urban population in developing country are increasing dramatically. Wolaiyta soddo Town is one of the towns faced with problem of water shortage as well as water ...
The pervasive influence of technology has transformed various features of our lives, including the area of education. Online examination has become a popular alternative to traditional paper-based tests, offering flexibility ...
The main objective of present research was to study the assessment of water supply
coverage, quality and performance of the supply schemes in Konso zone. The study
focuses on the assessment of drinking water coverage ...
