nalysis and Parametric Study of Load-displacement Behavior of Large Group Pile Under Lateral Loading

Bayissa, Waltaji (Addis Ababa University, 2019-04-14)

Investigating the effects of lateral loads in design of foundation is important as compared to axial loads, although it gets normally less consideration in the usual practice. This study investigates the behavior of group ...
Numerical Investigation on the Behaviour of Laterally Loaded Pile Embedded in Layered Soils of Addis Ababa

Fenta, Nebiyou (2019-10)

A three-dimensional finite element technique was used to analyze behaviour of laterally loaded single pile subjected to pure static lateral load. The main objective of this study is to assess the influence of the pile ...
Optimized Use of Settlement Reducing Piles for Raft Foundation on Clay Soil

Dawit, Baye (Addis Ababa University, 2020-10-11)

In this study, a concept of using piles for settlement control has been examined through a Finite Element modeling technique. A raft alone may be adequate in terms of bearing capacity but predicted settlement may exceed ...
Optimum Design of Highway Cut Slopes in some Selected Soils found in Ethiopia

Asfaw, Hussien (Addis Ababa University, 2010-12)

This thesis presents the safe and economical highway cut slope design in some selected soils found in Ethiopia. The preparation of the standard has been carried out by determining the soil shear strength parameters in the ...
Parametric Study on Analysis and Design of Permanently Anchored Secant Pile Wall for Earthquake Loading

Emmanuel, Julius (Addis Ababa University, 2017-03)

Due to space limitations in urban areas, deep excavation in to the ground has become a common practice worldwide. Among the conventional retaining support systems, this study is focused on secant pile walls. The secant ...
Performance of Unconventional Soil Stabilizers in Stabilization of Substandard Materials for Road Subgrade & Subbase

Ashuro, Tesfahun (Addis Ababa University, 2010-06)

Road connectivity is one of the key components for development, as it promotes access to economic and social services, generating increased income and employment. However, the construction of such economically vital ...
The Potential Use of Cinder as a Sub base Material When Blended with Fine Grained Soil (The Case of Durame Intercity Road Project

Ermias, Lulu (Addis Ababa University, 2019-11)

Soil stabilization is the process of improving the engineering properties of the soil and thus making it more stable. In the process of soil stabilization and modification or soil strengthening, emphasis is given for ...
The Potential Use of Cinder Gravel as A Base Course Material When Stabilized by Volcanic Ash and Lime (The Case of Metehara Area)

Zerai, Hadera (2015-10)

This study has been carried out in order to determine the optimum blending proportion of cinder gravel with volcanic ash and lime. In this regard, an investigation into the improvement of the natural cinder gravel by ...
Predicting the value of CBR from DCP for Addis Ababa Red clay

Ermias, Genye (Addis Ababa University, 2014-11)

The research attempts to introduce the Dynamic cone penetration (DCP) to replace CBR test in preliminary design stage. DCP is a simple test device, portable and easy to operate and a repeated test can be conducted as much ...
Prediction of Swelling Behavior of Addis Ababa Expansive Soil Using Simple Mathematical Model

Assefa, Eleyas (Addis Ababa University, 2012)

Damage due to soil swelling is very noticeable in wide spectrum of structures such as roads, buildings, canal linings, landfill liners, etc. To evaluate severity of swelling and to design for the best and most economical ...
Reinforced Earth Retaining Wall Design Using Reinforcement Steel With Gabion Facing

Tadesse, Tilahun (Addis Ababa University, 2006-10)

This paper presents reinforced earth model retaining wall made of reinforcement steel and gabion facing. Four model reinforced earth retaining wall were designed and constructed at selected site in Technology Faculty ...
Relation between Shrinkage Index and Swelling Pressure for Expansive Soil found in Addis Ababa

Jemal, Yasin (Addis Ababa University, 2011-12)

This research is inspired by the PhD thesis work of H. B. Nagaraj from Indian Institute of Science titled “Prediction of Engineering Properties of Fine Grained Soils from their Index Properties”. The PhD thesis indicated ...
Relationships between Plastic Index with Linear, Volumetric Shrinkage for Tendaho Road Project

Tesfaye, Mebratu (Addis Ababa University, 2019-03)

Currently there is a belief within the geotechnical Engineering Profession that there is not strong form of correlation between plastic index with linear, volumetric shrinkages properties for a soil [16]. This project would ...
Reporting of Test Data in Soil Laboratories for Road Proj Lab Aid Software Development for Performing, Analyzing and Ects

Berhanu, Fasil (Addis Ababa University, 2015)
Seismic Evaluation Using Non-Linear Time History Analysis

Netsanet, Teferra (AAU, 2018-07)

A building subjected to earthquake is expected to show inelastic behavior that the deformation in a member does not remain proportional to the internal force. A non-linear analysis accounts for the inelastic response. ...
Shear Modulus and Damping Ratio of Dry Koka Sand Using Cyclic Simple Shear Test

Girmachew, Yimer (Addis Ababa University, 2010-06)

The nature and distribution of earthquake damage is strongly influenced by the response of soils to cyclic loading, and the behavior of soils subjected to dynamic loading is influenced by dynamic soil properties. The ...
Shear Modulus and Damping Ratio Values of Soils Commonly Found in Hawassa

Ayalew, Gashaw (Addis Ababa University, 2012-06)

The nature and distribution of earthquake damage is strongly influenced by the response of soils to cyclic loading. Design of geotechnical engineering problems that involve dynamic loading of soils and soil-structure ...
Shear Strength Characteristics of Soils in Adama Town

Kassahun, Genet (Addis Ababa University, 2013-12)

Adama is one of the most developing towns in Ethiopia as a conference and a tourist resort center. A lot of construction work is constructed at present. It is also expected that much more construction is going to be done ...
