A NONLINEAR NUMERICAL MODELING OF ACTIVE LATERAL EARTH PRESSURE DISTRIBUTION AND DISPLACEMENT PATTERN OF A RIGID CANTILEVER RETAINING WALL

SAMUEL, SIMENEH (2021-06)

In this study, the finite element method is used to investigate the variation and distribution nature of lateral earth pressure and displacement pattern behind a rigid cantilever wall. To provide resistance to overturning ...
CROP WATER PRODUCTIVITY ANALYSIS USING FAO-BASED (WaPOR) DATABASE, THE CASE OF KOGA IRRIGATION SCHEME, ETHIOPIA

Abiyu, Gebeyehu Anteneh (2021-06)

Agriculture is the mainstay of the Ethiopian economy in terms of income, employment and generation of export revenue. The development of irrigation and agricultural water management holds significant potential to improve ...
INVESTIGATING THE EFFECT OF VARYING CEMENT AND FINES CONTENT ON COMPRESSIVE AND TENSILE BEHAVIOR OF ROLLER COMPACTED CONCRETE PAVEMENTS

ABETU, ANTEHUNEGN ABEBE (2021-07-07)

The use of Roller Compacted Concrete Pavement (RCCP) is widely expanding throughout the world because of its benefits of reduced cement content, early opening to traffic, economic benefits and high speed of implementation ...
STRUCTURAL OPTIMIZATION OF SUPERSTRUCTURE PARAMETER OF EXTRADOSED CABLE STAYED BRIDGE USING GENETIC ALGORITHM, As A CASE STUDY ON ABAY RIVER BRIDGE

ABEBA, LAMESGIN SIMEGN (2021-08)

Weight of post-tensioning prestressing extradosed cable-stay bridge superstructure part formed from concrete, non-prestressing reinforcement, and prestressing reinforcement and stay cable tendon weight. Main load-carrying ...
Experimenting Study On The Engineering Properties of Expansive Soils Stabilized with Cement and Stereo Supremum Kuanthianum Wood Ash Targeting Performance As A High Way Subgrade Materials

Abay, Belay Tesfaye (2021-07)

Every structure must rest upon soil and the soil at that particular site should be satisfactory for the intended purpose. But unfortunately, nowadays findings show that such satisfactory soils are of rare in occurrence. ...
BEHAVOIR OF SETTLEMENT REDUCING STRUCTURALLY NON-CONNECTED PILES UNDER RAFT FOUNDATION

Fekadu, Wubetu Melese (2021-03)
Structural Instability Considerations on Paved Road Failure and Remedial Measures, (Case in Dejen to Lumame Road, (31km‟s) Ethiopia)

Eskezia, Alemu Mewahagn (2021-03)
PARAMETRIC STUDY OF PILED-RAFT FOUNDATION ONHOMOGENEOUS DRAINED STIFF CLAY SOIL USINGFINITE ELEMENT METHOD-ABAQUS SOFTWARE

TEZERA, TADILO (2020)

Recently, geotechnical engineers have started to design the piled foundations more optimized by allowing a part of the pressure to be transferred directly from the raft to the ground. Such a foundation, where the raft and ...
EFFECT OF EXPANSIVE SOIL ON LIGHT WEIGHT STRUCTURES OF GONDAR TOWN FROM CONSTRUCTION, GEOTECHNICAL AND STRUCTURAL PERSPECTIVE

BIYADGLIGN, SERAWIT (2020)

The amount of damage caused by expansive soils is alarming. Damages sustained by structures include distortion and cracking of pavements and on-grade floor slabs; cracks in grade beams, walls, and drilled shafts; jammed ...
Analysis of Piled Raft Foundation Subjected to Lateral and Vertical Loading using FLAC3D

Worku, Mulat (2020)

Due to the complex nature of the piled raft foundation, its realistic design relies on the more rigorous computer based methods using either finite element or finite difference based soft wares. This study develops a ...
EXPANSIVE SOIL GEOTECHNICAL PROPERTIES STABILIZED WITH PLASTIC POWDER AND LIME

Mulu, Mahider (2020)

Expansive Soil Geotechnical Properties Stabilized with Plastic Powder and Lime Expansive soil is considered defective due to the large volume change it undergoes for any moisture fluctuation. There are several engineering ...
