    Abstract: Road building in Ethiopia is increasingly in demand to meet medium and long terms development programs. Roads are constructed radiating from the capital city of the country in all direction. The objective of this research study is to evaluate the flexible pavement deflections with respect to pavement depth using Software along Jimma to Seka road se... Show More

    Abstract: Column plays very important role in reinforced concrete building as total load is transferred through column. When rectangular columns are used in structure, columns can protrude out of the walls and corners which reduce aesthetic view of structure. Concrete structures with specially shaped columns has been found out as a solution of this problem. ... Show More

    Abstract: Expansive soil refers to a particular type of soils – almost clayey soils in property - that expand as they absorb water and shrink when they dry out. The process of swelling generates pressures that can cause lifting, or heaving of structures whilst shrinkage process can cause differential settlement on civil structure. A large number of buildings... Show More

    Abstract: This paper presents the finite element results of a parametric investigation of the U-shaped box culvert of prefabricated reinforced concrete subject to loading conditions. It was included outer size span length 4.80m, rise of 4.80m, laying width 1.5m and 0.4m slab and wall thickness. Its components consisted of two symmetrical u-shaped structures ... Show More

    Abstract: The major lateral load of the high structures is the earthquake load. In the high rise buildings, the structural response increases exponentially in response to earthquake load. Therefore, the damping has significant function in design of Earthquake Resistant High Structures, which can decrease the response of the structure when exposed to lateral ... Show More
