16841. The Effect Of Egg And Lime On The Compressive Strength Of Mortar
In Ethiopia there is a saying that tells buildings like Fasiledes castle of Gondar were built from materials that did not include cement. This saying describes the buildings as made from stones using lime mortar, consisting of sand, lime and egg parts, as a binder. This saying gave a motivation for...
16842. Prediction Of Compressive Strength Of Concrete Using Artificial Neural Network Fuzzy System Model And Thermodynamic Methods (a Comparative Study)
Utilization of concrete, as a material for building structures has been one of the major triumphs of mankind. Driven by increased standard of living and ever-rising population, the need for ‘better’ concrete is now the current trend. This in turn necessitates a representative measure...
16843. Dam Breach Analysis Inundation Map For Melka Wakena Dam
This study presented dam breach analysis & inundation map for Melka Wakena Dam. Melka Wakena Dam is an earth-rock fill dam with 42m height and 2000m long. The dam was designed to produce Hydropower of 153 MW. In this study, the Melka Wakena Dam breaching outflow hydrographs and downstream flood...
16844. Assessment Of The Effect Of Concrete Class Variation On Dynamic Response Of Framed Structures
Most of the time attention is not given by engineers when higher quality of concrete than therndesign requirements is used. And this indeed will increase the stiffness. In order to study thernbehavior and response to such increased stiffness, moment resisting planar structure has beenrnselected for...
16845. The Socio-economic Implication Of Network Marketing In Addis Ababa The Case Of Gold Quest International
The purpose of this study is to asses the general socia-economic implication of nelworkrnmarketing in Addis Ababa. Due to the youngness of the industry in the country, hardlyrnany studies have been made on this area; therefore, this study was initialed 10 fill Ihernknowledge gap that exisls in this...
16846. Assessment Of Earthquake Analysis Methods Of Intake Towers
Seismic analysis of an intake tower may be carried out using one or more methods from thernmethods Seismic Coefficient (SCM), Equivalent Lateral Force (ELFM), Response Spectrumrn(RSM) and Modal-Time history (MTHM) Methods. SCM, ELFM or RSM may produce responsernquantities with magnitudes bigger or...
16847. Assessment Of Ribbed Slab Constructions Framed Only In One Direction Against Lateral Load Excitations
Nowadays construction of buildings using ribbed slabs, with hollow blocks, is common from low to high seismic regions of Ethiopia. When investigating some of the buildings constructed and being constructed using such slabs, framing only in one direction is being practiced. In recent years, numbers...
16848. Assessment And Evaluation Of Slab Analysis And Design Practice In Ethiopia
The analysis and design of plate elements is too complex, for most cases therernis no closed form of solution for these are highly intermediate structures whichrnare full of assumptions, and uncertainty makes difficult for day to dayrnapplication and become uneconomical during design. To tackle...
16849. Fertility Preferences And Contraceptive Practices Among Currently Married Women In Jimma Raaree Woreda
Data on fertility preferences are useful as an indicator or general attitudesrntowards child bearing- and of the possible future course of fertility. The studyrnintends to explore the fertility intentions and contraceptive practices of currentlyrnmarried women in Jimma Raaree woreda. To this end a...
16850. Investigation On The Suitability Of Pumice And Scoria Aggregates In Ribbed-slab Constrution
This thesis presents the results of an investigation on the suitability of pumice and scoriarnaggregates in ribbed-slab construction. The aggregates were assessed for their utilization inrntopping and web construction of ribbed-slab. The suitability of using scoria as both fine andrncoarse...
16851. Investigation Of Alternative Design Forms Of Precast Beam For Low Cost Buildings
It should not be puzzling to have 55% of the condominium house lottery winners did not show up interest to sign and receive ‘their’ houses, which is claimed to be low cost and affordable to lower and middle class society, this figure will be larger in country side towns. This still...
16852. Modern Agricultural Input Adoption Under Production Risk The Case Of Fertilizer Application In Saesi Tsaeda-emba Woreda Eastern Zone Of Tigray Ethiopia
Empirical studies give evidence that farming is a risky activity, especially underrnrain fed agriculture characterized by erratic rainfall. In such conditions, productionrnrisks (crop fai/ure) arise mainly from uncertainties in climate, which isrnuncontrollable by farmers. Moreover, retum on modem...
16853. A Computer Program For Generating Design Charts Of L-shaped Short Columns On The Basis Of Ebcs 2 - 1995
In this thesis a program is developed to generate design charts of L-shaped reinforced concreterncolumn on the basis of EBCS-2, 1995. Design chart can be prepared for any cross-sectionalrndimension of columns with possible arrangements of reinforcement bars. The program will havernalso freedom for...
16854. Male Involvement In The Decision To Use Modem Family Planning Methods In Ethiopia The Case Of Meskan Wereda Snnpr
Shear behavior of beams was a major research area for over a century. However due to the fact that this behavior is dictated by different factors, researchers throughout the world have not come into a common understanding of a defined theory for predicting the shear behavior of beams. Spacing and...
16855. Effects Of Spacing And Configuration Of Web Reinforcement On Shear Behavior Of Reinforced Concrete Beams
Shear behavior of beams was a major research area for over a century. However due to the fact that this behavior is dictated by different factors, researchers throughout the world have not come into a common understanding of a defined theory for predicting the shear behavior of beams. Spacing and...
16856. Effects Of Masonry Infills On Reinforced Concrete Frame Buildings
In Ethiopia, most of the reinforced concrete buildings use hollow masonry infill walls as non-structural partition walls. Since they are used as a non-structural member, during design stage, their contribution to overall building behavior is not well known. Observations made after the earthquakes...
16857. Critical Comparative Feature Analysis Of Structural Software (sap2000 And Staad.pro) And The Nature Of Their Pirated Counterparts
Being in the mist of the computer era, it’s hard even to imagine the challenges faced in thernstructural world when such software did not exist. In this ‘time is money’ world reducing the timernfor analysis and design of a certain structure from months to seconds is a miraculous...
16858. Comparison Of Equivalent Frame Analysis Results With Finite Element Analysis Results For Flat Plate Slab Syste
Flat slabs can be analyzed by finite element method or equivalent frame method . Computer application of frame analysis method requires that each equivalent frame geometry, material characteristics and member properties be defined effectively. Two simplified methods exist, namely the effective beam...
16859. Seismic Behaviour Of Reinforced Concrete Buildings With Mass And Stiffness Irregularities
Many buildings in the present situation have irregular configurations both in plan and elevation due to architectural consideration. The main objective of this research is to study the seismic behaviour of building structures with mass and stiffness irregularities. This is done by quantifying the...
16860. Assessment Of The Effect Of Size Of Diaphragm Discontinuity (opening) On The Rigidity Of Diaphragm And Distribution Of Lateral Load To The Lateral Load Resisting Element
Earthquake - resistant structures are provided with lateral and vertical seismic force –rnresisting systems capable of transmitting inertial forces from the location of massesrnthroughout the structure to the foundations. Floor and roof diaphragms play a key role inrndistributing...
