EFFECT OF AGGREGATE TYPE ON MECHANICAL PROPERTIES OF CONCRETE AT ELEVATED TEMPERATURE

Zeleke, Aberham (2020-03-11)

Concrete is a material often used in the construction of high rise buildings, railroad and road tunnel constructions. There is an important problem influence of high temperatures on concrete that affects serviceability and ...
INVESTIGATION OF EFFECTIVE STIFFNESS OF REINFORCED CONCRETE FRAME MEMBERS SUBJECTED TO LATERAL LOAD

ALEFEW, ALEMAYEHU (2020-03-11)

Reinforced concrete structures are mostly subjected to loads causing the structure to displace laterally some amount of displacement called story drifts. Those loads may be mainly caused by earthquakes, wind or due to ...
Experimental Push-out Test and Finite Element Modeling of Locally Fabricated Channel Shear Connectors Embedded in Normal Strength Concrete Solid Slabs

Teshome, Ashenafi (2020-03-11)

The most important and frequently encountered combination of construction materials is steel and concrete. The use of composite structures in multistory buildings and high-way bridges becomes wide spread practice. Shear ...
Experimental Investigation on Compressive Strength of Concrete Made from Putty and Powder Lime as Partial Replacement of Cement

Yeshiber, Jember (2020-03-15)

Currently, developing countries are taking major steps for development of infrastructure and for fulfilling this aim, huge amount of concrete is required. Portland cement is a big source of environmental pollution. Therefore, ...
Numerical Investigation on the Effect of Reinforcement Shear Connectors in Load Capacity of Partially Encased Composite Beams

Semu, Tamirat (2020-03-15)

Side with frictional interaction between concrete and steel, shear connector plays crucial role in terms of slip protection ranging up to stress transfer though it. Even if variety of shear connectors are available, headed ...
Parametric study on minimum flexural steel ratio requirement for rectangular reinforced concrete beam through fracture mechanics modelling

Melku, Worku (2020-03-16)

The minimum flexural reinforcement required for concrete structure is required to change a brittle behavior of concrete structure to ductile behavior of RC structure. A minimum flexural reinforcement requirement is specified ...
COMPARISON OF SECOND ORDER EFFECT USING DIFFERENT BUILDING CODES AND FINITE ELEMENT ANALYSIS FOR CONCRETE FRAME ELEMENTS

WONDIMAGEGN, FETEHE (2020-03-17)

There are a number of methods and standards to compute the nonlinear static response of the frame, among them finite element softwares and building codes are most known methods. However there is a limited number of studies ...
EFFECTS OF FIRE ON RESPONSES OF MULTI-STOREY STEEL FRAMES

YENENEH, GIRMA (2020-03-17)

The effect of thermal stresses and deformations on the performance of a structure was generally not well treated in previous EBCS design codes. This study aims to investigate the responses of two-dimensional structural ...
PERFORMANCE EVALUATION OF PLANER SHEAR WALL WITH AND WITHOUT BOUNDARY ELEMENT IN MULTISTORY BUILDINGS UNDER HIGH SEISMIC LOAD

Teklay, Habtie (2020-03-17)

In medium and high rise building, reinforced concrete shear walls are a predominant lateral load resisting members in shear wall system and wall-frame lateral building systems under lateral loads. Constructions of medium ...
STRENGTHENING REINFORCED CONCRETE BEAMS USING TYRE STEEL FIBER BASED ENGINEERED CEMENTITIOUS COMPOSITES (ECC)

ALKASIM, HUSSIEN (2020-03-17)

There are many civil engineering infrastructures that cannot fulfill their intended purpose. Demand for higher load carrying capacity, material degradation, or change in use are the main reasons for such problems. In these ...
SOFTWARE DEVELOPMENT FOR ANALYSIS AND DESIGN OF SINGLE SPAN BOX-GIRDER REINFORCED CONCRETE BRIDGE SUPER-STRUCTURE

Getnet, Mastewal (2020-03-17)

Bridges are structures including supports erected over a depression or an obstruction for carrying traffic and other moving loads. Currently, the Ethiopian government has given special attention for road construction ...
A CRITICAL ASSESSMENT OF ANALYSIS AND DESIGN METHODS OF REINFORCED CONCRETE TWO-WAY SOLID SLABS

Demewez, Melkamu (2020-03-17)

Nowadays, several methods are available for the analysis of moments at the design section of reinforced concrete two-way slabs under gravity loads. In this investigation, it has been attempted to compare different analysis ...
DESIGN AID FOR FULLY & PARTIALLY ENCASED COMPOSITE COLUMNS SUBJECTED TO UNIAXIAL BENDING BASED ON RIGID PLASTIC APPROXIMATION

ESHETU, ALI (2020-03-17)

With the expansion of cities it is required to construct high storey buildings, bridges and other structures. Composite construction has been proven to be promising for multi storey buildings. As a result, composite columns ...
EFFECT OF TEMPERATURE ON CONCRETE STRENGTH

Nigussie, Tadiyos (2020-03-17)

Fire accident is one of the most frequently occurring accidents that could happen to any service structures in unexpected times. It requires a little source to be ignited but takes much more effort and cost to be controlled. ...
A comparative study on seismic and wind load response of tall RC building frame with various steel bracing arrangements

Sbhatu, Tesfamichael (2020-03-17)

Today, our country, Ethiopia needs to grow rapidly in terms of many aspects, for instance with respect to infrastructure. The population of the country is increasing day by day. Peoples are migrating from the neighboring ...
ASSESSMENT OF SEISMIC SEPARATION REQUIREMENT ON ADJACENT REINFORCED CONCRETE BUILDINGS

Dessie, Yilak (2020-03-17)

Seismic evaluations of adjacent regular and irregular reinforced concrete buildings are commonly adopted in Ethiopian design philosophy; this evaluation is performed to proportion cross sectional elements of buildings like ...
ASSESSMENT OF SEISMIC VULNERABILITY OF REINFORCED CONCRETE CONDOMINIUM BUILDINGS: A CASE STUDY OF SELECTED BUILDINGS CONSTRUCTED IN DESSIE

WORKU, AHMED (2020-03-19)

In most cases, buildings are constructed in Ethiopia without properly taking into account the impact of lateral loads due to earthquakes. Design of buildings to earthquakes is not given appropriate attention, even in ...
Relative Structural Cost Comparison of Gravity Load Resisting RC Multistory Frame Systems With and Without RC Wall around Elevators

Assrie, Amsalu (2020-03-19)

Now a days in our country it common using shear wall for construction of lift shaft. But Concrete shear walls or structural walls are often used in multistory buildings to resist lateral loads such as wind, seismic and ...
LIMITATION OF STATIC ANALYSIS ON IRREGULAR RC FRAME BUILDING WHERE IRREGULARITY IS DUE TO MASS AND STIFFNESS

Mihretu, Gezahegn (2020-03-19)

According to the new Ethiopian Standard Code ES EN 1998-1:2015, the Lateral Force Method (LFM) of analysis is allowed for building that are regular in plan and elevation. Building not regular in elevation can also be ...
