OPTIMUM DESIGN OF WELDED PLATE GIRDER
ABSTRACTThe Project work presents an Optimum design of welded plate girder. A simply supported plate girder with span of 15meters was chosen for the case study. The girder was subjected to a self-weight of 50KN/m and concentrated loads of 1000KN at 5m and 10m from the left support. The plate girder was analysed to get the design moments and shear forces. An initial manual design was carried out for the plate girder in accordance with BS 5950-2000. From the design, initial section parame...
Dealing With Problems with Lime Stabilization Using Woven Geotextile under Soaked Conditions
Abstract: This paper examined the basic engineering and geotechnical properties of poor subgrade soils using woven geotextile to stabilize it and to also deal with the problem with lime under soaked conditions, it is intended at increasing the strength and mechanical properties of the soil even in extreme conditions. This is considered to be of great importance in civil engineering works as road structures need to be catered for during rainy season. Subgrade soils, it...
Assessment of Physicochemical and Bacteriological Parameters of Borehole Water of Lekki
Global health issues have awakened Engineers to looking into the causes of most health challenges and looking for ways to improve health status of humans. Research has shown that poor water contributes to most human health challenges. Water contributes perhaps most importantly to everything called existence. Virtually everything requires water. All living things depends on water to survive, which varies from one organism to another based on sizes, and many other factors, hence, need to provid...
General Design Procedures for Airport-Based Solar Photovoltaic Systems
A source of large surface areas for solar photovoltaic (PV) farms that has been largely overlooked in the 13,000 United States of America (U.S.) airports. This paper hopes to enable PV deployments in most airports by providing an approach to overcome the three primary challenges identified by the Federal Aviation Administration (FAA): (1) reflectivity and glare; (2) radar interference; and (3) physical penetration of airspace. First, these challenges and precautions that must be adhered to fo...
Scheffe’s Mathematical Model for Optimization of Compressive Strength of Periwinkle Shell Aggregate Concrete.
This project work aims at formulating Scheffe’s mathematical model which prescribes concrete mix ratios for a desired compressive strength of periwinkle shell aggregate concrete and obtaining the combination of water, cement, river sand and periwinkle shell which will produce the optimum strength. The model was formulated from first principle producing an equation with several unknown coefficients. These coefficients were determined by carrying out compressive strength tes...
Pultruded FRP-Concrete hybrid beams: characterization of shear connection behavior through static push-out tests
This paper discusses the recent investigation into the composite action of pultruded Fibre Reinforced Polymer (FRP) and concrete hybrid systems, under static push-out tests. The study sought to experimentally determine the characteristic load-slip behaviour of the FRP-concrete composites under varying shear stud arrangements and failures modes associated with the variations and the push-out load capacity. For the initial tests, three composite test spe...

ANALYSIS OF SANITATION AND WATERBORNE DISEASE OCCURRENCE IN ONDO STATE
ABSTRACTWaterborne diseases are linked to significant disease burden worldwide. Waterborne diarrhoea disease, for example, is responsible for tw o million deaths each year, with the majority occurring in children under five. Proper household water and sanitation can, however, increase &...
CAUSES OF CRACKS IN STRUCTURES
Building cracks are most common type of problem in any type of building. So, it is important to understand the cause and the measures to be taken for prevention. Though cracks in concrete cannot be prevented entirely but they can be controlled by using adequate material and technique of construction and considering design criteria. Due to some faulty steps during construction or some unavoidable reasons different type of cracks starts to appear on various structural and non-structural parts o...

To soil shear strength, plastic limit, liquid limit and the liquidity index of clay soil, undrained triaxial compression test, empirical correlations, and statistical analysis of geotechnical
Soils for engineering use are often classified based on properties relative to foundation support or as they might perform under pavements and in earthworks. Geotechnical classification systems today are designed to make it easy to equate field observations to estimates of engineering properties. As moisture content of a clay-like soil increases, it goes through four distinct states of consistency: solid, semi-solid, plastic, and liquid. Each stage is defined by significant changes in s...
Investigation of Bamboo as Possible Substitute for Concrete as Main Building Material in Nigeria
ABSTRACTBamboo is one of the oldest traditional materials used by mankind. They are the largest members of the grass family and are the fastest growing in the world. Bamboo is a substitute building material which is renewable, environment friendly and widely available as the wood resources are diminishing and restrictions are imposed on the felling of the natural forest trees. Due to its rapid growth and high yield, adaptability to most climatic conditions and due to its properties, bamb...
EXPERIMENTAL ANALYSIS ON THE ENGINEERING PROPERTIES OF SOIL A CASE STUDY OF POLYUNWANA MICROFINANCE BANK
ABSTRACTSoil is the ultimate foundation material which supports the structure. The proper functioning of the structure will, therefore, depend on the engineering properties of the underlying soil. The objectives of this research are to investigate the engineering properties of soils found in the site by conduction different types of laboratory tests. This research work is useful in providing necessary data or information that can be used in designing Civil Engineering structures in the site. ...
Enhancing concrete properties with the use of coconut (coir) fibers and admixture
AbstractIn countries where industrialization is on the rise there is a corresponding increase in wasteproduction resulting from industries which eventually upsetsthe environment and communityfor which they provide. While most of these waste generated are hazardous and should bemanaged, others could be put to appropriate use either directly or after been recycled. Mostagro-waste can be recycled and be used asraw materialsfor manufacturing various products.This research is designed to investiga...
STABILIZATION OF SILTY CLAY SOIL USING CEMENT AND SAW DUST ASH samson et al
ABSTRACT Soils containing large quantities of clay and silt are the most burdensome to the engineer. These soils exhibit marked changes in volume with changes in water content and consequently affect the function of any layer lain upon it due to its shrink and up heave behavior when used as a subgrade or a layer built of it. The test assesses the geotechnical characteristics of silty clay soil in order to increase the shear strength and decrease the compressibility of the soil, so t...
