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...

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...

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...

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...

Comparative Study On The Strength Of Lightweight Foamed Concrete Using Different Reagents (Lithofoam & Sodium Lauryl Sulphate)

ABSTRACTThis project presents the results of the investigation conducted on a lightweight foamed concrete using different reagents; Sodium Lauryl Sulphate (SLS) and Lithofoam, with a view to determining its potential as a construction material in Nigeria. The properties investigated on the foamed concrete having target density of 1800kg/m3 were: workability, bulk density and compressive strength. The foamed concretes produced using SLS were developed using a w/c ratio of 0.5 and a mix r...

MAINTENANCE OF URBAN INFRASTRUCTURES (A CASE STUDY OF ILORIN METROPOLIS)

ABSTRACTThis project “maintenance of urban infrastructures (a case study of Ilorin metropolis)” lays emphasis on the various Infrastructures such as Roads, Rail, Electricity, Water-Supply, Solid Waste Management Facilities, Drainage Facilities and Sewerage. The various magnitude and the facilities provided were looked upon; the various defects and possible remedies to some specific infrastructures were also looked at. The major data collection procedures were from the various infrastructu...

AN EMPIRICAL ASSESSMENT OF SUSTAINABILITY OF AN URBAN WATER SUPPLY SERVICE DELIVERY

ABSTRACTUrban population  is  rapidly  increasing  in  Ilorin  along  with  attendant  increased  water demand. The inadequacies of water supply services has forced the populace to depend on dug wells, boreholes, water tankers, street vendors etc. for their water needs. People spend hour’s daily carrying jerry can all around to collect and queue for water at the public water tap with high opportunity cost of time and intense economic wastage...

UNDRAINED SHEAR BEHAVIOR OF SOILS OCCURRING WITHIN NNAMDI AZIKIWE UNIVERSITY, AWKA

ABSTRACTDuring this research work, namely; the undrained shear behavior of soils within Nnamdi Azikiwe University, five different samples within the university compound were analyzed. Some laboratory test was carried out for classification and identification of their engineering properties, these tests include particle size distribution, Atterberg limit test, specific gravity, and free swell tests. Also, shear strength test (UU triaxial test) at different cell pressures and one-dimensional co...

Recycling and reuses of waste paper within Mapoly Community.

ABSTRACTThis work is an attempt at recycling and re-use of waste paper within Mapoly Community. Since the day it is invented till today, paper is a part of human life in various ways and it is gaining even more popularity as years go by. As the consumption of paper has been exploited. Recycling of paper has become vital since the demand for paper has increased and natural resources are being exploited.In this study, the quantity of solid waste generated within MAPOLY were assessed. Also, coll...
