Nonlinear Finite Element Analysis of Steel Fibre-reinforced Concrete Beam under Static Loading
Awoyera, P. O.
Published at Journal of Engineering Science and Technology , Volume 11 , Issue 12 , Published in 2016
A nonlinear finite element analysis of steel fibre-reinforced concrete beams subjected to static loading was explored using ADINA software. A predefined 3D model of concrete beam of dimension 100 mm×100 mm×500 mm was prepared using the smeared crack approach to fracture of concrete in the mode I; this model simulates a nonlinear response in tension. Stress redistribution was performed by the eq...
Influence of Electric Arc Furnace (EAF) Slag Aggregate Sizes on the Workability and Durability of Concrete
Awoyera, P. O., Adekeye, A. W., and Babalola, O. E.
Published at International Journal of Engineering and Technology , Volume 7 , Issue 3 , Pages 1049 - 1056 , Published in 2015
The construction industry has been identified as one of the largest consumer of nonrenewable resources. Meanwhile, the unused materials are continually disposed in landfills and dumpsites. As a result, adoption of industrial solid wastes for use as a construction material remains pertinent in the creation of a green environment. The present study focused on the influence of EAF steel slag aggre...
Challenges of Car Park Design in Nigeria
A. N. Ede, P. F. Adepoju, and P. O. Awoyera
Published at International Journal of Innovative Technology and Exploring Engineering , Volume 4 , Issue 10 , Pages 39-42 , Published in 2015
Problems of parking space in urban towns and in all places of large congregation is becoming a common issue around the world. Over the years engineers and architects have come up with a lot of solutions finding a way to create more parking spaces within minimum size of land by the design and construction of multi-storey car parks. This is line with the trend in modern cities all over the world...
Indigenous earth building construction technology in Ota, Nigeria
I. I. Akinwumi, P. O. Awoyera, O. O. Bello

Influence of Steel and Bamboo Fibres on Mechanical Properties of High Strength Concrete
Awoyera, P.O.; Ijalana, G.K.; Babalola, O.E.
Published at Journal of Materials and Environmental Science , Volume 6 , Issue 12 , Pages 3634-3642 , Published in 2015
This paper evaluated the influence of steel and bamboo fibres on high strength concrete. Samples of concrete cubes, beams and cylinders cast with varying proportions of steel and bamboo fibres were subjected to compression, flexural and splitting tensile strength tests respectively. A total of sixty three cubes of 100mm x 100mm x 100mm, fourteen beams of 100mm x 100mm x 500mm, and cylinders of...
Strength Characteristics of Concrete Beams Reinforced with Steel Bars of Equivalent
Adekeye, A.W.; Awoyera, P.O.
Published at Research Journal of Applied Sciences Engineering and Technology , Volume 11 , Issue 7 , Pages 765-769 , Published in 2015
Contractors occasionally substitute reinforcement bars during construction works, perhaps as a result of unavailability of the design-specified bars. As a result, this study have explored the basis, extent and the conditions for the mutual substitution of reinforcing bar groups of equivalent area but different bar diameters in reinforced concrete beams. A total of (20) concrete beams includi...
Numerical Modelling of Retrofitted Reinforced Concrete Building Frames
Afolayan, J. O.; Babalola, O. E.; Awoyera, P. O.; Adekeye, A. W.; Ishola, F. A.
Published at Research Journal of Applied Sciences Engineering and Technology , Volume 12 , Issue 2 , Pages 206-213 , Published in 2016
This study presents an overview and investigates the adequacy of the retrofit concept used in the reinforced concrete building frame of a distressed office building complex. The retrofit assessed consists of steel members welded together to form a steel frame with a reinforced concrete beam as base, acting as support for two floor slabs and roof truss of the building. Reinforced concrete bui...
Simulated Combined Earthquake and Dead Load Lateral Resistance Building Systems using Nigeria Seismic Data
Awoyera, P.O.; Ogundeji, J. F.; Aderonmu, P. A.
Published at Journal of materials and environmental science , Volume 7 , Issue 3 , Pages 781-789 , Published in 2016
This study investigated the effects of combined earthquake and dead load on a simulated lateral load resistance building systems. An eight-floor level steel building was modelled in SAP2000, and analysed using seismic information obtained from an earthquake which occurred at Abeokuta, Ogun State, Nigeria. The study was based on a selected magnitude of earthquake by considering the highest magni...
Parametric Measures for Design Workspace Adequacy of Selected Institutions in Nigeria
P. A. Aderonmu; P. O. Awoyera; S. A. Amole; O. M. Olofinnade; A. W. Adekeye
Published at ARPN Journal of Engineering and Applied Sciences , Volume 11 , Issue 3 , Pages 2105-2119 , Published in 2016
Architectural or Engineering design workspace is an arena where denominator activities takes place, however its adequacy has been neglected over the years. This study focused on parametric measures to ascertain design workspace adequacy of selected institutions in Nigeria. Questionnaires with multiple-choice and open-ended questions were administered to undergraduate and postgraduate archite...
