Behaviour of High Performance Fibre Reinforced Concrete Beam under Cyclic Loading



N.Parthasarathi,K.S.Satyanarayanan, V.Tamilarasu, M.Prakash



This paper explores the cyclic behaviour of the high performance
concrete and also describes influence of steel fibres in the HPC beams.
The high performance concrete mix with M60 grade was designed using ACI
2411.4R. An experimental investigation of the behaviour of HPC beams
reinforced with normal steel bars and steel fibres under cyclic loading
is tested and the results are presented in this paper. In this study 9
R.C.C beams were casted using high performance concrete, which includes
control beam that consists of normal mix without steel fibres. And
remains R.C.C beams consists of two different volume fractions (0.75%
and 1%) of steel fibres with two different aspect ratio ( 60 and 50).
All beams were tested under full cyclic load to establish
load-deflection curve and the results were evaluated. The results also
show that inclusion of steel fibres intensify the ductility, Stiffness
and residual strength. Inclusion of steel fibres has proven to resist
the stiffness degradation after applying four number of cyclic loading
on the HPC beam.Studies revealed that, the use of fibres in concrete for
the construction purpose to decrease the cracks as well as strength.

The Ecological Impacts of Light Pollution at Night-time a Mechanistic Appraisal

The Ecological Impacts of Light Pollution at Night-time a Mechanistic Appraisal Abdullahi MG, Roslan U, Kamarudin M. K. A. Artificial light at night and its negative consequences are of great interest in the fields of Ecology, Human Geography Astronomy, and Human Health. Most of the studies to date concentrated on the influences of light pollution has on our ability to view the night sky, on biodiversity, and ecosystems. Though, in recent years, with the use of new technologies sensors, which provide accurate information for determining of night lights at the area, most consideration were given for estimating artificial light at night within the urban areas. In this study, urban night lights within the cities of Nigeria was evaluated by monitoring data from the ground measurements using Sky Quality Meter (SQM-LU-DL) devices. Besides, the SQM was used at the zenith (upward direction) for maximum evaluating of artificial light at the sites. Differences in night sky bri...

Studying the tendency of citizens to participate in the protection and development of land scape in Tehran

Studying the tendency of citizens to participate in the protection and development of land scape in Tehran Shadi Maleki, Abbas Mafi, Seyedeh Mahsa Hosseini Today, as an essential part and parcel of urban landscape that they play a major role in metabolism and create a lack of serious damage to urban life. This study performed to investigate the willingness of citizens to participate in activities to protect and develop landscapeof Tehran district 4. The research was descriptive and correlation method that is used for collecting information. The statistical population consisted of district 4 of Tehran. The sample size was determined 230 by using Cochrane method. A questionnaire was used to collect data. According to the research, 63.04 percent of citizens showed participation in a high level. Among the variables investigated how citizen participation in conservation and development of landscape, effective strategies to motivate citizens to participate,the reasons for la...

Land Use Land Cover Change Detection by Using Remote Sensing Data in Akaki River Basin

Land Use Land Cover Change Detection by Using Remote Sensing Data in Akaki River Basin Adimasu Woldesenbet Worako   Land use land cover change (LULCC) is the result of the long time process of natural and anthropogenic activities that has been practiced on the land. GIS and remote sensing are the best tools that support to generate the relevant land use/cover change in the basin. This study was conducted in the Akaki River basin to detect land use land cover changes within the 30 years period (1985-2015) by using landsat imagery data acquired from the GCF. Supervised maximum likelihood algorithm classification were deployed to classify land use/cover into four prominent land use groups and data’s were processed by using ERDAS imagine 2014 and ArcGIS10.1 software. In the basin dominant LULC was agricultural land use which accounts around 56.28% and the second largest is built-up area by 31.51% and the rest, forest(11.9%) and water body(0.31%) coverage were takes t...
