Abstract: The aim of the research is to experimentally present the load-carrying capacities and failure modes of web expanded steel cellular beams and solid I-beams under the same load conditions. The experiments were conducted at full scale on non-composite beams. In this study, two tests were performed for web expanded cellular beams, and one test was conducted for solid I-beam, using IPE200 coded profiles. The spans of the beams were selected as 5.5 meters, and a point load was applied at the center of the upper flange. The design methods for the beams were based on the provisions of BS 5950.

Abstract: In the present scenario of the advanced industrial technology engineers and scientists have visualized and conceptualized many designs. The success of their designs and concepts is the materialization of their designs. Thus, the industry which gives shape to a theoretical design is a very potential and influential element in the technological development. The main objective of using jigs and fixtures in an industry is to achieve the Interchangeable Part Concept, and these are mainly used where production of goods is on large scale. The basic elements in the design of indexing type of drill jig is the component model, location, orientation and clamping. The scope of the research....

Abstract: In recent years jute geotextile used different areas of construction. It is relatively cheap and durable. It increases the bearing capability of soil that used in construction. It can be used in different purposes such as prevention of soil erosion,strengthening road subgrade etc. By using different length of jute fibre in pavement the strength of the subgrade can be increased. CBR value for different position of road has been studied by using different length of moulde of jute. In this review paper we studied about uses of jute to improve the strength of subgrade on road construction with the help of different kind of soil.Black Cotton soil,Murum soil and Mix soil are used to compare CBR value.

Abstract: Concrete is a construction material which is mainly used for its capacity to resist compression forces. However, when it is exposed to adverse condition of fire, the compressive strength degraded. Therefore, the study aimed at investigating the effect of time on compressive strength of concrete subjected to high temperature. Mix ratio of 1:2:4 and water cement ratio of 0.55 was used for the production of the test concrete cubes. Twenty-four concrete specimens were produced with three specimens for each time of 0, 1, 2, 3, 4, 5, 6, and 7 hours of fire exposure respectively. The test concrete cubes was produced by mixing the required weight of cement, aggregate and water, after which it was poured into an oiled mould of size 150mmx150mmx150mm and compacted in three......

Abstract: The purpose of this article is to provide an overview of the literature on ways for improving, configuring, and using various types of solar air heaters. To enhance SAHs' functionality, several theoretical and experimental studies have been conducted on them. On the absorber plate, many adjustments have been done. Using fins to increase the area for heat transmission is one of the key theories for improvement. Different fin styles, including longitudinal fins, corrugated fins, and fins linked to baffles, improved performance. The performance of SAHs was also improved by recycling. Additionally, it is discovered that intentionally roughened absorbers are employed to enhance.....
