Abstract

This paper presents the experimental study of six Double Skinned Hollow Concrete Filled steel Tubular (DSHCFT) columns consisting of PVC inner and mild Steel outer pipes in-filled with Self Compacting Concrete (SCC). The grade of SCC and the yield strength of steel used were M35 and 250 MPa respectively. The Columns were tested for axial load and Loaddeflection, Ultimate compressive strength were studied and reported. The experimental results are verified with European Code (EC4) and found as conservative. The PVC tube is found as a reasonably suitable alternate material for moderately loaded DSHCFT columns.

Keywords

Abstract

Objectives: To prevent accident and rear end collision in VANET, we propose to develop a method that will first create a cluster for preventing accident and rear collision in VANET Method/Statistical Analysis: Hence, to prevent accident and rear end collision in VANET, we propose to develop a scheme. First, with vehicles of same group moving in same road and direction, a cluster is formed. Among transmitted power and Contention Window (CW) size occasionally, every automobiles bounds an algorithm individually that’s adjusted. Findings: In urban areas, Traffic accidents occur because of sudden brakes, which demand a quick response from drivers. Therefore, a driver should be informed of the emergency events earlier. The proposed scheme applied each vehicle nodes in the network. Within the contention window metrics, the probability of collision between nearby vehicles is calculated and included which ensures the occurrence of appropriate modernize of transmission power and CW (Access Category) standards derived from the limited automobile density and the network circumstance correspondingly. The cluster with the header nodes maintain every unwanted or accident event and inform to every node to prevent accidents and rear end collision. This is significant to every sub cluster members of an SCH entity. An automobile can securely reject communication initiated from automobiles next to it. The recipient automobile can take; action derived from the primary and rejects the remaining replacement copies in case of redundancy.Applications/Improvements: The proposed scheme focused to enhance the delay, delivery ratio, energy and throughput compare to existing schemes.
