Design & Development of Thermal Management of LED Street Light
Authors: Arth Patel, Akash Patel, Shakti Thakkar
Abstract
Use of LED based lighting product has been increased after 2006 (invention of white LED). There are numbers of research are going on for improvement in energy efficient LED based lighting by reduce junction temperature. Hence, it is required to develop efficient thermal management. For good thermal management it is needed that the thermal resistance of luminaire body should be as low as possible. This can be achieving by increasing the area of heat dissipation, which increase the size of luminaire body. This is not the desired condition. Hence it is required to find other way like mechanical design, heat sink material, mounting arrangement and driver current etc, by which one can achieve energy efficient thermal management. That work will include the detail study of LED, LED luminaire, searching of energy efficient material for design and Development and also Simulate efficient thermal management for LED based street Light.

COMPARATIVE STUDY ON COLLAPSE RESISTANCE OF RC BUILDING STRUCTURE HAVING PLAN IRREGULARITY
Authors: Bhavik Patel, Dr. Bharat. J. Shah
Abstract
In this article, an attempt has been made to study the assessment of collapse resistance of RC building structures having plan irregularity. Moment resisting frame have been considered for the collapse analysis and the same have been designed as per IS:456-2000, IS:1893-2016 & IS:13920-2016. The Structure have been design using linear static method as mentioned in IS codes, and the same have been checked against collapse resistance using nonlinear static pushdown analysis. The models considered for studied are rectangular & L-shape in the plan. Typical three buildings are considered namely G+4 storey, G+7 storey & G+10 storey. For both rectangular and L-shape building, floor plate area has been maintaining same for better comparison on collapse load carrying capacity. Nonlinear behaviour of the elements is modelled using plastic hinges based on moment-curvature relationship as described in ASCE-41/FEMA 356 guidelines. The structure is pushed down monotonically to monitored failure behaviour. Four columns removal are considered for collapse assessment, potentially critical as defined in GSA guidelines. Column removal are considered on a time only, and the response of structure have been noted by pushdown curves..
