Linear Analysis of Guyed Mast Subjected to （拉线式电杆受到的线性分析）

International Journal of Engineering Research and Applications (IJERA) ISSN: 2248-9622 Trends and Recent Advances in Civil Engineering (TRACE- 24th-25th January 2014) RESEARCH ARTICLE OPEN ACCESS Linear Analysis of Guyed Mast Subjected to Wind, Ice and Seismic Loading Bibitha K Eldhose*, Harinarayanan S**, S.Usha*** *PG Scholar, Email: bibz14@ **Professor, Email: harinarayanansiva@ *** Professor, Email: ushaushus11@ Department of Civil Engineering, Sree Narayana Gurukulam College of Engineering, Kerala, India ABSTRACT Masts are, tall structures designed to support antennas for telecommunication, broadcasting and television. They are among the tallest man-made structures. The telecommunication guyed mast towers are the kind of towers which are not self-supporting and requires external support of guys to stand. In the present work structure has been modeled with two node space truss element. Equivalent static wind loads has been calculated as per IS 875- 1987 (part3).This paper aims at investigating the, linear time history, structural non linearity of the structure subjected to the influence of wind, ice and earthquake loading. For the purpose of research activity, a 100m mast tower has been analyzed using SAP2000V14. Loads will be calculated and the structure will be modeled using SAP2000v14. Keywords - Guyed mast, linear analysis, wind load, ice load, natural frequencies. I. Introduction Guyed towers are almost exclusively used gust function variable along the height is proposed for communication purposes and structural reliability
