Paper Title
Study on replacement of Hot Rolled Angular Sections in Microwave Tower using Cold formed Sections
  Pallavi K Badwe

Historically, most Microwave towers have been fabricated from hot-rolled steel angles, but the availability of the thinner sections has become limited cold formed sections are readily available in the thinner sections and provide a alternative for more economical structures due to significant saving in weight. Cold formed members enable the engineer to design more cost effectively as it enables the use of various shapes and sizes as per the working conditions. This paper provides a general formulation for the design of cold formed sections other than hot rolled plain angles. To confirm the reliability of cold formed shapes for Microwave tower, a comparison of hot rolled steel angle microwave tower and cold formed angle microwave tower is presented. The analysis is carried out to examine the variable properties of a hot rolled steel section and of cold formed sections, compare the variation of Displacement (mm) at top for different tower and Comparison of Member Stress (N/mm2) at Bottom Leg. In this present study, the wind analysis of 4 legged angled section and cold formed section rooftop telecommunication tower has been studied along with wind analysis as per IS 875 (part 3) 1987. The analysis has been done on tower located on roof of host structure in STAAD software.

Keywords- Axial forces, Cold formed sections, Displacement, Hot-rolled steel angles, Microwave towers, Stress.
