UTILIZATION OF COLD-FORMED STEEL (CFS) AS PURLIN FOR POWER PLANT STRUCTURES

摘要

One of the great advantages of cold-formed steel (CFS) is the immense flexibility that the material affords in forming cross-sections. This flexibility would seem to readily lend itself to optimization of member cross-section shapes. Cold formed sections also having the great flexibility of cross-sectional profiles and sizes available to structural steel designers. Whereas, the low strength-to-weight ratio of hot rolled steel members leads to increase in overall load on structure as compared with cold-formed steel sections which is having high strength-to-weight ratio. In this paper focus is given on utilization of cold formed section for purlins in comparison with traditionally used hot rolled sections in power plant structures. The cross-sectionalproperties and cost comparison is presented to understand the advantages of cold formed steel (CFS).
