摘要：Steel has the highest strength-to-weight ratio of any construction material, and with new constructionmethods, steel buildings stay a popular choice for office and multifamily developers. When the modern world is givingso much importance for architecture which is mostly blended with flawless curves, need for curved structural elementssuch as curved beam, domes, bridges etc. are growing essential. Curved steel beams and girders are usually used in theconstruction of major buildings, modern bridges, highway ramps and interchanges, ships, and air space structures.Among a range of steel sections, use of I-beams is vast in industry for bridge girders & building girders. There is arising tendency to provide large service ducts and pipes beneath beams and girders. A solution regularly used is to giveopenings in the webs of the beams and girders so that the services could pass through the webs. Position, shape and sizeof the opening may differ according to the position, shape and size of the piping passing through webs, aestheticdemand etc. This study concentrates on the experimental and analytical parametric study of horizontally curved steel-Iwelded sections with web openings at various positions. The effect of shape and size of openings and other parameterssuch as effect of web slenderness and flange stiffness are also studied. For the study, finite element package ANSYS15.0 is used. When the use of curved sections is becoming important in the present world, study on their modifiedforms will gain popularity in the near future.
