Design Of Reinforced Concrete Multi Span Continuous Curved Beam

A curved beam is a beam with a cross section center and is not a straight beam.Due to its excellent mechanical performance and graceful streamline shape,curved beams have very important applications in civil buildings,industrial buildings,road bridges and curved beam structures in the aerospace field.For this reason,the research on the structure of the curved beam is becoming more and more importantThe main purpose of this paper is to summarize and summarize the design method of reinforced concrete multi span continuous curved beam.This design method is used to carry out the design of the bearing capacity of the reinforced concrete multi-span continuous curved beam of the auxiliary building in the North Plaza of Changsha Railway South Station.This article mainly carried out the following four aspects of work.This article will be mainly elaborated from the following four aspects.1.The elastic theory analysis of single span curved beam is carried out,and the stress and deformation laws of the single span curved beam are obtained at elastic stage.The finite element analysis method is used to analyze the whole process of single span curved beam and multi span continuous curved beam,and the distribution law of stress and strain is obtained.2-The design methods of reinforced concrete multi span continuous curved beams are summarized from the aspects of structural analysis,component design,structural requirements and construction drawing.Based on the above design method,the bearing capacity of reinforced concrete multi span continuous curved beam in the East Square of Changsha train south station is designed.3.Using the finite element method,the bearing capacity of the reinforced concrete multi-span continuous curved beam in the East Square of Changsha railway station is checked,and the influence of different parameters on the mechanical properties of the reinforced concrete multi-span continuous curved beam is analyzed.4.The work done in this paper is summarized and summarized,providing reference and advice for engineering practice.The shortcomings of this paper are pointed out,and the contents for further research are summarized.
