Analysis On The Structural Systems Of Composite Beam And Continous Compound Spiral Hoop Reinforced Conrete Column

The structural systems of composite beam and continous compound spiral hoopreinforced concrete column have the advantage of better seismic behavior, faster constructionprogress, materials saving. At the same time, producing continuous composite stirrups inmodern machinery provides the conditions for the development of the structure in China. Thestructure is bound to have good prospects for development in China.However, the current research and application of the structural systems of compositebeam and continous compound spiral hoop reinforced conrete column in China is in itsinfancy, and our specification don’t make a detailed description of design and calculationabout the structure. Therefore, it’s urgent need to study on design of composite beams andcontinuous composite spiral hoop concrete column to provide guidance for the structuraldesign and thus promote the use of the structure in the actual projects.This article summarizes the existing research on confined concrete at home and abroad,focusing on research of stirrups constraints concrete. On the basis, the relationship betweenthe stirrup characteristic value and compressive strength of continuous compound spiral hoopconcrete column is explored in this paper. Combined with domestic norms, this papersummarizes structural measures of continuous compound spiral stirrups concrete column,such as encryption stirrups, axial compression ratio and minimum stirrup characteristic value.Combined with existing domestic and international design codes, the article analyzeseffective flange width of composite beam and gives a calculation formula. It studies two kindsof analysis methods that flexible analysis and plastic analysis about flexural capacity ofcomposite beam and deduces a calculation formula of moment modulation coefficient. It alsostudies on design of composite beam with web openings.Detailed comparison of beam-through-type joint and column-through-type joint in forceperformance, construction techniques and so on, this article proposes a new type of RCS joint,improving beam-whole-through-type joint. It also gives advice to design and calculate shearcapacity of the RCS joint.With a project, the article studies the structural systems of composite beam and continouscompound spiral hoop reinforced concrete column and ordinary reinforced concrete framestructure in force performance, material consumption and so on. The results show that thestructural systems of composite beam and continous compound spiral hoop reinforcedconcrete column is better than ordinary reinforced concrete column frame structure. Therefore, we should promote the use of the structural systems of composite beam and continouscompound spiral hoop reinforced concrete column in the actual project.
