Abstract


Steel - concrete composite beam (hereinafter referred to as the composite beam) in the steel and concrete structures on the basis of the development of a new type of beam structure, usually of steel beams and reinforced concrete slab, shear connectors connected to form an overall flexural A structural member. The two materials together, according to the form of composite beams, the drawback can be avoided, give full play to the advantages of the two materials to form a high strength, stiffness, ductility good structure. China from the 1950s in transportation, metallurgy, electric power, coal and other system research and application of composite beams, made a series of important theoretical significance and practical value. However, all research and application of composite beams is limited to simply supported beam and continuous beam, composite frame beam is still rare. This paper presents a model of the structure of the composite frame beam through scientific experiments, finite element analysis and existing norms under the theoretical calculations, the three data to verify the safety and practicality of this composite frame beam structure model, and finally the study The application of the results to a residential steel construction. The full text is divided into seven chapters. Chapter 1, literature review, analysis of the characteristics of the composite beam pointed out that this article significance of the topic and research methods in the development of our country and the main research directions, steel - concrete composite frame beam structure model. Chapter 2 details the scientific experiments aim of the study, the design of the test model, test program design and arrangement of measuring points, and the test data processing and analysis, to provide a basis for in-depth study of the following. Chapter 3 describes the experimental model for finite element analysis: including the establishment of the approach in the finite element model, the choice of the finite element mesh and loading methods, and finally the calculation results were analyzed. Chapter 4 describes the use of a combination of theoretical calculations: including cross-section converter, internal force calculation, strain and displacement calculation Finally, the calculated results of the analysis and processing. Chapter 5 on the basis of the results of the first three chapters of a comparative analysis of the data, summarize the conclusions of experiments and calculations. Chapter 6 describes the composite frame beam applied to actual projects in structural analysis and related subjects approach for the application of research findings to accumulate experience. Chapter 7 summarizes the main conclusions of the work done in this article and get pointed out that the composite frame beam in the direction of future research.
