Abstract
With the development trend of industrialization of building, truss structure is more and more widely used as a simple force structure in engineering applications because of its advantages of light weight, large span, low steel consumption and so on. The key to improve the overall stability, ultimate bearing capacity and seismic performance is to make use of the mechanical advantages of the new materials. This paper expounds the characteristics of concrete-filled steel tubular trusses, introduces its application in bridge engineering and building roof structure, and systematically summarizes the design theories and research results in the field of truss at home and abroad. The feasibility of a new epoxy resin concrete material in the application of concrete-filled steel tubular truss is discussed, and further research work is expected.
