Finite Element Analysis of Mechanical Properties of New Assembled Steel Truss Simply Supported to Beam
This paper provides the design of a new type of assembled steel truss beam with serpentine web reinforcement instead of traditional hoop reinforcement.Based on a reasonable concrete plastic damage principal structure model,the force performance of this model is analyzed by finite element software ABAQUS.The different angles formed by the serpentine web reinforcement and the bottom longitudinal reinforcement are investigated,as well as the mechanical properties of the beam under the two loading forms.The load carrying capacity,deflection,crack development and economic efficiency of the conven-tional reinforced concrete simply supported beam and the new steel truss simply supported beam are com-pared and analyzed.The results show that compared with the traditional reinforced concrete beam,the new assembled steel truss beam has improved flexural and shear bearing capacity and the amount of steel rein-forcement is significantly reduced.Under the premise of ensuring structural safety and reliability,the new assembled steel truss beam structures to give full play to the advantages of reinforced concrete structure,saves construction cost and maximizes economic benefits.The results of the study can provide reference from the structural professional designers.
