Nonlinear Numerical Simulation Of Prestressed Concrete And Reinforced Concrete Beam Based On ANSYS

Reinforced concrete and prestressed concrete structure applies in the civil engineering widely, ANSYS is the large-scale general FEA software whose function is most complete and whose application is most widespread. It has great significance that to enhance the design level and the quality of the entire civil engineering profession and to increase comprehensive economic benefit of project, if the civil engineers can make expertly numerical simulation to concrete structure with ANSYS.Applying the powerful function of ANSYS, this article carries on nonlinear numerical simulation of reinforced concrete and prestressed concrete beams, and compares with the test result. The article improves the method with ANSYS to analyze this kind of structure and obtains optimal analysis scheme. The main studies are following:1) The paper has summarized the reinforced concrete elementary theory as well as realizing method in the ANSYS.2) Used ANSYS, prestressed concretes and reinforced concrete rectangular beam, prestressed concrete hollow plate and prestressed concretes T-beam have been made the numerical simulation, and compared with experimental results. The paper has obtained optimal analysis scheme and summarized the problem to notice if analyzes this kind of structure with ANSYS.3) It is discussed the factor that influences prestressed concrete I-beams horizontal bending, and offer corresponding project measure to control the horizontal bending. It uses ANSYS to analyze the reason that the I-beams engender the "S" vibration in construction and the influence of tension order of prestressing steels to horizontal bending.
