FEM Analysis Of The Reinforced Concrete Structure With Bonding Steel Plate

More and more scientific research and engineering technique persons think it important to repair and to reinforce the right current reinforced concrete structure. The purpose of repair and reinforcement is to improve intensity,hardness,lengthening,stability and enduring of the structures and components,to meet the need of security, to improve function of employment,to prolong the time of structures.The excellence of reinforcement with bonding steel plate is simple,shortcut, and it does not inflect the figuration of the structure, has little influence to production and life during the construction. Reinforcement with bonding steel plate is an advanced method that is widely applied in international area.At present, some correlative units in China and other countries have done large numbers of works at aspect of security analysis to reinforced concrete structure with or without reinforcement, but the means of analysis is always model examination. Although model examination is the main assistant means of theory study to reinforced concrete structures, it can relatively reflect the actual force state of the reinforced concrete structures or components, but due to the characteristics of the reinforced concrete structures, model examination has disadvantages: the workload of model facture and examination is heavy, the result of examination is discrete, expense of examination is expensive, it requires much manpower,many material resources ,many equipments and many fields. Along with the development of computer and the perfection of the finite element theory, applying FEM to study reinforced concrete structure with bonding steel plate which has become a study hotspot in domain of structure engineering, more and more scientific research and engineering technique persons think it important. Applying traditional analytical means to analyze the reinforced concrete structure with bonding steel plate can but resolve account of some very simple structures or components, it only being resolved by numerical analysis means for the complicated reinforced concretestructures with bonding steel plate. As an effective numerical analysis means, FEM has more and more important action in analysis of reinforced concrete structures with bonding steel plate. In this paper, having researched a means to establish finite element model of the reinforced concrete structures with bonding steel plate that using the existing finite element analysis software (ANSYS ) as the operation interface, having established finite element models of the reinforced concrete structures with bonding steel plate by this means, having done numerical analysis of reinforced concrete beam with or without bonding steel plate which is in constant load and in dynamic load, and having researched the reinforced concrete frame with or without bonding steel plate which is in all kinds of constant loads.
