Analysis The Factors Influencing Seismic Performance Of Masonry Structure Based On The Numerical Simulation

In this paper,taking the dormitory building of a middle school in Sichuan as an example of earthquake resistance,combined with the relevant research results of some field investigation data and seismic analysis of the masonry structure,masonry structure wall failure under earthquake and failure characteristics,summed up the main factors affecting the seismic performance of masonry structures.With these factors as variables,using ABAQUS finite element software to establish different models,through comparative analysis of simulation results shows that influence of structure column and ring beam,the wall between the window and the window wall of the relationship and other factors on the masonry structure seismic performance.The main research of this paper can be summarized as follows:(1)analysis of the damage phenomenon of typical masonry structure,determine the factors affecting the seismic performance of masonry structures;analysis of relationship between constructional column and ring beam,wall and window between the wall of masonry structure seismic performance;through the comparative analysis of simulation results,verify the feasibility of the window wall with constructional column respectively.As the seismic line,in order to achieve the purpose of multi masonry fortification.(2)the large general software ABAQUS,Concrete Damaged Plasticity(Model)and the constitutive relation of various materials,failure criterion and parameter setting are introduced.Then through the design of a series of examples to determine the beam,constructional column and window wall between the window and the wall between the various factors on the seismic performance of masonry wall,combined with damage control thought,make the window wall before the window wall damage and become the first line of defense in the seismic,the destruction of structural column is the second line of defense multi-channel,masonry fortification target.(3)the establishment of the selected examples of simplified model using the finite element software ABAQUS,then the influence factors for variable conditions,model analysis and case comparison,through the comparison of the calculation of each structure model and analysis,beam and column settings can effectively improve the seismic performance of masonry structure strengthened.The whole masonry structure connection,make the destruction of the structure is more uniform.
