Nonlinear Finite Element Analysis Of Brick Masonry Structure With Reinforced Concrete Constructional Column

Currently, brick masonry structure with reinforced concrete constructional column has been adopted widely, but the theoretical analysis and experimental research about eccentric compression is hardly found. This thesis focuses on the nonlinear finite element analysis of this kind of composite masonry structure. At the same time, this thesis is the theoretical analysis of one province-level scientific research project.After controlled nonlinear finite element function of ANSYS, this thesis founded the space model and simulated the behaviour of axial compression brick masonry structure. The result of ultimate load is tally with the result of experiment and is better than the previous result based on plane stress finite element. According to existing failure standard, this thesis uses the element table and parameter language APDL of ANSYS to determine the failure load and the result is tally with the result of experiment.This thesis simulated the behaviour of eccentric compression brick masonry structure with ANSYS and found the change law of compression bearing capacity. Further, this thesis has given the influencing coefficient of eccentric compression brick masonry structure, and it further can be used to found the perfect and practical formula. According to the calculation result of ANSYS, we can easily find the cracking or failure key point that can be used to become the control point in experiment.
