Numerical Simulation Under Reinforcing Masonry Buildings Of Menhanical Seismic Action Based

For a period of time in the future, masonry houses will still be the main structuralstyle in urban and rural construction. Since brick masonry buildings appeared in anearlier time, many brick masonry constructions just considered the gravity load whenthey were designed, but didn’t take seismic action into consideration,or with weakseismic action. However, seismic action is often the most unfavorable factor that causesthe damage and collapse of masonry buildings. Thus, the anti-seismic strengthening ofbrick masonry buildings makes prominent importance.Due to the attention paid to the carbon fiber composite received from strengtheningmasonry constructions with it and the superiority of the application of the finite-elementsoftware ANSYS to the mechanical property numerical modeling of construction, thispaper discusses adopting ANSYS finite-element software to respectively establish theoverall masonry houses model and eight different programs of carbon fiber strengtheningmodel. Through the comparison of failure mode, intensity and ultimate displacement ofeach model, the paper analyzes the influence of strengthening with carbon fiber on themechanical property of the houses, and reaches a conclusion of how to paste up thecarbon fiber cloth is the best for the anti-seismic effect of the brick masonry houses.The final comparison shows that strengthening the house with carbon fiber cancontrol the development of crack and distribute the cracks more evenly, to improve thehouses’anti-falling on side function and carrying capacity effectively; to paste upcombining with vertical and diagonal directions is the most useful for anti-seismic effectof the houses.
