Finite Element Analysis Of Masonry Walls Integral Strengthened By CFRP

The new structure technology of strengthening reinforced masonry wall with carbon fiber reinforced polymer (CFRP) has developed rapidly and used widely in resent years, especially in the field of strengthened with non-priestesses CFRP. The massive experimental research and theoretical analysis had been done at home and abroad, however, the further study on finite element simulations analysis is still in the process of conducting. As a new technology, whose applications and researching achievements are limited. In fact, it should be developed and promoted, so there is a lot of work to do in domestic academia. Based on the experiment results obtained lately by domestic academic scholars, a comparison is done with ANSYS calculation in this article, with an aim to confirm the finite element simulation analysis. Then it establishes three different finite element models to analog calculation and compares the analogue results. This article analyzes the performance indicators of masonry wall strengthened with priestesses CFRP. Therefore, the studies in this article had a strong sense of the theory and application in engineering on the practice of the application this new technology, strengthening reinforced masonry wall with CFRP. The main research works and conclusions are summarized as following:1. Firstly, it analog calculates model C-W6 (Corresponding this article model M1) used ANSYS based on literature [12]. It shows that the finite element analogue result and the examination result match well, especially before cracked. The finite element simulation is basically similar to actual destruction phenomenon. That proves that it is effective and reliable to apply ANSYS to simulate masonry wall's stress performance.2. Then this article simulates and calculates model M2, M3 and M4, through analyzing load—displacement relations curve, masonry wall 's and CFRP 's the stress distribution map and the crack distribution map, author got the rule of non-priestesses and priestesses CFRP reinforcement masonry wall. The analysis confirmed, with CFRP reinforced masonry wall, it would enhance wall's dehiscence load and delay dehiscence; it would restrain wall's displacement and reduce wall's internal stress value. It played a similar role as beam and column. Applying the priestesses CFRP reinforce masonry wall, its effect proves better.
