Studies On Mechanics Performance,Appraisal And Reinforcing Technique Of Bricky & Masonry Ancient Pagodas

China is a civilized archaic nation, and, as a part of Chinese culture, ancient pagoda holds an importance status in the develping histry of national architecture, but, now,it is not so satisfactory of the protection and study. By recordation, there are totol 10000 pagodas or so in the history, and now, only about 3000 pagodas are survival.further more, most of those 30 percent of the pagodas are in disrepair. Under the influence of earthquake, wind and cloud, thunder, plant on the pagoda etc, together with the man-made destroy, padogas always have a poor coherence, incline. In 1981, FAMEN temple padoga in FUFENG county broke down; In 1994, BAOBEN temple padoga rebuilt. The collapse of the two padoga brought hugeness losing, leaving behind limitless pity.Now, our nation just sets about studying and protecting the padoga, and has no well-rounded criterion of appraisal and reinforcing. With the rapid develping of the nation, we have the ability to identify and strethen the padoga. Under such a histry background, the paper studys the Mechanics performance, appraisal and reinforcing Technique of bricky & Masonry Ancient Pagoda.By large-scale finite element analysis sofeware, the paper calculated and analyzed padoga, and gave the three steady-going state: safe steady-going state, nonsafety steady-going state and breakage state. The paper analyzed the DAXIANG temple padoga detailedly.For the first time, the paper brings forward the concept of "temporal and zonation table of ancient pagoda material performance"and "compositive exponent method".To appraisal a padoga, we must known its material performance. But, as cultural relic, we cannot get the parameter by ruinous experimentation. The "temporal and zonation table of ancient pagoda material performance" solves the problem primely. The paper advice that we can collect ancient pagoda material performance as data-base in the project of maintain or rebiulting, andassign the data to the table by defence time and zonation for the further study."compositive exponent method" endows traditional experiential appraisal method determinate process and utilize compositive exponent y to appraise structure performance of ancient pagoda.By applying large-scale finite element analysis sofeware ANSYS in padoga analysis, we learn the padoga mechanics performance; The paper provide basal preparative work for criterion of appraisal and reinforcing; The paper dissertates retification technology combining some internal and overseas project.
