Study And Analysis Of Detection And Seismic Strengthening Of Existing Brick Masonry Structure

The industry of maintenance,reinforcement and reconstruction for the existing building structure is one of the most popular industries in the nine major industries of twenty-first century. Following the requirement of the maintenance and reconstruction for the existing building and the development of modern technology,as a new science the detectionand strengthening for the existing building structure is formed quickly and developed rapidly.on the basis of the development of the detection and reinforcing in this decade and referring to mang engineering applications,the theory of the detection and strengthening of the existing brick masonry structure is deeply discussed. The highlights of the dissertation are as followed:(1) Now the dimension of sampling size is not perfect in detection norms,based on the exectud outcome and the sampling theory, the defining of sampling size is deeply discussed,the influence factors of sampling size is analysied.it is inevitable that the existing abnormal value. Statistical outlier test is used to verify the outlier in the data in order to improving the reliability of the data. it may be referenced by technical staff in detection.(2) As a basis of the appraiser and strengthening,the accuracy of the detection is very important.the scope of the detection and the contents of the detection are discussed,associated with the project,the detection process is detailed discussed. the estimation of concrete strength is intensive illuminated,a new method of data analysis is put forward.the project proves that it is feasible.how to give the rational estimation of the populations under the circumstance small samples. conjugate distributions and bayes estimation for the normal distribution are introduced.(4) the seismic strengthening is the important integrant of State Aseismic and Against Natural Calamities.associated with the project ,the way and the contents of the seismic strengthening of the existing brick masonry are introduced , at the same time the seismic ability of the building are illuminated , the reinforcement proposal of the building is given out.
