Subject :Seismic Respon se Analysis of The Silo Wall of Reinforced Concrete Silo Specialty : Structure Engineering Name : Yu Yang (Signature) Instructor: Su S anqing (Signature) ABSTRACT The silo as a equipme nt which stores the disperses material in agriculture, mining, building materials, chemical industry, electric power and other fields are widely used, and which has the such as structure simple,easy to operate, protection environment and reduced occpying l and area and so a such our much earthquake country,In -depth study of the seismic performance of the silo out the seismic response analysis of the silo structure of the earthquake is very necessary, And this research regarding guara ntees our country energy security strategy realization ,reduces the earthquake harm ,and guarantees the energy security effective supplies after the earthquake burst characteristics disaster have the extremely vital significance. In this article, it takes the practical engineering as the basis, with the l arge -scale finite software A nsys as the foundation, uses the finite element numerical simulation method,which considers the different stores -material operating mode, constucts to the reinforced concrete silo and carries on the static response analysis and earthquake response analysis. Taking the Solid 65 unit as the foundation, using surf 154 elements to simulate the different storage conditions, then can establish the reinforced concrete finite element analys is model, carry on the static finite element analysis to it , obtain the reinforced concrete large -squat -silo’s stress,strain and distortion distributed rule when the silo is full,and analyze this kind of structure’s stress -weak -
