The Research Of Reinforcement Is Base On The Analysis Of The Structural Damage In Earthquake

A Richter 8.0 earthquake attack the Wenchuan country in Sichuan Province of our country on May 12 14:28 pm. This earthquake caused a horribly casualties and property losses. Many buildings were badly damaged and even some buildings collapsed. So the analysis of the structural damage in earthquake and the research of reinforcement is very indispensable to the earthquake-resistance of buildings in our country. It can accumulate some practical experiences for alike constructions.This paper takes an electrolytic zinc industrial building in Shifang City as an example, introduces the repair reinforcement measures which are base on the analysis of the structural damage in earthquake. The content is about:1. This paper introduces the structural damage of an electrolytic zinc industrial building in Shifang City after the Wenchuan earthquake and analyzes the reason of earthquake damage. It establishes the basis for the structural analysis and the repair reinforcement measures.2. This paper introduces the structural calculation, nonlinear static analysis and plastoelastic structure dynamic analysis. Helped by the software PK, PUSH and EPDA, it appears that the above calculation results and deformation of the primary structure. Through analyzing the above calculation results, this paper makes judgment for the seismic performance and deformation of the primary structure and find the weak part for post-earthquake strengthening. It makes a good try to aseismic analysis of structural failure.3. This paper introduces the primary processes and core principle of post-earthquake and the widely-used methods to strengthen structure. After the structural analysis, this paper takes the design of lower column strengthenting with R.C as an example, introduces the practical application of structural failure ratio. This paper also introduces the repair and reinforcement measures of the structure and the calculation results of the strengthened structure.Analysis in this paper can be used for reference of seismic strengthening of alike projects, especially industrial factory building.
