Masonry Seismic Reinforcement In The Shear Capacity

In China,Earthquake-disaster happened frequently in recent years, Earthquake hazard Investigation showed that:Under the action of the earthquake-damage. Due to lack of strength to keep itself off the earthquake-damage,a large munber of the buildings collapsed.It brought great harm to people's lives and property. Evaluation for the old Buildings and rienforce their strength to ensure their safety was attached the government's great Attention. There are a lot of masonry buildings in China now,some of them didn't design correct or had been aged. Due to years of research and development, several mature seismic resistance of masonry reinforcement methods has beem Invented.But the task of reinforcing the old building's stength is very hard in our state now,so if we can find a new method for strengthening of masonry building,which is more simple and effectively will do great help to solve problems in current situation.The walls are the core components of the masonrybuilding,while it is also the major component to withstand the building's shear capacity.How to improve the shear capacity of the masonry wall shoud be the key of the rt for the masonry building.Base on the research of the common metheds of masonry building einforcemen,I proposed a new method named filling core and adding wall reinforcement. Compared with the common method,in the current situation this method has better applicability.The main work we have done:First. we have found out the major structural elements,which determined the effect of the new method. Second.through the orthogonal design,we can get some different working conditions.while using the FEM softwart Ansys we can the result of these working conditions.Third.rough analysis of the calculation results, we can find out the relationships between these major factors and strengthening effect.For example,how the reinforcement effect changing while the major factors were changing and how the factors work. Fouth.When the results analysis is completed,we can select the one which is the most suitable for the recent condition.Then,analysing the reinforced wall's shear capacity carefully to provide data basis for this methed's practical application in the future. Fifth.putting the filling core and adding wall reinforcement method into the program of northchina university of technology apartment 7 reinfocement to prove its applicability and feasibility.At last,I worked out the research summary,while brought out a number of issues yet to be analyse more deeply.
