Numerical Simulation Analysis Of Plywood Walls Reinforcement For Traditional Village Stone Masonry Structure

With the improvement of people's living standard,people's basic necessities of life are gradually improved.The taihang mountain area is rich in stone materials,and the traditional villages in the southeast are mainly built in stone materials.There are a lot of quality problems in stone masonry structures in this area.The Taihang mountain area is rich in stone materials,and the traditional villages in the southeast part of The Taihang mountain area mainly build houses with stone as the main building material,while there are many quality problems in the stone masonry structure houses in this area,For example,stone masonry structure design is unreasonable,construction operation is not standard,site section is not appropriate and so on.Field investigations revealed that many houses have become dangerous buildings,which seriously affectes people's normal living.The construction process of the structure is also an important factor affecting the structural safety,so it is urgent to design a reasonable reinforcement plan for the destruction of the housing structure in the area.Which is beneficial to prolong the service life of stone masonry structure and ensure the safety of people's life and property.It also has great significance for the protection of traditional Chinese villages.In view of the destruction of the stone masonry structure of the traditional village in the southeast of Taihang Mountains,which is the western village of Handan,Shexian County and Wuan,this paper puts forward the reinforcement method of plywood with different reinforcement ratio.For the purpose of not affecting the appearance of the structure,the interior of the wall is to be strengthened on the basis of the original structure.The structure is modeled and analyzed by ABAQUS finite element analysis software.In the unreinforced structural model,the paper points out the necessity of reinforcement and then strengthens the simulation of the structural model by comparing and analyzing the state of damage under different levels of seismic intensity.In the reinforcement model,this paper adopts the reinforced method of plywood wall reinforcement which is divided into four kinds according to the different reinforcement rate.In the model of strengthening structure,the advantages and disadvantages of the strengthening method are summarized by comparing the damage stress nephogram andthe drift angle between layers.Considering the factors such as reinforcement effect,economic level and the difficult degree of construction,the optimal reinforcement scheme is selected and recommended for the use of actual structural reinforcement.In this paper,the masonry structures of traditional villages in the west of Handan are studied as follows1.Conduct field research on the structure of stone structure,analyze its structure form,record its destruction form,and understand its construction technology.The main damage forms of the stone structure house are obtained and the causes of the destruction are analyzed.2.Based on ABAQUS numerical simulation analysis of stone masonry,the necessity of structural reinforcement and the effectiveness of the reinforcement method are obtained,and the optimal reinforcement scheme is finally selected.
