Mechanical Research Of Holing On Low Standard Masonry Structure Bearing Wall

With the development of the society and the increasing of people' s living standard, people have a high demand to the function of the building. It is important to reconstruct or reinforce the low standard buildings. Low standard buildings mainly refer to masonry building, thus it is urgent to study on the method of reconstruction. People come to concern the safety problem caused by the low standard and aging of the original building and weakening of the function due to long term building use; and with the cost of rebuilding the severe influence to the normal life order and environment and sustainable development, all these problems make most people concern the maintenance and modern rebuilding of the old buildings.In this paper, we analyze stress distribution of the hole of different size and shape at different part after holing on the bearing walls. In the paper calculate with the help of ANSYS, a finite element analysis software. And analyze the stress distribution and deformation of the wall under the vertical load and horizontal load. And come to a conclusion of the stress distribution due to the size of hole. We also analyze the influence of holing to the bearing capacity of the single wall. In order to derive precise conclusion, and reflect the stress situation really . In this article the element type of masonry and concrete adopt four-node element type, and steel and concrete adopt combined model, without regard to the slide; The thesis comes to some conclusions by contrast with different bearing capacity and deformation and analyze the influence of holing to the structure combined practical project. On the base of nonlinear calculation, thesis analyzes influence of the mechanism of wall and different parameter to bearing capacity, and try to achieve some applicable conclusion.
