| In this paper,the corrective reinforcement project of the shear wall of the basement of the 5th building of Longjinyuan,Longjingyuan,Qujing City,introduces the existing building rectification technology,including the cause of the building deviation,the method of deviation correction,the control of the offset Standards,offset monitoring and corrective design steps and principles.The reason why the basement shear wall of the project is offset is that the basement design needs to be backfilled,and the shear wall can not be poured together with the first floor to form a stable whole body,but the template support strength is insufficient,resulting in the strengthening of the shear wall Offset.According to the data of these field detection and measurement,the axial force of the PKPM model was analyzed by using the total station,laser theodolite,steel ruler and other instruments.,The internal and external bending moment bearing capacity calculation,after analysis,proposed to increase the cross section of the correction method.That is,in the offset shear wall on one or both sides of the implanted steel mesh,and then support the template,and then pouring self-compacting concrete,in order to achieve the purpose of increasing cross-section correction.Using ANSYS finite element software to simulate the shear wall in the three states without deviation,offset and rectification,Derived shear wall stress cloud,steel stress cloud and shear wall displacement cloud,The stress and displacement of the shear wall in three states were compared and analyzed,and compared with the actual correction works.Finally,it summarizes the research results and shortcomings of the full text,and has some reference significance to the similar work in the construction of the correction work.. |
