Test Research on Loading Safety and Space Finite Element Analysis of Existing Buildings Reconstruction
Existing buildings continue to use, maintenance or reconstruction, are required to appraisal and evaluation the security of structure[3], to ensure the in-service safety. Combing with a practical example of Better-life Commercial Chain Share Co,. Ltd in Changsha Red Star shop add billboard, have a visual inspection to the billboard support structure, investigate the use of the current situation and analyze the type of disease; using the finite element software MIDAS to establish finite element model of billboard and the main structure of its support, have a large number of numerical simulation; the results showed that the billboard design is reasonable, the flexural rigidity and carrying capacity of the main structure is acceptable, but the disease is more, endanger the use of safe, should carry out prevention and control processing.
