Safety Analysis of a Frame Building with Cracks Caused by Additional Equipments

Abstract:

The safety of a reinforced concrete frame building with cracks on a large area of its wall was investigated by using numerical analysis and field tests. The cracks were caused by the roof additional equipments. The layout of the roof additional equipments was measured to determine their additional loads. The width and depth of existing cracks was also measured. The static strength analysis based on the finite element technique is used to evaluate the influence of the additional loads on structural strength. The research results show the unreasonable supports of additional loads and the insufficient stiffness of secondary beams are the main reasons for causing cracks on the wall, and a reinforcement and repair thought for the building is proposed.
