Discussion of the Stress State after Strengthening and Extending of a Hospital in Shanxi

Abstract:

At present, there exist more and more adding storey building in China, the research on the reconstruction project is also increasing. There are no corresponding technical specifications to constraint the concrete that add steel structure to the concrete structure, this is a blank area. A hospital floor in Shanxi is on the basis of the original eight-story reinforced concrete shear wall, using steel reinforced concrete to transition, adding five-story steel frame-buckling support structure. Using the large-scale finite element analysis software ANSYS, this paper analyzes the increasing cross-section method of reinforced concrete column to obtain the stress-strain situation of the old and the new combination surface and the stress-strain before and after the column reinforcement, proposes design measures to resist the shear on the old and the new combination surface working together to reduce the stress-strain hysteresis effect. The results provide a reference for similar project.
