Abstract: Based on some specific questions on strengthening design and construction of a sanitaria building, various strengthening methods were explored to deal with the bearing capacity deficiency of slab and beam for varying architectural function and the reinforcing bars deficiency of isolated foundations for addition storey. The structural and construction measurements are introduced. Some successful experience may be referred in similar structural strengthening design.
Keywords: structural strengthening; flexural strength of the support section of frame beams; post-embedding reinforcing bar; rigid foundation
