Recovering the damaged industrialised building system beam flexural strength for re-use

Industrialized Building System (IBS) is a construction method where components are manufactured in factory or on-situ in a controlled and monitored environment, transported and assembled with minimum workforce. This system is widely used in the worlds. Upgrading of reinforced concrete structures may...
