The 2019 report from the Standing Committee on Structural Safety (SCOSS) found the collapse occurred with little warning and that a similar, near failure was reported in 2019 in a retail unit which incorporated the same type of concrete planks.. The report said the concrete planks in question - which were widely used in construction between the 1960s and 1980s - were much weaker than

Structural engineers use steel reinforcing bars known as rebar to make the columns stronger and more flexible. The rebar forms a cage inside the concrete, allowing it to crack and bend without crumbling. After the 1971 Sylmar earthquake, building codes required new concrete structures to have more of these steel supports.

Concrete can deteriorate for a variety of reasons, and concrete damage is often the result of a combination of factors. Chloride induced corrosion to reinforcement and other embedded metals is the leading cause of deterioration in concrete. When steel corrodes, the resulting rust occupies a greater volume than the steel.

However, a significant concern regarding reshoring lies in its safety and serviceability when shores are replaced while the construction load of the upper levels is applied. To investigate this concern and compare the construction load in shores and reshores, reinforced concrete (RC) beam-column joints at early ages were tested in the

Prestressed concrete. Although reinforced concrete is generally a better construction material than the ordinary stuff, it's still brittle and liable to crack: in tension, reinforced concrete can fail in spite of its steel reinforcement, letting water in, which then causes the concrete
