Porch Collapse - High-rise Apartments

High-rise Apartments

High-rise apartment buildings are typically constructed from reinforced concrete. Many buildings have been designed with the concrete slab extending through the exterior walls to form balconies. Since they are relatively thin and unprotected from the weather, they are vulnerable to corrosion of reinforcing and potential collapse. Many buildings constructed in the 1950s and 1960s are undergoing repair or removal of such balcony structures at considerable cost.
