This type of structural design is mainly famous for multi-story construction as it reduces the thickness of the slab and overall height between the floors. Likewise, the columns that held up the slabs were created by pouring concrete around vertical stretches of rebar. Hence they need to be placed at a minimum depth. /Count 13 Specialists concurred that the concrete had not acquired sufficient strength to carry the construction loads applied during the construction process. 29 0 obj Timber piles were provided for the foundation of this project. Designed for classroom use, each case study contains a brief summary, lessons learned, and references to key sources. >> The investigation team revealed that the building collapsed due to the non-availability of an alternative load path when one portion of the external wall collapsed.
