Abstract:
Multistory reinforced concrete buildings are usually constructed by supporting newly cast slabs on a number of hardened floors. Construction loads and their distribution on the hardened floors depend primarily on the stripping and reshoring methods and secondarily on the load-deflection characteristics of the support floors, or the number of supporting floors. The simple sequential casting of fresh slabs and stripping of re shores produces construction loads which usually exceed the service loads and may approach the design (ultimate) strength of the structure. The attendant deflections and cracking are greater than predicted from service loads.
