Abstract:
The magnitude and time of application of construction loads in buildings constructed with formwork supported on previously cast floors have a significant effect on immediate and long-term deflections and on the service behavior of the structure. Construction loads, which usually exceed service loads, will cause long-term deflections greater than those predicted from service loads. A simplified method has been derived for calculating long-term deflections and deflections subsequent to the installation of finishes in multistory structures.*
