Abstract:
A practical computer program to determine the loads on the shoring system and supporting slabs during the construction of multistory concrete buildings is presented. The program was developed to assist contractors and construction engineers in evaluating the safety and economy of alternate procedures and develop rapid and safe construction schedules. The computer model is based on a two-dimensional slab-beam and column multibay frame similar to the equivalent frame concept described in ACI 318. The interaction of the continuously changing structure with the compressible shoring system as well as the time-dependent concrete properties of strength and stiffness are considered.
