Probabilistic Construction Load Model for Multistory Reinforced-Concrete Buildings
Publication: Journal of Performance of Constructed Facilities
Volume 15, Issue 4
Abstract
This paper develops a probabilistic construction load process model for multistory reinforced-concrete building construction. This model considers loads causing peak structural actions on floor slabs for two widely used shoring procedures and includes probability distributions and temporal characteristics of slab self-weight, sustained construction live loads, “material stacking” loads, and “move-in” loads. Construction load statistics derived from Monte Carlo simulation show that the mean of maximum construction loads exceeds nominal (design) service (occupancy) loads whenever the nominal live-to-dead load ratio is less than approximately 1.0. A Type I extreme value distribution provided the best fit to the inferred distributions of construction live loads.
