Abstract:
During construction, the load on the slabs can be up to 2 to 3 times their self-weight, which can damage serviceability and structural safety of the slabs with early-age concrete. In the present study, an existing model to predict the load on slabs during construction was modified to account for the use of regular supports and temporary supports in the shoring system, considering construction step where temporary supports are removed. Additionally, the effective supporting area of the shore was introduced to account for the uneven distribution of shores, thereby improving the prediction of construction loads on slabs. To verify the accuracy of the modified model, loads on shores were measured at a wall-type residential building under construction in South Korea. For 2 stories, the loads on shores were measured and the measurement lasted for 45 days. The comparison between predicted and measured slab construction loads showed that the predicted construction load agreed with the measured construction load.
