Abstract:
Determination of load distribution during construction is an important factor in assessing structural safety during the construction of reinforced concrete structures. A simplified method was developed in 1963 for determining the construction loads imposed on slabs and formwork. In 1985, a refined computer model for the analysis of slab-shore systems under construction loads was developed by Liu, Chen, and Bowman. The computer model has shown that the simplified method is adequate for practical use. The purpose of this paper is, first, to improve the two-dimensional computer model developed earlier by Liu, Chen, and Bowman by considering more construction parameters and procedures, and second, to compare this improved computer model with the simplified method. Furthermore, a simplified procedure to include the construction live load in the analysis of construction loads is proposed.
