Abstract
The design and analysis of a structural member requires the understanding of the possible loads that act on the system in the life span of the structure. For this reason, the stage of construction of precast joist is classified into two, initial stage and final stage. For each stage this study covers the ultimate resistance of the members and deflection control, to incorporate the limit state design requirements. Precast joist is used in one way ribbed slab and premature failure should be avoided in the life span of the precast joist. In this study, this is addressed by providing appropriate size of members for the initial stage and final stage, and by supporting the precast joist in the initial stage by temporary intermediate supports. A total of thirty two types of precast joist are modeled, analyzed and designed. Since up to three temporary intermediate supports are provided in the initial stage for each type of precast joist, the total number of models becomes one hundred twenty eight. The result of the study shows that all of them can survive the initial stage of construction if appropriate number of temporary intermediate support is provided. However, only half of them satisfy the ultimate state requirement in the final stage.
