The purpose of this study is to estimate axial force in shoring during construction of RC buildings using finite element analysis and to propose a simple method to estimate maximum force in reshoring. Cost for formwork takes substantial portion of concrete works in RC building construction. Efficient arrangement of shoring and reshoring leads to cost saving and safety of building. As the time dependent characteristics of concrete material, load transfer between slab and shoring mainly depends on concrete strength. slab thickness, construction period, number of shoring and reshoring. In this study, to figure out the effect of these parameters various conditions are simulated with simplified slab boundary conditions. Based on analysis result statistical program was used to propose an equation to estimate maximum force in shorings. To verify the applicability of the proposed equation three floor plans of constructed RC apartment buildings are analysed and compared with the calculation from proposed equation, showing very favorable result within engineering accuracy.
