Abstract |
During construction of reinforced concrete structures, it is important to secure the safety of form-shore structure system. But structural engineers haven't been concerned about the safety of form-shore system during construction. Moreover, engineers and crews have faced many difficulties during construction because of the lack of guidelines and codes about form-shore system. In the actual construction site, the distribution and transmission of concrete loads which are placed on the form-shore systems are different from expected results because of complexity which occur during construction. The purpose of this paper is to study an axial force variation of shores due to concrete placement paths and load redistribution through experiment and structural analysis. The neoMAX-3D program is used for the structural analysis and the experimental results are compared with the analytic results. |
