콘크리트 타설에 의한 편심재하를 고려한 동바리 측력 변화에 관한 연구

Abstract

In general, the form work is performed by the experience of engineer without exact analysis and design. And, in Concrete Standard Specification, the design load of shore is estimated as if the fresh concrete is placed simultaneously. But in fact the fresh concrete is placed step by step. When the eccentric load is bring the shores to induce tension force by the lever effect of near supports, therefore the shores could slide or collapse. The slab form work analysis considering eccentric loads by concrete placing time is performed and the axial forces of supports are observed.
