Abstract2   In the construction of building, it is necessary to consider the reducement of construction period and the securement of enough work space during the construction. Especially, the importance of those increases during the construction of underground structure requiring the safety of sheeting by excavation work. In this manner, this paper investigates the structural safety of the building constructed by top-down method through analytical approach. Various types of earth pressure distribution were considered in the structural analysis of an example frame at each step of top-down construction. In addition, the variation of stress distribution due to the change of floor system to resist soil pressure in the excavation was evaluated. As an analytical result, the highest member force was found when the soil was medium plastered sand since with highest unit weight. Among three conditions of floor system, the case with both beam and slab was most effective to resist the soil pressure since the soil pressure acting to wale can be uniformly distributed to floor.
