  • Recently, structural damage and defect has occurred in the H-beam backfill installation part of Top-Down construction method. In order to secure structural safety and usability in the adjacent section of the backfilling method, It turns out that it is necessary to analyze by dividing into various cases. The H-beam backfill installation section is divided into the case of adding a vertical plate inside the slab, adding a shear stud, adding a reinforcing bar, changing the thickness of the pressure plate, and filling the H-beam backfill with mortar. Ansys modeling was performed and an appropriate solution was suggested by analysis.

  • Top-Down construction method is a method of connecting a beam to a column and using a strut to support earth retaining walls. This method has the advantage of reducing the process of underground construction by reducing the work of installation. Recently, there are a lot of cases of damage and defect occurring in H-beam backfill applied to Top-Down construction method and the concrete slab supporting H-beam backfill. For this, appropriate methods were suggested through finite element analysis of the position and installation form of the H-beam backfill.
