Structure Monitoring and Long-Term Behavior Prediction of Wall-Piloti Structure

Abstract

In Korean residential building, wall – piloti structures have been frequently used in the ground floor. For cost-effective design, a new wall – piloti structure where the walls are directly connected with the columns without transfer girder was suggested in the previous study. In this study, the proposed structure was applied to actual residential building. To verify the structure safety, structural monitoring and long-term behavior prediction was carried out. Strain gauge and displacement meters was installed to measure the strain of re-bars and the deflection of slab. During the construction period, in all wall – piloti structures, compressive strain was less than the allowable strain and relative deflection of slab satisfied the serviceability criteria. Further, in the long-term behavior, the maximum vertical strains of the re-bar were less than allowable strain under the service load condition.
