ABSTRACT

The existing piloti buildings with supported reinforced concrete columns were very vulnerable to earthquake ground motions. Since piloti buildings are composed of the wall structure system in the upper part of the building and a relatively flexible beam-column system in the lower part of the building, piloti buildings are structurally vulnerable in the event of large transverse vibrations and cause collapses during an earthquake. This study aims to analyze the dynamic response behavior and capacity estimation of piloti buildings with a steel reinforced concrete column system on the first floor. To investigate the earthquake response of piloti buildings, the time history and pushover increment analyses are used to analyze the collapse pattern and capacity estimation of piloti buildings. The present piloti buildings constructed by reinforced concrete experienced most of the deformation on the first floor when an earthquake occurred, as shown in the yielding fracture of the columns on the first floor. From the results of this study, the piloti buildings supported by SRC reinforced concrete columns have enough strength and safety for a five-story building, but also have the required strength and safety for a ten-story building.
