An Economic Instrument of Static Lateral Force Testing for Reinforced Concrete Column

Abstract

This research aims to invent an instrument of lateral force testing to study the behavior of reinforced concrete columns subjected to static lateral force. The sample columns of 20 cm x 20 cm in size and 150 cm in length designed for the concrete strength of 210 ksc at 28 days were tested. These columns were classified into two groups. The first were performed in accordance with the details of rebar and stirrup of the EIT 1007- 34 and the other were DPT 1301- 54. The test results show that the DPT 1301- 54 can be subjected around 2% - 9% maximum static lateral force more than the EIT1007- 34 and over 17- 35% increase in ductile index. Both of the columns showed contribution between flexural crack and shear crack as well.
