Abstract

At this time, the architecture and design of the existing floor plan often changes according to the needs and tastes of the owner in accordance with the changing times. This research was conducted as precast concrete structures become even more important with the increase in man's desire to change the design of his home without spending enormous cost. This study aims to investigate the stiffness and study the behavior of precast concrete between monolith column with no connections and the column with connection. The connection used is dry joint using a plate and screw nut. The results obtained are the stiffness of the test specimen column with no connections is smaller than the test object column with connection. The modulus of elasticity of the column without a connection greater than the column with connection. Cracks that occurred in the test object columns without connection occurs faster than the test object columns with connection and both, flexural cracks occur first and then cracked in shear.

Abstract

DfD building system is a new approach in construction. Using DfD building system can reduce construction waste and reuse building components. This research examines the strength and behaviour of DfD column connections. Two types column connections were studied.The first connection employed H shaped steel elements bolted to the column while the second connection was bolt and plate connection. The behavior of columns with connections was compared to that of without connection. This study was carried out to investigate the strength, crack patterns, and failure mechanisms of precast concrete with dry joint on DfD column structure. All specimens were subject to normal force applied with an eccentricity of 67 mm. The test results indicate that both columns with connections were able to withstand design loads. This study also confirmed that the shear strength calculation of corbel based on SNI 03-2847-2002 section 13.9 was conservative to use as the value was still smaller than that obtained from this experiment.
