Experimental Study on Lateral Load Capacity of Bamboo RC Beam Column Joints Strengthened by Bamboo Mechanical Anchors

Abstract

In this paper, the prospective of bamboos which available abundantly especially in Indonesia as rebars and mechanical anchors are studied. And also the endurance of the bamboos mechanical anchors to withstand cyclic loading were observed. Nine classes of bamboos bar were evaluated: consist of 3 different anchors (0, 4 and 8 anchors) and 3 different compressive strength (19.19 MPa, 29.61 MPa and 37.96 MPa) means 3 × 3 parameters. The results show that the lateral load capacity increased significantly with the present of bamboo anchors specimens: 26.04 % for 4 anchors specimens (C2) and 25 % for the 8 anchors specimens (C3) compared to zero anchor specimens (C1). On the other hand, the compressive strength of concrete have no significant effects to the lateral load capacity. Overall it can be concluded that, bamboo can be used as mechanical anchorage to strengthen beam column joint.
