STUDY OF SHEAR BOLT CONNECTOR STRENGTH TEST ON LIGHTWEIGHT CONCRETE COMPOSITE PANEL FEROFOAM TOWARDS PURE SHEAR USING PUSH OUT TEST METHOD

Abstract

The use of shear connectors in composite structural element is very important that a structure composite elements can work as a single unit in a resist shear forces. This study aims to examine the large load capacity and slip bolt shear connectors used in lightweight concrete composite panel ferofoam. Pure shear tests on shear connectors performed using the pushout test. Parameter variations speciefic testing is only on gravity of lightweight concrete foam. Shear connector is in the form of normal strength bolt, fu = 340 MPa diameter Ø10
mm are tied with the nut on ferofoam panel of 40 mm thickness, and 50 mm long embedded in lightweight concrete slab foam specimen push out. Cement Water Factor (CWF) ferofoam panels and lightweight concrete slab foam specimen push out is 0.4. Lightweight foam concrete ferofoam panel SG is 1.6 (f'c = 20 MPa) and the lightweight concrete slab foam push-out specimen is used variations of SG 1.0 (f'c = 5 MPa), 1.2 (f'c = 10 MPa) and 1.4 (f'c
= 12 MPa). In ferofoam panel is used reinforcement D13 mm as forming the framework of the panel with wiremesh layer as much as 4 layers. Specimens push out amount 3 pieces each SG with a total of 9 specimens. To control the compressive strength of lightweight foam concrete ferofoam panel and lightweight push-out concrete slab foam specimen is made 12 of
15 x 30 cm cylindrical specimens. The average experimental results of shear connectors bolts capacity on lightweight concrete foam of push out research SG 1.0; 1,2 and 1,4 respectively is 9.03 KN, 11.68 KN and 13.49 KN with a slip of 3.57 cm, 2.74 cm and 2.00 cm. Destruction on every variation of SG specimens represent a failure on the front bearing shear bolt connector on lightweight foam concrete slab push out specimen.
