Abstract

Profiled steel sheet dry board as a floor slab and it is a new innovation of composite slab structure in construction industry. It is consists of profiled steel sheet, dry board and screw as a connector. This study is to investigate the behavior of profiled steel sheet dry board (PSSDB) square panel. Plywood was chosen as dry board, SDP – 51 chosen as profiled steel sheet and self-drilling and self-tapping screw is used for connector. The component material was selected from the local market. This study consists of two part of analysis which is the theoretical analysis study for deflection of PSSDB and the experimental study for deflection of PSSDB at center point load mid span. Vibration test is also conducted in experimental study to investigate the damping effect of PSSDB. In theoretical analysis study, slip and strain at everywhere of connection between plywood and steel sheet is zero and assumed the plane section remains plane. This situation is knows as full interaction. The transformed section method was used to analyses PSSDB since it created from different material as raw material. The result of analysis pointed out that the deflection of PSSDB is increase when the load pointed on the PSSDB was increased. From experiment study, the first deflection was 1.86 mm at 1.55 kN. The maximum deflection was 47.83 mm at 21.7 kN. It was found that, damping ratio for the flooring system is 0.00045. A natural frequency, fn was 86 Hz and damped frequency was 85.9 Hz. The specimen stiffness was 26.78x 106 N/m. The value of critical damping coefficient and actual damping coefficient was respectively 99110.56 Ns/m and 44.60 Ns/m.
