<Ogirinal>Tensile Shear Creep Test of Steel-Balsa-Steel Sandwich Panel as Floor Deck (II) : Development of Simple Shear Creep Test Machine

Abstract

A simple shear creep test machine was proposed and creep test was made with ASTM standard shape specimens. Also comparative measuring method of shear deformation was discussed. The results obtained were as follows: 1) The test machine made as a prototype for tensile shear creep test was capable to transmit more than 1,300 kgf to the specimens so it would be suitable for test about 69% of shear strength (P_<max>=1,896 kgf), 2) The measuring method of shear deformation, which had the measurement points mounted on brass tips placed on loading plates edge, can be considered practical. Although the glue-line deformation between specimen and loading plates tested have been neglected. Prototype with accuracy and lower costs was achieved. Therefore, it is possible to extend the creep test period or to make simultaneous tests on many specimens when constructing several test machine.
