In peripheral,<br>edge beams part of the multi-storey buildings and beams supporting canopy slabs, are not only subjected to<br>bending moment but also to a shear load. Glued-laminated bamboo is classified as a viscoelastic material<br>since it shows the properties which are common to both solid and fluid. In the long-term constant or steady<br>loading, the glued-laminated bamboo will cause creep deformation. This paper discussed the experimental<br>investigation of the creep behavior of glued-laminated bamboo subjected to pure shear. The specimens were<br>apllied constant load with the different load level 20%, 30% 40% of the ultimate shear capacity. The<br>instantaneous or elastic deformation was recorded after 1 minute a constant load was applied, then the load<br>was maintained for 180 days. An intensive recording was done every 5 minutes for 60 minutes (1 hour),<br>every 60 minutes (1 hour) until 300 minutes (5 hours), then every day until 90 days, every 1 month until 180<br>days. The results showed that creep shear deformation, strain and rate depend on load level. Creep shear<br>deformation, strain and rate increased when the load level increased. The Burger and Power law model were<br>used to fit the creep data and then can be used for predicting primary and secondary creep stage. The models<br>were successfully for predicting viscoelastic creep shear parameters.<br><br></p> ER -
