SpletShort-Span Compression Test (SCT) with ZwickRoell. A very stiff test arrangement keeps the influence of the machine on the specimen to a minimum. Specimen and load cell are located in the same symmetrical axis, eliminating bending moments which may distort results. Optimum specimen parallelism is achieved with the ZwickRoell strip-cutter. SpletThe bending properties of CLTB and generic Spruce-pine-fir (SPF) CLT specimens were evaluated by dynamic tests and third-point bending tests, respectively.
