Short span bending tests
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.

Splet21. maj 2014 · Three-point bending tests are often used to determine the apparent or effective elastic modulus of long bones. The use of beam theory equations to interpret such tests can result in a substantial underestimation of the true effective modulus. In this study three-dimensional, nonlinear finite element analysis is used to quantify the errors inherent … SpletINTRODUCTION The Modular Span Multi-Cell Box Girder System was developed for small span bridges of spans from 6 to 30 m. The bridge deck is assembled of steel modules …
