The inclinometer tube is made of plastic materials, and is often exposed to the sunshine, which may result to changes in its structural behavior.
(3) Eliminate the influence of temperature on the measurement data Because the probe is made of elastomeric material, it will deform within a certain range influenced by temperature change.

Reinforcement details and stud layout (measurements in mm) Material properties The tensile properties of the steel plates, reinforcements and studs were determined from tests on random samples.
The first crack loads of the SPCC beams were calculated in the same way from known values of the properties of materials, and the experimental values were obtained from observed first crack loads in the tests.
