The Stress Measurement of Membrane Type LNG Storage Tank
멤브레인식 LNG저장탱크 응력측정법
Abstract
In LNG Tank, it is very important to measure the strain in Membrane by theoretical and experimental stress analysis. In this paper, perform the test about strain gage, thermal sensor and lead wire to make clear the properies. The test results conclude that stress measurement by strain gage must consider the effect of many factors to measure strain acculately. The corrections should be made on apparent strain, lead wire length and Membrane shape. It is also important to measure the temperatures accurately at the strain gage location
