钢结构在地震荷载作用下的大塑性交变应变测试方法研究
|
摘要
针对钢结构在抗震性能试验中，测试大塑性交变应变时存在一些问题研制出了一种新型试件光栅-胶性超微粒光栅，使交变性大应变可用云纹法准确而方便的获得．通过实验验证，其应变测试范围为-40％-40％，并应用到工字型钢柱的抗震性能试验中去，获得了满意的结果．
In this paper, problems exist in measure of largy plastic cyclic strain have analysed , in theearthquake resistant propertieS test of structures and have developed a new type specimen grating-gluey superpareicle grating The grating make moire was used to measurement of large cyclic strain with great ease Socpe measure of the Strain reached -40% - 40% has been proved by test. And also , the application of thespecimen brating in earthquake resistant properties test study of I-steel pillar, got a good resuit.
