摘要
构件试验中破坏试验常常规划成对称的,因此,在布置扑捉破坏现象的仪表时,往往也对称布置。实际上,对称双方破坏的概率不一定是相同的,这需要深入一步的分析。以钢筋混凝土受弯构件简支梁在对称集中荷载作用下的斜截面破坏为例,探讨了这个问题,发现对称截面剪切破坏的破坏概率并不相等,这个结果对构件破坏试验有重要参考意义。
As destructive tests are always symmetrical in the experiments, the instruments for capturing the destruction are usually designed symmetrically. In fact, as probabilities of both ends of the symmetrical members are not always the same, further research is needed. This paper, by taking as an example the destruction of oblique section caused by the reinforced concrete simply supported beam under the symmetrical converged force, aims to illustrate that the probabilities of symmetrical sections are not equal. This result is of great significance to the component destructive tests.
