伪静力试验(Pseudo-static tcst)是指和用驱动器对试验体(结构或构件)进行低周循环作用的一种静力试验。这种试验的目的,大多数是研究试验体在超过弹性极限以后的性能。试验中通常是先按某一位移(或荷载)循环几周,待反应稳定,再加大振幅,再循环几周。如此逐步增加,直至破坏。 Pseudo-static tcst refers to a static test in which the test body (structure or member) is subjected to a low-cycle effect using a driver. The purpose of this test is to study the properties of the test body after exceeding the elastic limit. In the test, it usually starts with a certain displacement (or load) cycle for a few weeks, until the reaction is stable, then increase the amplitude and recirculate for several weeks. This gradually increases until it is destroyed.
