Assessment of the loading waveform on the cyclic liquefaction resistance with Hostun 31 sand

This paper was aimed at highlighting the impact of loading waveforms on cyclic liquefaction resistance sand. The test specimens were reclaimed by dry tamping method with Hostun 31 sand, and density sand matrix controlled to be 0.70. Three sets undrained triaxial tests performed altering as follows: triangular, sine rectangular waves. waveform experimentally observed axial stress applied. Under same amplitude loading, it found that wave led most severe a result greater imposed force acting for longer duration. triangular lowest softening, case in between. Consequently, terms strength curves, diverse curves related observed, curve located part graph, thereby reconfirming its higher potential. An in-depth analysis dynamic properties suggested development damping ratio progression shearing is intrinsic given fabric under certain initial confining stress. A unique relationship between shear strain could roughly established. However, number cycles required trigger level remained function waveform. novel parameter proposed this basis Arias intensity order unify response. Compared conventional method, one advantages ability express combined influence through time-integral loading.
