摘要

•The effects of sulfur content and polypropylene fiber on the mechanical properties, failure pattern and damage evolution of the CSTB were systematically studied.•The fiber factor γ is introduced to measure the impact of polypropylene fiber on mechanical behavior of CSTB.•The piecewise damage constitutive model taking fiber factor γ into consideration was established.
