【摘要】 钢纤维水泥基复合材料初裂强度的计算公式目前尚未统一，很多文献中都直接沿用了短纤维增强延性基体复合材料的计算公式，本文推导了适用于钢纤维混凝土等乱向短纤维增强脆性基体复合材料的初裂强度计算公式。更多还原

【Abstract】 The calculation formulas of composite material initial crack stregth in steel fiber cement base haven’t been unified so far. The calculation formulas of the composite material in short fiber reinforcement ductile base had been used directly in many documents. In the paper, the initial crack strength calculation formula of the composite material is derived, which is suited for the disorder short fiber reinforcement brittle base in steel fiber concret and others.更多还原
