【摘要】 通过对2块不开洞和6块开洞无黏结预应力混凝土板的实验,分析了荷载与挠度的关系,通过实测挠度值与计算值相比较,发现实测值大于计算值,分析其原因,主要是板的结构形式、支承梁、开洞及洞口位置等这些因素对挠度产生了影响。更多还原

【Abstract】 Based on the experimental results of 2 unbonded prestressed concrete slabs and 6 unbonded prestressed concrete slabs with openning,the relationship between load and deflection was analysed.Through the measured values compared with the calculated values and found that the measured value is more than the calculated values,analysis of its causes,mainly the structure forms, supporting beams,open hole and the hole location on the deflection ofthese factors had an impact.更多还原
