本文提出了对预应力轻骨料混凝土由于收缩、徐变引起预应力损失值的计算方法及影响计算值的有关系数,并给出设计建议值用表。这一建议已为我国的《钢筋轻骨料混凝土结构设计暂行规定》微求意见稿所采用。
This paper puts forward the calculation method of the loss value of prestressed prestressed lightweight aggregate concrete due to shrinkage and creep and the relevant factors affecting the calculated value, and gives the table of design recommendations. This proposal has been adopted for the mini-draft for the provisional regulations for the design of reinforced concrete lightweight aggregate concrete structures in China.
