摘要
本文根据虚拟荷载法．推导了双筋部分预应力Ｂ类构件开裂截面应力的实用计算公式．并附有计算实例。对Ｂ类构件的判别方法和配筋设计进行了简要说明。
The stress expressions for cracked section of doubly reinforced partially prestressed concrete member of category B are derived by means of the virtunl load method.A practical example is given. The method of judging the member and reinforcement design is briefoy described.
