【Abstract】 Optimizing a prestressed concrete T-frame beam, selecting reasonable effective height of section and prestressed steel area can improve the beam’s performance and reduce the cost. According to the current standard, a lagrange-multiplicator mehtod is introduced to optimize the prestressed concrete T-frame beam and a practical formula is deduced in this paper.更多还原
