摘要
结合实际改造工程 ,就无粘结预应力楼盖轴向预应力效应以及开洞改造后板的抗弯承载力计算 ,进行了分析讨论 ,为改造工程设计和施工提供了理论依据。
Combining with a real project,the axial\|prestress\|effects and the load\|capacity of opening reconstructed slabs with unbonded prestressed tendons have been discussed in this paper, which presents a theoretical basis for the design and construction of a reconstruction.
