部分预应力混凝土多跨框架大梁张拉阶段摩擦损失及锚固损失的实测工作某加工车间为多层多跨框架结构，框架大梁设计成部分预应力混凝土四跨连续梁。为了了解地道摩擦损失及锚固损失的实际变化情况，在张拉阶段施工现场对该大突进行了实测工作。大梁总长度为４４ｍ，其中三... Measurement of Friction Loss and Anchor Loss during Tensioning of Partially Prestressed Concrete Multi-span Frame Girders A machining shop is a multi-span, multi-span frame structure. Frame girders are designed as partially prestressed concrete four-span continuous girders. In order to understand the actual changes in tunnel friction losses and anchorage losses, field surveys were conducted on the major processes during the tensioning stage. The total length of the beam is 44m, of which three...
