| Abstract: | The post-tensioned cohesive prestressed concrete beams of Geological Survey R ＆ D Building of Hubei Province are studied. Two beams of the roof plate are taken as the test object and prestressed friction loss, deviation between theoretical extension value and actual extension value, anchor deformation and midspan anti-arch value are tested. Test results show that design and construction of the post-tensioned cohesive prestressed concrete beams are safe and reliable. |
