EXPERIMENTAL STUDY ON THE PERFORMANCE OF SP PRESTRESSED HOLLOW SLABS UNDER HIGH TEMPERATURE

摘要

The pferformance of SP prestressed hollow slab under different high temperature and after different high temperature is studied by test. Some macroscopical phenomena are observed under and after high temperature. The bending deformation of ascending and lowering the tempera ture is analyzed. Research on high temperature effect on crazing-load and the ultimate load is carried out as well.
