Abstract:The prestressed concrete structure is adopted in an underground natatorium in Harbin. Considering the load on virescence region differs greatly from the one on the fire engine region on the roof, the prestressed concrete frame is designed and calculated respectively corresponding to different load regions. The calculation model of structure is different in construction stage and serviceability stage due to placing of post-pouring belt, therefore, the calculation method for the internal force of structure is explained. Combine with this project, the calculations method for prestressed concrete beam and frame column are introduced. Some problems frequently occurring in design and construction in actual projects are emphasized such as determination of compressive steel bar, checking on deformation of prestressed concrete beam, tension scheme of prestressed steel, position of longitudinal steel bar and prestressed steel in column, arrangement method of non-prestressed longitudinal steel bar in the region of crossing of two beams, prestress technics and grouting processing, arrangement of non-prestressed longitudinal steel in post-pouring belt and construction of anchorage on the end of beam. All these can be served as reference in construction of the similar projects.
Keywords:prestressed concrete; frame; calculation of internal force; construction scheme
