Abstract:The general introduction of ice hockey gymnasium in Harbin institute of physical education is introduced. Arrangement and tension methods for prestressing reinforcements in two-span prestressed concrete beam are presented in which length of span, depth of beam and number of prestressing reinforcement in the same axis are different. Some calculation processes are given such as placing of prestressing reinforcements on the basis of equations of crack control, placing of nonprestressed reinforcements on the basis of resistance and construction requirements, deformation check and so on. All these can provide references in design and construction of the similar project.

Keywords:prestressed concrete; two-span frame beam; equivalent load; crack control; deformation check
