| Abstract: | Taking a practical engineering background,discussed in an underground garage has been overloaded condition,the use of internal force control with active support and increase the cross-section method of prestressing reinforced the design process.The design of working conditions through multiple combinations internal force calculation,checked the ultimate bearing capacity of beams,cracking,deflection.And useing finite element stress distribution on the beam to check the situation,verify the rationality of its design and reliability. |
| Keywords: | prestressing equivalent load calculation calculation of prestressed pole nominal stress |
