| Research Abstract |
Cracking atrength and long-term deflection of partially prestressed concrete member with arbitrary cross section considering time dependent losses were analysed. The results obtained in this study are summerized as follows:
1. Systematic analysis of cracking strength and deformation of partially prestressed concrete member was performed. Prestress losses at arbitrary time was claculated by aging coefficience.
2. Computer programm based on the analysed results was developed.
3. Initial prestress level designed for partially prestressed concrete members including hollow slad bridges.
4. Cracking width and cracking controle of partially prestressed concrete members have been studying.
