摘要：

For the prestressed concrete girder with broad bottom slab such as box girder or trough girder, if there is no transverse prestressing, harmful longitudinal cracks may appear because the concrete of bottom slab is subjected to longitudinal prestressing and transverse bending in the biaxial stress condition of tension and compression. No regulation about the transverse prestressing is specified in the Professional Standard of the People's Republic of China JTG D622004 and TB10002. 32005, and also the corresponding codes in other countries are immature in this regard. An improved code is proposed to make a definite regulation to ensure the bridge's safety.
