Abstract

The analysis of prestressed stretching construction by software SAP2000shows that prestressed stretching has a big influ-ence on the internal force and deformation of side span frame girder and nearby floor slab when the joint action of reinforced concrete frame,ribbed beam floor and bracing system is put into consideration.The inverted arch value of frame girder,compression value of beam end and concrete stress of the beam approximate to the measured value when the restriction of the floor is put into consideration.The model can reflect the actual work situation more accurately when three dimensional calculation of ribbed beam floor is considered.
