A new type of cable-stayed bridge, single pylon cable-stayed bridge without backstays is used in the Zhenshui Road Bridge in Xinmi City, China’s Henan Province, which adopts PC box girder with corrugated steel webs. It has many advantages such as light girder deadweight, low pylon height and avoiding webs longitudinal cracks. This novel bridge is adopted firstly in China. Cast-in-place method with bracket is used in the construction of the bridge’s inclined pylon because of its complex construction technology and tight construction period. In this paper, interests are focus on the scheme comparison and selection of bracket construction, the establishment of bracket’s computational model and the result of numeric analysis etc. The chief aim of this investigation was provides useful reference and enlightenment to similar bridge types.

The axial performance of CFRP is excellent, while the lateral compression strength and shear strength are low, thus they can’t be anchored by traditional anchors. A new type of adhesive anchor was designed and five experimental cables were fabricated and the static tests were carried out. In the tests, the tensile capacity, bond strength and pullout behavior of CFRP cables anchors filled with resin were discussed. The efficiency coefficients and the load-slip behaviors of the bond-type anchors and the uniformities of the stresses in the tendons were studied. Several conclusions are drawn which have become powerful evidences for using the bond-type anchors in the first cable stayed bridge with CFRP cables in China.
